Hi all!
Do you happen to know what's the difference between an A330 pilot and a bushie? No?
The bushie pilots the plane! ;D ;D ;D ;D ;D ;D
.........................................................
I am a bushie and have a test for you. Please consider this:
I was flying my Aviat Husky at FL080, 120kt, clear skies, light winds. Below, a great plain, no obstacles.
At my side, my friend Jean-Paul was piloting his Douglas DC-3. We were at the same altitude and speed.
Questions: If both pilots turned off their plane engines at the same time, which plane would reach ground FIRST? Why?
Good luck!

The one with the worst glide ratio, or the one with the highest stall speed ;D

Hi João!
OK. BUT:
Which one will reach ground first? The Aviat or the DC-3? ;D
Daaaaang!

It would seem to me that, assuming neither deploys flaps and both immediately set up for best glide speed, the DC3 (although larger) is a much cleaner design overall - even with two feathered props - and will have more inertial energy stored up due to it's higher cruise speed. The wing is also designed to be more efficient up at 8000 than the Husky's. My best guess is that the Husky would reach the ground first.

Hello Dan! Congratulations! Your answer is correct!  Now for your prize! 200 pounds of genuine Brasilian coffee, in sacks. Virtual, course! heh, heh, heh. |

Not so fast ;D ;D ;D ;D Valmee said they were both cruising at 120 kts  But I do agree with the answer |

OK, bring on the virtual coffee. Extra-strong, no milk or sugar.

The DC-3 would have to come down first. There is more drag on the 3 than on the Husky, so it will slow down faster. Also its weight will want it to come down. Another thing that seals it as the 3 first is the fact that you will have to crank the gear down by hand, because with both engines off, you have no hydraulic pumps to lower the gear as normal. As the gears come down, there will be more drag induced meaning you'll have to come down steeper to maintain airspeed. You can't wait until short final to start cranking those gear down. It does take a while! The flaps I believe are also hydraulic, so it will be a race to the ground for the crew to get her down in one piece due to all the pumping that will be needed.

where was it mentioned that the gear had to be deployed and where was it mentioned anywhere about finals. The original question was I quote " Which would REACH the ground FIRST" no mention of intact safe landings. :-D

Same answer. The 3. Since the speeds are the same, the 3 doesn't have much of an advantage, other than the volume of mass is bigger, giving it more of a push. But, because of its size, drag will affect it more. The 3 stalls before the Husky does. It has to get down at a faster speed. The real answer lies within the wings aspect ratio. I'd say the Husky's is higher.
Also, it doesn't say either way on the gear, does it? An assumption using an absence in a statement, doesn't mean that absence doesn't really exists. Also , show me an airplane that never flew a final, and I'll show you an airplane that never landed yet. ALL airplanes have a final approach.

OK .... After some research, the Husky's aspect ratio is 7.4:1. The 3's is 9.1:1. Husky should hit first. There are many variables that may or may not reverse it.
