It seems that the floats are sticking at the pivot point. I removed the units and I can move the floats by hand but when I lift the float to the full position and release it, it remains. If I shake or jiggle it, the float will drop. Is there some way to free up the mechanism? I am afraid that as I burn fuel, the sender won't follow the level. Any ideas?

Slider --> RV-List message posted by: "Jerry Grimmonpre" List readers ... Is the problem, of a leaking canopy, due to vent air (heated or cooling) coming in and slightly pressurizing and billowing out through the cockpit/canopy cracks? Opinions. When the ram air enters but has no outlet in the airframe, it would seem that engineering an outlet would help to keep the cockpit/canopy junctions tighter. Is there a known low pressure area on the airframe that will promote "flow through" ventilation without generating noise or allowing exhaust gases in? It seems that an engineered flow through vent system would help with the noise of escaping air around the canopy. Has anyone tried a flow through venting system?

IMHO, correct me if I am wrong. Here goes: Best glide rate is a function of incidence, not of speed. Best glide speed is an average. A heavily loaded plane will have a best glide speed faster than a lightly loaded plane, but the incidence will be the same. Same thing for stall - a heavily loaded plane will stall at a faster speed than a lightly loaded plane, but in both cases at an identical incidence. Air density, i.e. temperature, altitude, will also affect the best glide speed value. That is another reason for getting an AOA, which I happily have installed on my left wing. If you suddenly become a glider, get your AOA onto your best glide incidence; keep it there and forget the speed, you might gain a few hundred feet or a couple of miles. I would tend to think that the prop will have no effect on the best glide incidence. Added drag will decrease the best glide slope but it will not change the best glide incidence. This means that with an AOA, you can maximize your distance whatever the conditions. If, once you got onto your bets glide incidence you managed to time the ft/min drop and observed your speed, you'll quickly know just how far you can go before touchdown. Hope that I have not made some gross mistake - would appreciate some knowledgeable aerodynamicists to confirm this issue. And if I am correct, the above would be a compelling reason to install an AOA.

Actually that isn't a given. I worked this out once, it seems that the break point is how high you are when you make the decision that you're landing. If you're still above your normal circuit height, there will be a net gain in gliding distance realised by stopping the prop. The reason is that when you raise the nose to stop the prop, you climb a bit above your (windmilling) ideal glide path. Once it's stopped, you may dip below the ideal (windmilling) glide path briefly while you get your airspeed up to best glide again, but the resulting new (prop stopped) glidepath will be shallower and will end up crossing the previous path well before touchdown. Now, this was worked out for a Cessna 150, and that only required slowing to 55mph or so to stop the metal prop... Which isn't much below best glide. If you've got a wooden prop, it's likely you won't need to raise the nose much to stop the prop, so you won't lose much by doing so. Still, I probably wouldn't try it unless I was over 2000' AGL, or unless I knew the second it happened that I needed every inch of gliding distance to make it to a field. > For the reasons above I don't think stopping the > prop is reasonable or even possible in many cases and therefore > objected to calling it THE realistic condition.

AOA is a very nice insrument to have, i'm surprised that generally it's just the military that has them. They aren't particularly expensive, is there some downside to them that people don't generally talk about? And yes, you are correct. The AOA shouldn't change for best glide, but you can be sure that with the reduced drag of the windmilling prop, that you will have an increased *range* at that best glide incidence. Which means you might make it over that last farmer's fence or powerline before hitting your ideal landing spot. > Hope that I have not made some gross mistake - would appreciate some > knowledgeable aerodynamicists to confirm this issue.

I will agree that a stopped prop represents the lowest drag configuration which in turn nets better sink and glide ratio. What I don't agree with is whether it is "realistic" (or wise) to do what it takes to get the prop stopped in any given engine out. If it occurs at 400 AGL and 80 mph I would assert that it is decidedly unwise as you'll be on the ground in 10-15 seconds. At 10,000 AGL and 170 kts you have more freedom to optimize things. Somewhere in between there's a transition point from unwise to possible to desireable. Slowing the aircraft below best glide speed to stop the prop and then regaining airspeed to best glide involves some loss of gliding range. How much and whether you can recover it with the lower drag (and how long it takes) is anyones guess. There are 4000 RVs flying and over a thousand folks on this list and I've still not seen any performance data solid enough to do that kind of trade-off study with any confidence. So we're left with our judgement to decide. My reasoning is that at low altitude (pick your own definition, 0-3K AGL?) your options are most limited and fast and correct decisions are most critical. It's not the time to approach stall in an emergency and you've got enough other things to do in the time remaining. At high altitude you may have many more options so the ability to eek out the last bit of glide range may not be that valuable. You're likely to gain more by correctly judging the effect of the wind on your range and available airports. At any event I would leave stopping the prop until after all the essentials are completed and all restart attempts are done. At that point you've lost more altitude and marginalized the benefits somewhat. My view of "realistic" is what is conservatively attainable in real world conditions. For the reasons above I don't think stopping the prop is reasonable or even possible in many cases and therefore objected to calling it THE realistic condition. It's certainly subjective so YMMV. Regardless of your view, it's important to periodically evaluate your views and practices. Regards, Greg Young - Houston (DWH) RV-6 N6GY - project Phoenix Navion N5221K - just an XXL RV-6A Greg: Good post. I have not tried to establish my RV-4's performance with the prop either stopped or windmilling but do have some anecdotes that may shed some light on what happens (or not). The first involves a 260hp Cherokee Six and its owner, my instructor. A discussion of the time required to regain power after running a tank dry resulted in a demonstration. While I was flying he moved the fuel selector to an empty tank. Presently the engine stopped producing power. The change in sound was not dramatic but was certainly perceptable. He then switched to a tank with fuel and we timed the interval until restart. My recollection is that it took 13 seconds. Seemed a long time. The engine continued to turn at governed speed and most of the 13 seconds were spent slowing down. Only a little altitude was lost near the end of the 13 seconds. The second was a forced landing exercise in my -4. We were at cruise at about 1500' AGL when the throttle (not the mixture) was pulled. Since I was busy picking a spot and setting up for an approach I did not time it but there was a lot of time available in level flight before getting down to glide speed. The third was an occasion when I was running prop performance tests. I had set up a two way course between the Davis Besse and Enrico Fermi power plants over the western end of Lake Erie. It was early in the morning and the air was as stable as it gets around here during warm weather and I was at full throttle and concentrating on holding altitude to plus or minus 10 feet when I ran a tank dry. Not very bright, I'll admit, but it happened. It took perhaps 1 second to recognize what had happened, a couple more to switch tanks and only 5 or 6 more to get power back. The throttle was not moved, no altitude was lost though there may have been a bobble when I reached for the fuel selector, and not more than 15 knots of speed were lost. Now a fourth incided occurs to me. At about 150' while climbing out of the airport in a 65 horse Aeronca Champ the instructor pulled the throttle and said "where're you gonna put it?' I dumped the stick and pointed at the biggest open space I could see. Some thoughts: If I set up speed reciprocals between those two nuclear power plants today I would expect F16's with armed missiles pretty soon. Proper response to power failure is totally dependent on height and flight conditions at the time. A fast, clean airplane at high speed provides more time to establish a course of action. If low and slow whether the prop is turning or not, while not without consequence, likely must be accepted as it is. Likewise, a slow, high drag bird like my neighbors UPF7 requires a response different from that of an RV. If you have time to experiment with stopping the prop without jeopardizing the outcome, it's your hide you're playing with. If you are high and fast and can zoom to a speed that stops the prop perhaps a better chance to succeed can be found. If you screw it up, all bets are off.

I ended up putting the washers back under there and I'm hoping that maybe someday it'll settle enough to remove one or both of them. The skirts were fitted by the work the twist into them across a thigh method and then pulled down hard by a helper while they were drilled and clecoed.

Since I haven't completed the RV6A, I haven't tried to get the data myself. Burt Rutan published the glide performance for my VariEze in the Owner's Manual showing two scenarios: 1. The engine out with prop windmilling; and 2. the engine idling. The glide ratios for these are about 10 to 1 and 17 to 1 respectively. Later on, he tested the VariEze to obtain the speeds necessary to stop the prop and to get it going again with a Continental 0-200 engine installed. These speeds were about 70 Knots and 110 Knots if I recall correctly. If your engine stops when you are close to the ground, stopping the prop is probably not an option as others have pointed out. But at 8,000 feet altitude it's a slam dunk IMHO. BTW these start and stop speeds will vary depending on actual aircraft model, engine, and propeller. When I had my Continental engine failure in my VariEze due to a seized exhaust valve, I obviously didn't have to consciously stop the prop. This occurred at about 4.5 miles from the threshold of the airport runway I just left at Victoria Intenational and I had just leveled out at 2,500 feet (airport is at 63 feet AMSL). I was still at climb speed of 120 mph. I declared an emergency and had to turn about 210 degrees to my left to establish the glide directly to the button of runway 090. The wind was about 5-10 Knots coming from my left. I immediately started looking for a place to land but soon determined that the runway was within gliding distance. When I got near the airport I actually had to purposely lose altitude. I could have used a closer runway. I landed about half way down the main active 7,000 foot runway, where I could turn off onto a taxiway to get out of the way. It turns out the gliding speed I used, about 100 mph, was about 15 mph above actual best gliding speed. Since I know pretty accurately where I was when the engine failed, I can calculate my actual gliding ratio which turns out to be something better than 10 to 1 (worst case). So optimally the engine stopped gliding ratio for the VariEze is probably about 12 to 1, or somewhat better than the prop windmilling value. An interesting side note. To be honest I can worry about a lot of things when I'm flying but when this incident occurred I had no panic at all. I just had a job to get done. I even thought I would lose it some time after I landed. That didn't happen either. The guys in the firetrucks were a lot more concerned than me. It's funny how your brain works. Some of this is off topic, but I hope it's informative.

Doug: The pilot in command is the pilot getting the BFR. The instructor giving a BFR to a current pilot is not the PIC. When he said to you, "What if the engine does not start?" that was a very valid question. What if cut-off is used in training and the engine does not come back in time or at all? The FAA would rightly blame the CFI. I think CFIs should provide realistic training with out undue risk to the student or yourself. Doug if you feel it is safe, that is your judgment call, but I respectively disagree with your suggestion that a CFI who does not use idle cutoff is unworthy some how to teach. You don't have to simulate an emergency with a real emergency. Regardless what is under you at the time, loss of power, intentional or not, in a single engine airplane is always an emergency. Pulling mixture in flight has risks. Not sure what you are advocating, but if you are suggesting dead stick landing practice with the mixture in cut-off, I would say that is unnecessarily risky, and I know if an accident resulted the FAA would agree. I agree at 3000 feet over a long runway and engine failure should be no problem. However what if? Vehicle on runway, you miss judge and the engine wont fire up? It has happened. If you are alluding to simulating engine out glide, in a single engine airplane, with partial power and flaps. That is a great idea. However you demonstrated glide performance by actually using idle cutoff? Why? Could you not just tell the pilot what the best glide ROD-rate of decent is and appropriate speed, without shutting the engine down? BTW 900-1000 fpm @ 96 kts is a good number for most RVs (1.4 to 1.6 nm/1000ft). I know it is not as macho, and the law of INTENSITY says making it "real" enhances learning but not if the student is scared. It sounds like you took that into consideration and explained this. I would say just tell the student what to expect from experience without demonstrating it with idle cutoff, and simulate using partial flaps at idle power as you apparently did. Again great idea. I would say anyone who has a CFI that says you must practice with idle cut-off, whether at high altitude or low, go find another CFI, If you are not comfortable with it. Even going to idle power has some risks, like carb ice, thus CFIs check or clear the engine occasionally. In defense of Doug he apparently he has supreme confidence in making a dead stick landing and limits the risk by practice over a runway, but is that extra risk for realistic training needed? It is not common to use idle cutoff and some would say, including the FAA, not necessary. In the early days of multi-engine training, engine failures were simulated with with idle cutoff mixture. Many accidents resulted from this practice. Engine failures on takoff and landing for multi-engine airplanes are now simulated with idle power (per the FAA PTS-practical test standards). Feathering the engine is done by using simulated with "zero thrust and partial power. I would say that is a good conservative approach to carry over the SE airplanes.

He said, "I don't know, I suppose around 500 fpm." I said we would go up over the airport and pull the mixture and find out. He was concerned about that. I asked him why? He said "What if it doesn't restart?" We land, I replied. If anyone is concerned in the least about an engine failure at 3000 AGL directly over a 6500 x 250 ft runway they should not be flying single engineairplanes. We pulled the mixture and flew best glide speed and the airplane came down 1000 fpm measured on my watch, not the VSI. The VSI showed about 800 fpm. We found that 1/3 flaps and idle thrust simlated that decent, then we practiced deadstick overhead 360 and 180 approaches to a specific point on the runway, without going short. He did well and I would suspect his chances of successfully making a deadstick landing increased dramatically. If you are not comfortable shutting down your engine over an airport, find a flight instructor and go do it ASAP.Unfortunately most flight instructors are teaching to gain experience ratherbthan share it. If your flight instructor is unwilling to do it, find a different flight instructor. A successful outcome from a bad situation is directly related to the confidence the pilot has in that outcome. If you have realistically trained for, and successfully completed deadstick landings on a point, you will have a much higher level of confidence in the outcome and that increases the likelyhood of a successful outcome WHEN (not if) the fire goes out.

One landing & takeoff at the dual use civilian/NATO base located at Lajes Field AFB in the Azores Portugal about 10 to 15 years ago would have cost you about $200 in their pay as you go system. Santa Maria (or was it San Miguel? forgot) RAPCON and Lajes tower I believe billed by the radio call (separate charge lines for air and ground calls) and this would have been a minimal comm fee, the landing lights are a fee, the ramp fee regardless of whether or not you buy gas, weather brief, flight plan filing, etc are what is in that bill. Nothing to do with the fuel charge which was out of this world as well. Even 20 years ago gas was something like 3 or 4 bucks a gallon as I recall with taxes. Tax on automobiles was 100%. Yep, your $35K Audi on the local Azorean economy cost you $70K with tax, thank you. Now it's easy to understand why so many Europeans vacation to America and fly powered planes here. They can't afford to do so there. God Bless American Aviation Infrastructure!

Where else does the government give you anything worthwhile for FREE? Hi Vince, I know this was "tongue-in-cheek", but if you come fly in Europe for a while, you'll be reminded of all the great stuff the government in the US is giving you for "free"! Just in case you don't have time to do this, here are a couple of items: o) Free landings at public airports (Here in Switzerland mine charges 25 USD, and each touch and go is counted!) o) Free IFR ATC services (the charging scheme in Europe is too complicated to describe, but tru st me, it makes the landing fees seem cheap) So, when you read those "scare" articles from AOPA about how they are working to save us from a fee-based system, pay attention! Just about every pilot I've met is a Libertarian, but keep in mind what privatization means for your favorite pastime.

BTW 900-1000 fpm @ 96 kts is a good number for most RVs >(1.4 to 1.6 nm/1000ft). Given that every RV is a bit different (different ASI errors, different VSI errors, different prop pitch, or low pitch stop setting for a CS prop), how is one to determine what partial power and flap combination properly simulates engine out unless you perform an actual engine-out glide first? The parametres that properly simulate an engine-out glide in one RV may be completely out to lunch in another one. -- Kevin Horton RV-8 (finishing kit) Ottawa, Canada http://www.kilohotel.com/rv8 ________________________________ Message 30 ____________________________________ Time: 03:13:45 PM PST US From: "D Paul Deits" Subject: RV-List: Wiring diagram --> RV-List message posted by: "D Paul Deits" Earlier this year either as a result of a list entry or reviewing a lister's site, I reviewed a well thought out wiring diagram.

Slider --> RV-List message posted by: "Kyle Boatright" On the RV-6, there is a low pressure area along the side canopy skirts. This is because the fuselage begins to narrow about 1/2 way back along the skirts, and because that area also coincides with the low pressure area above the wing. Flow through ventilation is the problem - air is sucked into the cockpit through every other orifice in the airplane and exhausts around the side skirts. You can cut a piece of foam pipe insulation in half and place it between the slider tracks and the slider skirt to seal the area in flight. I carry a couple of pieces of this stuff with me during cool weather, and it makes a huge difference in the amount of cold air blowing through the cockpit. Adding more "exit" air ventilation would only make the problem worse. KB ----- Original Message ----- From: "Jerry Grimmonpre" Subject: Re: RV-List: Tip up Canopy Vs.

You make several good points and it is clear we disagree. I do not want to argue your post point by point. My thesis is this. I believe we have dumbed down training to accommodate the low experience level of the instructors doing the training and the result is dumber pilots. I take a FAR 61.58 checkride every year in something, sometimes twice a year, and the FAA requires (Per the ATP PTS) we do a shutdown, feather, and restart, every time. I guess the FAA assumes that if you fly a large (read over 12,500#) airplane you need more "realistic" training. I can assure you that I am much better for that training/checking. The airplane I was flying for the BFR in my post was a homebuilt and the pilot had no idea of the sink rate and there was no book to look in. I have done this with several pilots and based on my experience, the learning that occurs far outweighs the risk. And you are absolutely correct, the risk is mine! With regard to the risk the mixture cable is exactly the same type of cable that controls the throttle and if it failing is the concern it is exactly the same risk as the throttle. If the carb is the concern, the chances of a throttle butterfly getting jammed are far greater than the mixture needle valve getting jammed. I fly 60 year old airplanes every weekend. Pulling the mixture over a 3000 feet over 6500 foot runway is a risk I can live with. I see pilots who have learned to fly and successfully passed FAA checkrides, and yet have no concept of how fast an airplane comes down and I continue to see pilots who think they can turn back from an engine failure at 500 feet and land on the runway they departed from. I am also a FAR 135 check airmen for the local Charter service. Recently we had a Seneca that had runout engines. We lined up all the Charter pilots, some are long in the tooth, gray haired, or no haired types. We went up high over the airport and shut one down and flew around on it. I do quite a bit of training, and I can recognize when learning occurs. Learning occurred. These guys got to see for real what single engine performance was really like. Not simulated, not numbers on a page, but numbers on a barely climbing altimeter in a lightly loaded Seneca. They got to see the importance of raising the dead and splitting the ball. Learning occurred. The restarts were a real eye-opener. One of the pilots had recently had a precautionary shutdown for an oil pressure problem and he considered a restart for landing. After a real restart, he said, "if I had tried to restart when I planned, I would have never made the airport." Learning occurred. Is there risk associated with that type of training? You bet. Is there reward? Absolutely. Can the risk be mitigated? I think so. Many ways. A through briefing. Flying at altitudes that if the other engines quits we still would have landed on the airport. The risk associated with a shutdown, feather, and restart in a B-25 is probably 100 fold greater than pulling the mixture in a light single engine airplane over a runway. I believe the current state of flight training is terrible. I believe flight instructors should be required to have 1000's of hours not a few hundred. I believe instructors should be paid similar to other corporate or airline pilots. (I am not, and do not want to be a full time flight instructor, even if the pay was better) In short I believe there are lots and lots of pilots out there who do not have a clue about the airplanes they are flying, on several subjects, engine failures are one, but there is one pilot in Iowa who has a better understanding, and I believe it was worth the risk. But then you could find several people who would say I am one of the clueless ones ;-) Tailwinds, Doug Rozendaal ----- Original Message ----- From: Subject: RV-List: Re: Long glide to landing > --> RV-List message posted by: > > > >Doug wrote: > > >I asked the pilot what the rate of decent was power off in his airplane.

The FAA would rightly blame the CFI. I think CFIs should provide realistic training with out undue risk to the student or yourself. Doug if you feel it is safe, that is your judgment call, but I respectively disagree with your suggestion that a CFI who does not use idle cutoff is unworthy some how to teach. > > > You don't have to simulate an emergency with a real emergency. Regardless what is under you at the time, loss of power, intentional or not, in a single engine airplane is always an emergency. Pulling mixture in flight has risks. Not sure what you are advocating, but if you are suggesting dead stick landing practice with the mixture in cut-off, I would say that is unnecessarily risky, and I know if an accident resulted the FAA would agree. I agree at 3000 feet over a long runway and engine failure should be no problem. However what if? Vehicle on runway, you miss judge and the engine wont fire up? It has happened. > > > If you are alluding to simulating engine out glide, in a single engine airplane, with partial power and flaps. That is a great idea. However you demonstrated glide performance by actually using idle cutoff? Why? Could you not just tell the pilot what the best glide ROD-rate of decent is and appropriate speed, without shutting the engine down?

It sounds like you took that into consideration and explained this. I would say just tell the student what to expect from experience without demonstrating it with idle cutoff, and simulate using partial flaps at idle power as you apparently did. Again great idea. > > > I would say anyone who has a CFI that says you must practice with idle cut-off, whether at high altitude or low, go find another CFI, If you are not comfortable with it. Even going to idle power has some risks, like carb ice, thus CFIs check or clear the engine occasionally. > > > In defense of Doug he apparently he has supreme confidence in making a dead stick landing and limits the risk by practice over a runway, but is that extra risk for realistic training needed? It is not common to use idle cutoff and some would say, including the FAA, not necessary. In the early days of multi-engine training, engine failures were simulated with with idle cutoff mixture. Many accidents resulted from this practice. Engine failures on takoff and landing for multi-engine airplanes are now simulated with idle power (per the FAA PTS-practical test standards). Feathering the engine is done by using simulated with "zero thrust and partial power. I would say that is a good conservative approach to carry over the SE airplanes. > > > Regards George CFI(CFII)(MEI), ATP > > > +++++++++++++++++++++++++++++++++++++++++++++ > > From: "Doug Rozendaal" Subject: Re: try-it-yourself fly-in - was Long glide to landing Date: May 01, 2005 > > > I was giving a BFR this week and I asked the pilot what the rate of decent > was power off in his airplane.

If anyone is concerned in the least about an engine failure at 3000 AGL directly over a 6500 x 250 ft runway they should not be flying single engineairplanes. > > > We pulled the mixture and flew best glide speed and the airplane came down > 1000 fpm measured on my watch, not the VSI.

They look like the type Vans sell for the RV-10, but vans says they will not work in the RV-8 wing tips, the parts person said they are to hot and would melt the tip. Where would I find what I saw in many planes at the airshow. I want to install them in the wing tip with the strobe and the nav. light. Thanks.
