Atmosphere and Sound - Speed
8 important questions on Atmosphere and Sound - Speed
IAS CAS EAS TAS
-CAS is IAS corrected for instrument and pressure errors (also know as position or configuration error)
-EAS is CAS corrected for compressibility errors
Why use M at high altitudes
What happens to the MN in LRC as weight decreases
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
CAS/IAS if you descend at a constant TAS
TAS if you climb at constant CAS/IAS
MN if you climb at constant CAS(IAS)
CAS/IAS/TAS if you fly constat IAS/CAS into warmer area.
2 a/c flying at different FL at the same MN, which a/c has the higher TAS/CAS(IAS)
The question on the page originate from the summary of the following study material:
