Chapter lessons
1The Airspeeds: IAS, CAS, TAS and MachFollow the IAS to CAS to EAS to TAS chain, calculate TAS or Mach, and predict constant-speed layer behaviour.2Altimetry: QNH, QFE and the Altitude FamilyDistinguish QNH, QFE and the altitude family, then apply subscale and temperature corrections with the correct sign.3Temperature in FlightDistinguish SAT from TAT and explain how Mach and recovery factor control ram rise.4The DR ElementsRelate track, heading, drift, WCA, groundspeed and ETA before solving a full wind triangle.
