As a follow-up to this thread .... all other things being equal, does stall speed change with altitude?
Uplinker - you mentioned that "pressure" is corrected for many factors to give IAS in the flight deck; not sure if this is the case ....
- CAS is IAS corrected for instrument & position error. CAS is shown in the flight deck
- EAS is CAS correct for "compressibility" effect
- TAS is EAS corrected for density
- GS is TAS corrected for wind
