|
Pressure altitude |
Height asl corresponding to a given barometric pressure under standard air conditions. Indicated corrected for pressure |
|
|
Density altitude |
Pressure altitude corrected for non-standard temperature |
|
|
Indicated altitude |
Reading on altimeter when set to current barometric pressure |
|
|
True altitude |
Exact height asl |
|
|
Absolute altitude |
Actual height agl |
|
|
Calibration error |
Position and placement of static vent along angle of attack and velocity causes error specific to design |
|
|
Calibrated airspeed |
Indicated airspeed corrected for position/calibration error |
|
|
Compressibility error |
Air compresses more readily at altitude and at higher airspeeds causing error |
|
|
Equivalent airspeed |
Calibrated airspeed corrected for compressibility error |
|
|
Density error |
Lower air density at altitude causes airspeed indicators to read low |
|
|
True airspeed |
Equivalent airspeed corrected for density error Actual speed through the airmass |
|
|
Indicated airspeed |
Read of ASI difference between total pressure in the pitot tube less than in the static system |
