Quit stalling and take this quiz!

1. 1) Assuming your aircraft's weight doesn't change, as you climb and the density altitude increases, the indicated speed (IAS) that you stall...

   Your indicated (IAS) stall speed stays the same because it is not directly affected by density altitude changes. However, your true airspeed stall speed does increase with altitude.

2. 2) Most straight wing aircraft are designed to stall at the _______ first.

   Most aircraft are designed to stall at the wing root first. This gives the aircraft more controllability, and less of a tendency to roll left or right during the stall.

3. 3) A stalled wing produces lift:

   Even though a wing is stalled, it still produces lift. However, the lift falloff is rapid as the wing enters the stall.

4. 4) What effect does weight have on stall speed?

   Stall speed increases as weight increases. At a given airspeed, an aircraft that is heavier will need to fly at a higher angle of attack in order to maintain altitude as opposed to a lighter aircraft.

5. 5) Vortex generators are designed to __________ the __________ to prevent early airflow separation.

   Vortex generators energize the boundary layer which prevent early airflow separation from occurring.

6. 6) In a coordinated turn, as load factor ________, stall speed _______.

   Load factor in a turn and stall speed are directly related. The greater the bank angle, more back pressure and a higher AOA must be attained in order to maintain altitude, which increases load factor. Because of that, an increase in load factor increases your stall speed.
