Wasn't he supposed to write about the 500B and not his struggles with getting his ME-rating? Or his passion for singles? Or how his Cessna 210 beats a King Air? Is it even wise to do a ME-rating in a complex twin? I don't think so. It sure sounds like a more intelligent course of action to wind up the fans of an Apache or Duchess to get the gist of the thing before strapping something like a 500B onto one's cheeks. Even though his account was meant to be humorous, it doesn't help that he wrote allowing the airspeed to drop below VMC would cause the plane to drop out of the sky. ("... plummeting to earth without so much as a bye-the-bye.") Didn't his instructor demonstrate that, in a single engine configuration, the engine that kills you is the live one and throttling back on the live engine is a distinct (not necessarily desirable) option when having to fly close to VMC? I have a question for you guys who have more experience than I in these matters. Kevin wrote that above a certain altitude the 500B would spin before stalling (in SE config) but at a lower altitude it would stall before spinning. (I never liked referring to loss of control due to loss of VMC as spinning. Spinning an aircraft is caused by a distinct aerodynamic configuration, regardless of the number or type of engines.) Now, if we consider that the altitudes he speaks of here are between about 18,000' and sea level, how would that small layer of atmosphere cause the aerodynamic properties of the airframe to change that much? Surely, if an IAS (pressure) at sea level mandates a certain behavior of the airfoil, it would hardly change if that same IAS (pressure) is achieved at, say, 8,000'. The groundspeed would change, we know that, but the aerodynamic behavior? I don't get it. If he implied that the higher altitude would reduce the power, and therefore the effect, of the live engine causing a lower VMC at higher altitudes, I would agree, but then his language and, so it appears, his understanding of the mechanics of the phenomenon is lacking. On page 5, he said this, "A bit lower in altitude, the Commander will stall before it starts spinning..." That doesn't sound like he's referring to the engine's diminishing horsepower at higher altitudes. Anyway, if you throw a pair of hair-dryers into the nacelles, everything he said about this in his article is out the door. Am I missing something? Oh, one more thing. The takeoff procedure his instructor demonstrated, by pulling back on the stick before the takeoff run, so that the AC can rotate spontaneously, should surely increase the takeoff run because of the induced drag. I always favored my Commander's ability to remain neutral until a deliberate rotation is executed, because, so I believe, it accelerates in a much cleaner configuration. What say you?

As for the take off maneuver, I always thought that is why you called out V1, go/no go speed for a balanced runway and Vr, as I recall was to rotate at one half degree per second until the desired angle on the flight director was achieved to maintain the second segment climb airspeed. I think if holding the yoke back would have been the most desirable way to takeoff, the Boeing test pilots would have described that in the book, especially when performance is so critical. Did I remember that correct Jim & Bilbo.? Sure hope this isn't a rating ride oral!

What say you? Nico, Thanks for putting up the article -- and thanks for putting up with such a nit wit article. Mr. Murhpy is confused about Vmc and spinning and stalls and altitudes -- at least that's what impression my quick glance at his article gave me. As to takeoff procedures, I actually taught short field takeoff with the yoke held approximately 1/2 way back to have neutral elevator at the start of the roll. Pre flight, I'd have my client sit in the airplane, pull back (it's heavy with zero airspeed!) while I watched his elevator from outside until it was streamlined and I'd shout to him, "There! Learn that placement!" During acceleration, the elevator would become light and the trick was to keep the same streamlined position -- not to pull back for the same back pressure feel -- until rotation speed. This technique did yield the best acceleration, shortest ground roll and climb out transition. Part of it is stream lining of the elevator and thus reduced drag, but part of it is from keeping the Commander from "pearl diving" due to its natural 1 degree negative angle of attack in its ground stance. Just for fun, a rough field technique on a 680 E or F is: Full up elevator, release brakes and unstick in a few seconds! Weeeeeeeeee! (now get the nose down and accelerate to save your life!) Wing Commander Gordon Life is not simple anywhere. Probably less so elsewhere. ________________________________ Message 17 ____________________________________ Time: 11:13:46 PM PST US From: W J R HAMILTON Subject: Re: Commander-List: Aviation Converters and Calculators --> Commander-List message posted by: W J R HAMILTON Tom, Three time table works pretty well, "close enough for Government work", as they say. Three degrees is 320 ft a mile, even if you ignore the 20, it's close, give or take a bit for the threshold elevation (say the African high veldt, or Leadville) and the actual glideslope. If you use Jeppesen, there are some very useful tables in the "Tables and Codes" tab. Another useful rule of thumb, particularly useful on a non precision approach, especially on a "black hole" approach is for Rate of Descent: "Half the groundspeed plus 50" Ergo: Groudspeed say 120 kt. therefor "half" = "60" + 50 = 650 fpm for a 3 degree descent. Works on everything from my 500A through to the B747-438, in my experience.
