If you hit the ground having the landing gear down (if it already is), might help absorb some of the crash energy. 2. There are often doors under the wing that open and close as the landing gear cycles, and that causes a loss of lift. Bad thing in a wind shear recover where you are close to the stall. So don't change the gear position. 3. These aircraft usually have significant increases in stall speed when the flaps are retracted. The wind shear recover procedure takes you close to the stall, so if the stall speed increased when you retracted flaps that could be catastrophic. The above reasons are not really applicable to RVs. Our landing gear is fixed, and there isn't much of a change in stall speed with flap retraction. There is a big drag reduction though. In an RV, if I was at half or one third flap, I would probably leave them there until clear of the wind shear. If the flaps were fully down, I would be tempted to retract them to about the one-half to one-third position, which should give (in theory) almost the same stall speed as full down, but a lot less drag. The CAFE foundation flight tests of the RV-6A and RV-8A found a 5 to 6 kt difference in stall speed between full flap and flaps up, at gross weight. As far as detecting wind shear, one thing that helps is if you have a standard way to fly an approach. Not necessarily a classical stabilized approach, but at least you are in the habit of flying every approach in the same way. Same flap angles, same descent angle, same airspeed, same power changes, etc. Then if some day you are doing things the same old way, and you are getting a very strange result, that should be your cue to become very, very alert and pay close attention to the VSI, airspeed, runway picture/VASI/ILS and power. If you don't like what you are seeing it is time to go around. If there is convective activity anywhere in the vicinity of the airport, or there is a cold or warm front passing through there is an increased risk of wind shear.

On my next project, you can bet I'll have one of those instead of the 478360 because of the lesser restriction and the simplicity of the installation. Two big improvements, not to mention the new triggering device. I've not had any problems with mine during the three years I've flown my RV and the nine years I flew the Cheetah; but, I'm glad to see those improvements that can really help me. It looks like the 40007E does just that. I'll save Mark's message for future reference. As for my friend's gascolator that has its problems, it is one of Van's. Granted, it can be easily fixed; but, it's the fact that he's just now starting to fly it and is already having problems. Another friend had problems with his, as well. Both were easy to cure problems; but, that's one item that I've had no problems with because I don't have one.

That is correct. You point the LEDs in the direction of the number printed on the board. Notice that all the LEDs have their legs bent in the same direction. The reason I mounted the 70 degree upward and downward LEDs toward the inside was to allow the zero degree LEDs to peek over and under a strobe mounted in front of the board in the center of the wingtip. You could, if you wanted to, bend the 70 degree LEDs towards the middle of the board instead of towards the edge of the board as long as you didn't mount the strobe flush against the board. If you think about it, it will become obvious that the upper LEDs will do the job of the lower LEDs, and vice versa. As long as two LEDs point down at a 70 degree angle, it doesn't matter where they are mounted. The same is true for the upward-pointing 70 degree LEDs. Indecently, there is +/- 5 degrees of slop allowed in the angle of the LEDs. You can look at pictures of the assembly at: http://www.killacycle.com/InstructionPictures.htm I put this together after I sent the first few kits, so you didn't get one. : ( Be sure to check out the latest version of the instructions at: http://www.killacycle.com/Instructions.htm >(3) As I started to power up the green board (using an adjustable > power supply) One of the LEDs came on "early".

Once you see then lit, there is no question in anyone's mind that these will pass FAA and will make your airplane very visible at night. I've had folks ask me to just send them the boards and they would get their own LEDs. They don't understand that these are nothing like the LEDs they get at Radio Shack. The LEDs are the major fraction of the cost of the kit. They are the hottest thing available. Note the large viewing angle. These LEDs hump out some major photons. > I then took a look at the board.

I wanted to make the board be able to run full brightness at 10.5 volts, so I only put two green LEDs in series. >It then hit me that the one comming on "early" was the > single LED.

Most folks just hook it up to a battery. ; ) Cutting the wire was un cool. The resistor is a current sensing feedback resistor. The regulator can go "full on" without it. The regulator increases the current until it sees 1.2 volts across that resistor. This could pop the LED. Like the redundancy? I paired LEDs in a way that would allow partial light in all directions if a part of the circuit failed. That is why the traces on the board go every which ways. >So far, so good.

I've found that the one register doesn't keep the front warm much less help out the guy or gal in the back seat. The problem has more to do with the amount of heat generated by the muff, on a really cold north east PA day (0-10deg F OAT) the air comming out of the heat register only feels about 40-50deg. I haven't found any way to get more heat off of my pipe. Just as an FYI - for the person in the back seat, summer-time heat relief is a much bigger issue. I added a y-pipe and second vent to the back of the pilot seat so the passenger would have air they could direct to anyplace on thier upper body. On a hot day at altitude the plane is comforable but as soon as you slow down and descend into the hot air the temp in the rear would shoot up well over 100 deg F. This was a much bigger complaint by my wife than the cold. I use a 7" long clamshell heat muff from Van's on the rear cross-over pipe which is about the only place the thing will fit. For a vent I have a NACA duct on the bottom of the left wing with a vent on the left floor next to the pilot seat and a second vent mounted to the rear of the pilot's seat.

Now I want to upgrade my RV so I can use it to pop thru the coastal overcast once in a while and to stay current. I've ordered a new Garmin-430/CDI from John Stark, and that'll be here in a couple of weeks. Putting in the 430 is no big deal (except to my wallet). Aside from the 91.411 Altimeter system/altitude reporting equipment check (I already have the 91.413 transponder check), the standard 30 day VOR check, and other equipment required for IFR flight (ie, clock, gyros...) what else is required to use the 430 in the system? Do I just note the installation in the log book, then boldly launch into the soup (of course that's not going to happen until I get enough hood time and feel comfortable using the 430), or is there some kind of DAR signoff, FSDO signoff, or some special verbiage for the log book. Any help would be appreciated. Laird RV-6 780 hrs SoCal ________________________________ Message 13 ____________________________________ Time: 10:05:33 AM PST US From: flmike Subject: RV-List: Re: Windshear --> RV-List message posted by: flmike John is correct. "Dry air" (virga generated) microbursts are common in the dry west. Here in the south they are pretty much always associated with thunderstorms. Windshear and microburst outflow are generally not a big problem for light aircraft because of their low inertia and ability to get power on quickly (unless you happen to be 100' AGL). Microburst downdrafts are a bad scene for everybody, so watch for that virga. FWIW, the strongest microburst recorded (that I know of) was recorded at Denver Stapleton on July 8, 1989 and produced a 95 knot outflow. It was a hot day with no thunderstorms. A 737 was on final, received a "90 knot headwind loss at runway threshold" warning from the ground based LLWAS, didn't believe it at first, initiated a go around / escape procedure, penetrated while climbing and accelerating, lost 50 kts of airspeed and 400 feet of altitude (from 1000'), and I believe had to change his shorts later. The sensor based LLWAS systems have been in service since the 80's at most major airports and have been updated with newer algorithms and sensors as well as integrated with doppler radar data. I don't think Santa Fe has a system, but I've been out of that program for about 6 years (lead electronics hardware engineer). Also, according to the NCAR scientist I worked with, the two airports with the most microburst activity are Denver and Orlando. And yeah, Denver is the largest with 31 sensors installed in 1995 at the new airport. Glad you got out okay and if I ever run into the 737 pilot, Capt. Levine, he owes me a beer! Mike RV-6A ------------------------- Wheeler, it sounds like you flew under a microburst. They are not uncommon in the dry, mountain west, especially in the afternoon. Basically, a shaft of virga (rain that evaporates in the dry air, Before reaching the ground) cools the air with the evaporation, and creates a column of cold air that "falls" to the ground. High in the air, the column of air will cause quite a downdraft, for a minute or so as you fly through it. Closer to the ground, the column of air causes an area of winds that blow away from it, as the falling column impacts the ground. Denver International Airport has had an experiment going on for the last couple of years with a huge array of sensors to detect microbursts, and provide automated warning to incoming and outgoing airliners.

You could go the brutality route and grind off the hex nut portion of the fittings, and just finger tight the suckers.

Someone once asked me what was our approach speed while landing on a carrier. I had no idea. I never once looked at the airspeed while on final (in the "groove" in Navy lingo.) Our concentration was solely on AOA (plus line up and the "MeatBall.") I also flew F-4s for the USAF. Same comment - AOA only with no reference to airspeed on final. No need to compute approach speeds for weight or configuration - the AOA took care of that chore. Of course, we used airspeed for other applications. But with any hard maneuvering, AOA again became the primary instrument. In both airplanes, the AOA indexer was adjacent to the windscreen and in the peripheral vision whether on final or in a dog fight.

Let us know how it goes. RE hardware, I had several problems with Vans hardware, the call outs are often wrong for AN standards. In other words the call out was too long or too short and one could go to the next more appropriate size. I finally gave up and ordered Spruce's mechanics set of hardware as I kept running out of odd sizes. The downside of this is all the other old guys at the airport have figured this out and always come begging for bits and pieces. I think what happens is the "kits" are shelf leftovers from earlier models, and or are for either/or use. I also found that many of their rivet call out lengths were off as per AC43.13. I would suspect/hope that the newer cadcam RV kits are reducing these leftover errors.

I am mystified as to why this would be so. I always thought the airspeed indicator was subject to density altitude errors equal in magnitude and direction to the density altitude effect on the wing's performance. In other words, I have assumed that an _indicated_ airspeed would give a reliable prediction of the wing's performance regardless of density altitude. As an aside (but also a corollary) I had assumed, without ever testing it myself, that in unaccelerated level flight at the aircraft service ceiling, the indicated airspeed would read a value very close to Vstall, showing that the wing, while actually moving significantly faster in terms of TAS, was seeing such thin air that it was at the critical AoA just maintaining altutude Tell me what I'm missing, somebody. -Bill B ________________________________ Message 22 ____________________________________ Time: 12:04:20 PM PST US From: Wheeler North Subject: RV-List: Cable RV-in --> RV-List message posted by: Wheeler North Gary, send me a flyer and I'll post'em around our local airports in San Diego area Wheeler Time: 06:46:13 PM PST US From: "RV6 Flyer" vansairforce@yahoogroups.com, NorCal-rvlist@yahoogroups.com, AZ_RVList@yahoogroups.com Subject: RV-List: SoCAL RV RendezVous --> RV-List message posted by: "RV6 Flyer" Want to give everyone an advance notice of the upcoming SoCAL RV RendezVous on Saturday 1 November 2003 at Cable Airport (CCB, http://www.cableairport.com) Upland, California.

Down low you look at the airspeed, see a number, and start to rotate. In the meantime you are still accelerating strongly and are quite a bit faster when you actually lift off. Up high, the acceleration is so much lower that you are trying to lift off at a slower speed. If you do let it fly off in a three point attitude, it should do so at the same indicated airspeed in either case.

This is because at sea level we learn to rotate to a certain pitch angle that we know develops the proper rate of climb. At high altitudes, this pitch angle necessarily needs to be less than at sea level, because the ANGLE of climb is much less at altitude. (Keep in mind that the angle of climb is the pitch angle minus the angle of attack.) If one flies a constant AOA, the pitch angle will be much less at altitude than at sea level. Maximizing takeoff performance is a perfect argument for having an AOA instrument.

Stall is not much lower than that in terms of how much more pull one gives to the loose stick at that low airspeed just to drop to stall speed. The one thing I'm not sure of is it better to reduce drag some if flaps are fully deployed by bringing them slowly up to 15deg? On the RV anything beyond 10-15deg is pure drag which is why it was the first thing I "felt" was right to do. My thought on it is that the drag portion of flap deployment is robbing lift energy, but I don't know if that's really valid. thx W -----Original Message----- From: Howard [mailto:rv6tc@earthlink.net] Subject: Windshear Wheeler, Just read your post concerning windshear. For background, I was an AF instructor pilot and I'm not a 737 F/O at United. We get windshear training ad nauseum, mostly due to the accidents that have happened in the past. The public stuff on the list is mostly correct. Pat Hatch had the best response with one small exception. He said in an RV you might want to go to Vx. Probably a little slower than that. His post stated correctly that you rotate to "stick shaker" in a jet. The theory is that you very aggressively maximize your AoA to fly out of the shear. To a certain degree, you disregard the airspeed, but that could be dangerous if you don't have an accurate AoA gage. The Delta L-1011 that crashed in Dallas after encountering a nice microburst, had MORE than flying airspeed when he hit the tank. Had he been trained better, they could have survived, but no one knew. So, max power, rotate aggressively to a pitch attitude that is higher than normal and be very respectful of the stall. Work the pitch attitude to keep the nose up and not gaining airspeed until you are climbing. In the 737, the non flying pilot calls out radar altitude, and vertical velocity. Notice nowhere are we concerned with speed until we are climbing out. We are strictly trained not to change configuration. If you do have to fly into the terrain, you are in the best attitude possible in this recovery position. Remember when you exit the shear, it is a mandatory call to the ATC to report it as well as the intensity, usually measured by change of airspeed, if you know. One great indicator could be your groundspeed on the GPS, compared with what it should be with the surface winds. In Denver, it isn't at all unusual for the winds to be different directions and velocities all the way down final. I have seen then go through 360 degrees on one approach, and this morning's visual, they changed through three different cardinal directions, the last change from calm to 270/10 at about 100-200 feet. So it is not at all unusual. Fly safe. Let me know if these ramblings are not coherent, and I'll try again. Keith Hughes RV-6 Finish B-737 Denver PS. Unless you have very sophisticated equipment on board, do not turn. You might turn from an area of lessor shear into the teeth of it, making for a longer recovery. ________________________________ Message 43 ____________________________________ Time: 08:09:36 PM PST US From: "Nick N" Subject: RE: RV-List: Dynon Discussion --> RV-List message posted by: "Nick N" Umm, What?

Apparently a lot of pusher planes have this issue and they are installing "keepers" on the engine to hold the seal in place. In this case, the cause was a collapsed crankcase breather line, it developed a kink somehow and didn't have a "whistle" hole in the line. This perhaps was an isolated incident on a pusher in warm weather, ice was not the problem. Now, with this thread running, I am wondering if the problem generally is caused on pushers with the fixed pitched prop without the proper oil passageway in the plug. Most all pushers I've seen have fixed pitch props, but there are some with CS with hubs salvaged from sea planes or electric adjusted props. Lets be careful out there.

First, I would check to see if the areas are hot during the time you intend to transition. Second, I would get flight following and let them guide you. Many such areas in California & Nevada and they can cause hours of deviation. Third, I would enjoy the chance to do some extra flying! K. H. (Hal) Kempthorne RV6-a N7HK flying!

You do not need their pitot tube unless you desire the AOA, otherwise any pitot static system will work. They will soon have the non-heated version of the ptiot tube available that will mount in the Gretz mount. The heated version of the Pitot will follow by a few months.

Take a look at your attitude gyro when you accelerate on takeoff roll. I asked the guys at Dynon at Arlington and they said that they eliminate these errors by using airspeed input.
