11 Aircraft Performance Flashcards
1
Q
What is density altitude
A
Pressure altitude corrected for nonstandard temperature. High density means less air. Pressure is proportional to density.
2
Q
What is the makeup of the atmosphere?
A
78% nitrogen, 21% oxygen, 1% other
3
Q
What is sea level temperature, pressure, sooner setting
A
59° F/15°C, 14.7 ilbs psi, 29.92
4
Q
How does temperature affect density?
A
Increasing the temperature decreases the density
5
Q
How does humidity affect density?
A
Higher humidity = less air = increasing density altitude, decreasing density
6
Q
What is true airspeed(TAS)?
A
Speed in relation to the airmass in which it is flying
7
Q
What is indicated airspeed(IAS)?
A
Speed not corrected for instrument error.
8
Q
What is calibrated airspeed (EAS)?
A
Speed corrected for instrument error
