Aircraft Performance Flashcards
What is INDICATED AIRSPEED (IAS)?
Airspeed shown on the Airspeed Indicator
What is CALIBRATED AIRSPEED (CAS)?
IAS corrected for instrument and position errors
What is EQUIVALENT AIRSPEED (EAS)?
CAS corrected for compressibility error
What is TRUE AIRSPEED (TAS)?
Actual speed through the air
EAS corrected for nonstandard temperature and pressure
What is MACH NUMBER?
Ratio of TAS to the local speed of sound
What is GROUND SPEED (GS)?
Actual speed over the ground
TAS corrected for winds
What is Va?
Design maneuvering speed
What is Vs?
Stall speed, clean configuration
What is Vs0?
Stall speed, landing configuration
What is Vs1?
Stall speed, in a specific configuration
What is Vfe?
Max flap extended speed
What is Vno?
Max structural cruise speed
What is Vne?
Never exceed speed
What is Vx?
Best ANGLE of climb
Most altitude over a given distance
What is Vy?
Best RATE of climb
Most altitude over a period of time
Define DESIGN MANEUVERING AIRSPEED (Va)
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
As airplane weight decreases Va _______.
As airplane weight increases Va _______.
decreases
increases
What does Vno actually mean?
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
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?
30 gallons
