A wing develops 10,000N of lift at 100knots. Assuming the wing remains at the same angle of attack and remains at the same altitude, how much lift will it develop at 300knots?
- 900,000N.
- 90,000N.
- 30,000N.

how to calculate??
In a steady climb at a steady IAS, the TAS is
- more than IAS.
- the same as IAS.
- less than IAS.

please explain...
Supersonic air passing through a divergent duct causes the
- pressure to increase, velocity to increase.
- pressure to increase, velocity to decrease.
- pressure to decrease, velocity to increase.
sauravkatwal asking:
Isn't in supersonic air flow, everything is vice versa?
Downward displacement of an aileron
- increases the stalling angle of attack for that wing.
- decreases the angle at which its wing will stall.
- has no effect on its wing stalling angle, only on stalling speed.
sauravkatwal asking:
how come aileron effect the stall?
In a turn the up-going wing causes a
- de-stabilizing effect due to increased AoA.
- de-stabilizing effect due to decreased AoA.
- stabilizing effect due to decreased AoA.
sauravkatwal asking:
Up going wing means down going aileron for that wing, down going aileron means more lift i.e more AoA and more drag?
help please!
