I'll toss more junk in your lap, if I may. To answer you question, your Va is 160 MPH or 139 knots. To compute it, find the formula under FAR 23.335. It's really ugly, but I hate math. I'm not sure what you'll have to know Va for on a FAR 135 checkride, other than playing trivial pursuit with the examiner. The practical application of Va is during your airwork, as a maximum speed to enter steep turns, or, lacking Gust Penetration Speed (Vb) established by the manufacturer, Va is a good second choice for flying in severe turbulence. I'd bet 50% power is just fine for entering your steep turns, which is the only checkride maneuver that subjects the airplane to increased G loads. As far as Vref, use 1.3 Vso, as suggested. I like that speed at no later than 50 feet over the threshold, meaning landing is assured and yes you're deep into your _____ AGL commitment-to-land zone. I prefer flying a Commander "too fast" on an IFR approach because I like #1) crisper controls and #2) easy approach arithmetic. By that I mean either 2 nautical miles per minute, or, 1.5 nautical miles per minute. This means 120 or 90 Knots. 120 Knots is way too fast for low IFR; you'll have trouble slowing to land if you break out at minimums. 100 knots is close to 90 for the 1.5 nm per minute mental gymnastics and Jeppesen publishes time to MAP and descent rates at 100 knots and 100 knots is pretty close to Vyse, isn't it? The Commanders are odd in that they're such excellent IFR platforms, but land too slowly to fly approaches at their optimum Vref speed. (In contrast, the 400 series Cessnas are no-brainers because you don't dare do anything below 120 knots ...) OK. Now you have to suffer through my Geared Engine Jihad. Why do you bring your props up prior to landing on your geared engine? Leave them at cruise value all the way down to landing. Look at your power graphs for MAP and RPM combinations. You can initiate a go-around or missed approach by adding manifold pressure to about 65% power values before having to increase RPMs on your engine, if I'm not mistaken. I advocate "loading the gearbox" with throttle first, then bringing up RPMs. This is much preferred to gear box lash from low the MAP / high RPM combination you're setting up by increasing RPM prior to touch down, which, by the way, has no practical use if you think about it. It sounds 10 times more complicated than it is but with some practice, you'll find you can arrest sink rate and miss an approach / or recover a stall with: Throttle to a 65% value add climb RPM (3000 max continuous), add more throttle for 75 to 85% power, raise flap handle; at around half flaps you'll see positive rate: gear up! and by this time your flaps are 1/4 where you can leave them to establish climb or let them continue retracting to zero if you're happy with climb performance. There's the "what if you're struck by a meteor" school of risk management, but if you don't have the time to push throttle / push props / push throttle, you don't have time to go around. And contrary to the average mind set, an IFR missed is NOT an emergency -- it's a well engineered maneuver with plenty of time for proper geared-engine power management. If you can make the climb gradient for departing that airport, you can usually make the missed quite easily since you're starting out above the runway by several hundred feet. Took me years to figure that out. (Exceptions will be certain high altitude airports and airports in fjiords, etc.) Enjoy your check ride. You'll do great!

It is also a maneuver that is sometimes only done at check ride time. Two hundred feet in a Commander going 90 knots equates to a nice fly by to me. However, I have seen some that should have been declared an emergency and had the equipment called out. bilbo ----- Original Message ----- From: "Jim Crunkleton" Subject: Re: Commander-List: Va, approach speeds, etc. > --> Commander-List message posted by: "Jim Crunkleton" > > Wing Commander, > I have to add my two cents here also. > You're right on when you say a go-around is NOT an emergency!

I don't know when/why the IFR missed and the Go-Around became synonymous with Emergency, but it has, hasn't it? Probably because our instructors gave it a sense of urgency during training that was a bit overstated for the situation.

Wing Commander Gordon ________________________________ Message 9 _____________________________________ Time: 11:04:34 AM PST US From: "Kelly Piper" Subject: RE: Commander-List: Va, approach speeds, etc. --> Commander-List message posted by: "Kelly Piper" Speaking of single-engine work -- I know it has been addressed in the distant past here, but I can't find it in the archives so I'll ask another annoying question. Obviously the geared engines should be cared for in a tender loving manner (I do my best!) but at times, like a check-ride, proficiency needs to be demonstrated in the single engine regime. What is the best practice for zero-thrust setup and execution with the GO-480's? Or dare I ask - how detrimental is it to actually shut-down feather and re-start? I've heard quite a range of answers but the depth of knowledge among the good folks of the Commander list is just plumb deep and preferable to typical hangar talk and opinions. We spent WAY too much on our recent engine overhauls to assume anything when it comes to caring for them, so any additional input is always well received. Thanks again to all.

Or dare I ask - how detrimental is it to actually > shut-down feather and re-start? > Kelly, Take the power to the "bottom of the green" for both MAP and RPM. You'll have more than zero thrust, but you'll still have an engine at the end of the day. You're demonstrating technique on your checkride and I.M.O you shouldn't be making a blood sacrifice to the FAA. As soon as you can, find a Commander owner with a direct drive model and work out what ever kind of deal you have to, to feather the left engine and fly around to get the true sense of handling and climb gradient. In the past, I think I've gotten one geared engine to restart comfortably. The rest, I gave the client a chance to go through the steps, but I just couldn't stand the grinding and grinding to get it started in the air. Maybe they would have all started eventually, but it just drives me berserk to watch all that shaking and straining out there on the wing. I always used this as an opportunity to land with an engine feathered because the deceleration with an engine feathered is so much different than with two turning that I think it's important to experience. Believe it or don't, the plane doesn't slow down as fast with one feathered, contrary to what your intuition would have you think. Since I'm raking it in on useless advice today, anyone have a few cents worth of experience of actually having to shut one down and then restart -- in real life? I figure if it gets to the point of actually needing featering a piston engine (you've done all you can do to keep it running: fuel selector, boost pumps, mixture, mags), there's probably no reason to ever restart it. Is there? By the way, aside from the IGSO-540 boys, anyone have unfeathering accumulators or electric (pre) oil pumps? I believe N400CH, a Mr. RPM FLP, has pre-oilers, but not sure if anyone else does. Those would be a big help in unfeathering, I'd think. It's all about building enough oil pressure to unfeather the prop and that's a lot to ask of a starter motor fighting with 80 to 100+ knots of cold wind.

Just one more comment: I can't recall the "bottom of the green" on your MAP for the GSO-480, but with the props pulled back, you can probably go as low as 15 or even 13 inches MAP. I don't want to give the impression that geared engines are made of glass. Quite the contrary. I think they're stout, rugged power plants. They sound really bitchin', too! They do require knowledge and operating technique that are now a rare commodities.

I fully agree with your analysis on shut-down. I've never done it and short of having to in an emergency I agree with the cold/80mph wind resisting the starter would be just more than I could bear. In practice, I have been at 13 MAP and bottom of the green with RPM for zero thrust. When I checked out in the Commander a couple of years ago that was the wisdom of the guy that I flew with. I have since poked around and found some variance (mostly with the RPM setting) and knew that asking here would be of benefit. I have discussed it with the examiner (no Commander experience) and he is agreeable with the 13" map and min RPM. Shutdown will not be necessary - I briefed him on the phone that I would not allow shutdown or jockeying the props (I always make adjustments to the props very slowly - RPM up or down). I think that the FAA is cognizant of aircraft particulars and it didn't seem to be an issue. Anybody else have further info on the topic?

During my ownership of the 520 (GO-435's), I shut both engines down several times on purpose (not at the same time of course). I always pre-cooled prior to shutdown. Never had a re-start problem although they did require a bit of cranking before coming out of feather. Although I knew it was hard on the engines, I just felt it was prudent for me to have a good "feel" for the airplane with one really shut down. Although it's hard on those geared starters, it's probably easier on the engine to shut it down rather than clatter the gearbox at idle.... I'm glad I did bother to practice single-engine work and do a couple of true single-engine landings because I did loose an engine during takeoff once. The right engine just stopped cold at about 200ft agl. Glad it was the right one because the gear were just coming up. Feathered it and climbed out easily for a return to a non-eventful landing.

Lost the right engine on 411VV last week while climbing out. Was in a 140mph cruise climb. Looked things over to see what was up decided I couldn't fix it and feathered the prop. 145mph indicated at 5000 feet holding her own at full mp and 3000 rpm. What a sweetheart single engine. and 51 years old.
