AIRSPEEDS

The CAS is obtained from the IAS by correcting for the following errors: 1. Position. 2. Compressibility. 3. Instruments. 4. Density The combination that regroups all of the correct statements is:

• A1, 3.
• B3.
• C1, 3, 4
• D2, 3, 4.

VLO is the maximum?

• ASpeed at which the landing gear can be operated with full safety,
• BFlight speed with landing gear down.
• CSpeed with flaps extended in a given position.
• DCruising speed not to be exceeded except in still air with caution.

When descending through an isothermal layer at a constant Calibrated Airspeed (CAS), the True Airspeed (TAS) will?

• ADecrease.
• BIncrease at a linear rate.
• CRemain constant.
• DIncrease at an exponential rate.
