1
Q
how many types of speed are there
A
6
2
Q
indicated airspeed (IAS)
A
indicated on the airspeed indicator
3
Q
calibrated airspeed (CAS)
A
IAS (indicated airspeed) corrected for INSTRUMENT & POSITION ERROS
4
Q
equivalent airspeed (EAS)
A
CAS (calibrated airspeed) correct for COMPRESSIBILITY ERROR
5
Q
true airspeed (TAS)
A
- actual speed through the air
- EAS (equivalent airspeed) corrected for NONSTANDARD TEMPERATURE & PRESSURE
6
Q
Mach number
A
the ratio of TAS (true airspeed) to the local speed of sound
7
Q
ground speed
A
- actual speed over the ground
- TAS (true airspeed) corrected for wind conditions
