Q

Define DESIGN MANEUVERING AIRSPEED (Va)

A

Max speed load limit can be imposed by gusts or abrupt, full control inputs without causing structural damage

At or below Va the plane will stall before the load limit is reached

17
Q

As airplane weight decreases Va _______.

As airplane weight increases Va _______.

A

decreases

increases

18
Q

What does Vno actually mean?

A

Max structural cruising speed

Max speed for normal operation

At or below Vno the aircraft is certified to withstand substantial wind gusts without causing structural damage

19
Q

If an airplane is flying at 100 kts ground speed and has 300 miles to its destination with a fuel burn rate of 10 gallons per hour, how much fuel will it take to make it to the destination?

A

30 gallons
