Flight Dynamics

Featured Replies

When P3D starts modifying the FDE to allow the replication of stalls in steep turns I will then call P3D a "simulator" and not a "game".

 

I don't allow my students to practice basic flying skills on any flight simulator. I don't want them killing themselves doing 45 degree turns onto final approach at slow speed and then wondering why the aircraft stalls and they end up spinning into the ground.

 

Bring on a super configurable new FDE!

Surely - DCS World ( p51d, tf51d or Fw190 ), IL2 Cliffs of Dover with the Team Fusion Patches, IL2 Battle of Stalingrad... Probably Rise of Flight too...

 

But I believe you have that too at least in the best add-on aircraft for XP10 and FSX? At least as far as the core FDM allows it too, but still plausible...

I have done exactly this numerous times in FSX....

The Alabeo Tomahawk does this in both XPX and P3D. I'm sure there are others.

How is that possible when it isn't modelled in the FSX FDE?

 

I am talking about the stall speed increasing as the angle of turn tightens - as in real life. A "gotcha" which has killed lots of novice pilots in the past.

Isn't this what you're talking about?

I don't think this video speaks for FSX.

 

The point is that in turns the stall speed increases with the bank angle, because the greater the bank angle, the more Gs have to be pulled.

 

In the video the indicated speed looks rather low, I think it should have stalled at a higher indicated airspeed.

It's not nrcessary to pull more Gs in banked flight.

As a matter of fact I was about to post that indeed this type of accident is more prone to happen when shallow turns are used then with more banked turns. 

 

I've seen a glider flip on it's back and enter a spin on such an occasion. All happens way too fast, and at the distance from the ground on the base leg, it's almost impossible to come out of such a situation without crashing :-/

I was talking about turns, and when you don't want to loose a lot of height,

than the same amount of elevator deflection as compared to a wings level attitude,

will result in a higher G situation which increases the stall speed.

It's also possible increase the elevator deflection in straight flight - they are all the same effect.

Don't argue with Gerry... you can't win... just simply walk away. He is the singular person I have on ignore on the entire internet.

But I was said is correct and if I'm on ignore why are reading me?

Stall speed is fixed in FSX?
