Maximum Angle Of Attach/Climb

Tue Apr 04, 2006 10:43 pm

Anyone know the Maximum Angle of attack/climb for the Airbus A340 family.

I remember hearing the 747 family ranges ftom 25 degrees on the SP to 37 degrees on 400.

I looking at figures based on MTOW.

B757-200 @ MTOW = 90 degrees

All joking aside, I would expect the 757-200 has the best, and Tu154 seems to climb pretty steeply also

Edit: None of this is relevant because you asked about A340 family  Wink

Thanks: but I'm looking for the A340 family

Maximum angle of attack is not directly related to the angle of climb. Angle of attack is an aerodynamic term, referring to the angle between the relative wind and the chord line of the airfoil.

Looking at a photo of an aircraft positioned in, say, a 15 degree deck angle relative to the horizon tells you absolutely nothing about that aircraft's angle of attack. For all the viewer knows, the photo could be showing an aircraft that is completely stalled and dropping straight down.

Now, I believe your original question asked what kinds of deck angles are possible during climbout in the A340 family. The only way to get a remotely accurate answer is to first specify weather conditions, weights, thrust settings, field elevation, etc. There are many variables.

Isn't angle of climb on Airbus aircraft determined by the computer envelope, so that the potential max angle of climb is actually never, under normal circumstances, achieved?
