Aircraft Performance and Limitations

• Climb rate: Aircraft will have a _______ climb rate at high pressure altitudes or when the density altitude is _____.

• reduced; low

• increased; low

• reduced; high

• increased; high

• Engine power: The ________ the density altitude, the less efficient the engine. This is due to the _____ oxygen content in the air.

• lower; higher

• higher; lower

• lower; lower

• higher; higher

• Takeoff and landing distances: Both pressure altitude and density altitude affect takeoff and landing distances. Higher density altitudes require _______ distances for takeoff and landing because the aircraft is less efficient in generating lift.

• longer

• shorter

• same

• Cruising: At higher altitudes (higher pressure altitudes), the engine may be required to work harder to maintain the same level of power.

• True

• False

• Fuel efficiency: Reduced engine performance and lift at higher density altitudes often result in a/an ________ in fuel efficiency, since the aircraft needs more power to maintain speed and altitude.

• increase

• decrease

What affect does higher temperature have on the take-off distance?

Would a head wind or tail wind reduce the take off distance?

Why would a head wind be better than a tail wind on take off?
