The certification requirements are detailed in CS 25/2

Answer

The certification requirements are detailed in PART-CAT

Question 2

When climbing at a constant Mach number:

Accepted Answer

CAS decreases.

Answer

Difference between surrounding conditions and standard atmosphere must be known to deduce the CAS variation.

Answer

CAS remains constant.

Answer

CAS increases.

Question 3

During the approach, the radio altimeter indicates 950 ft. This is:

Accepted Answer

The height of the lowest wheels with regard to the ground.

Answer

The relative height of the aircraft above airport level (AAL).

Answer

The height of the pilot eyes with regard to the ground.

Answer

The relative height of the aircraft with regard to the runway.

Question 4

Given:Pt: total pressure Ps: static pressurePd: dynamic pressure The altimeter is fed by:

Accepted Answer

Ps

Answer

Ps-Pt

Answer

Pd-Ps

Answer

Pd

Question 5

The Ground Proximity Warning System (GPWS) generates the following sound signal or signals when the aircraft is sinking after a take-off or a go-around:

Accepted Answer

DON'T SINK repetitive only

Answer

DON'T SINK always followed by WHOOP WHOOP PULL UP

Answer

WHOOP WHOOP PULL UP repetitive only

Answer

DON'T SINK followed by WHOOP WHOOP PULL UP if the sink rate overshoots a second level

Question 6

With EAS and pressure altitude (Zp), we can deduce:

Accepted Answer

CAS.

Answer

Answer

CAS and TAS.

Answer

IAS.

Question 7

Equivalent Air Speed (EAS) is:

Accepted Answer

Calibrated Air Speed (CAS) corrected for compressibility error.

Answer

True Air Speed (TAS) corrected for compressibility error.

Answer

Calibrated Air Speed (CAS) corrected for density error.

Answer

True Air Speed (TAS) corrected for compressibility and density errors.

Answer

3 phase AC for sensor plus 28V DC for gauging

Answer

28V DC for sensor plus power for gauge lighting

Answer

3 phase AC for sensor plus 26V AC for gauge lighting

Question 9

The principle of the Mach indicator is based on the computation of the ratio:

Accepted Answer

(Pt - Ps)/Ps

Answer

(Pt + Ps)/Ps

Answer

(Pt - Ps)/Pt

Answer

Pt/Ps

Question 10
