1 - Modern low altitude radio altimeters emit waves in the following frequency band: VLF (Very Low Frequency). HF (High Frequency). UHF (Ultra High Frequency). SHF (Super High Frequency).

2 - A "close traffic advisory" is displayed on the display device of the TCAS II (Traffic Collision Avoidance System) by: A blue or white empty lozenge. A yellow full circle. A red full square. A blue or white full lozenge.

3 - When an aircraft has turned 360 degrees with a constant attitude and bank, the pilot observes the following on a classic artificial horizon: Attitude and bank correct Too much nose-up and bank too high Too much nose-up and bank correct Too much nose-up and bank too low

4 - An air data computer1. supplies the ground speed and the drift (angle)2. determines the total temperature and the true altitude3. receives the static pressure and the total pressure4. supplies the true airspeed to the inertial unit5. determines the Mach number, the outside (static) air temperature The combination regrouping all the correct statements is: 1 and 2 3, 4 and 5 2, 3 and 4 2 and 5

5 - The signal transmitted by a radio altimeter is: An amplitude modulated carrier wave. A combination of frequency modulation and pulse modulation. A pulse modulated carrier wave. A frequency modulated carrier wave.

6 - When descending at a constant Mach number: The difference between surrounding conditions and ISA must be known to deduce the CAS variation. CAS decreases. CAS increases. CAS remains constant.

7 - Heading information from the gyromagnetic compass flux gate is transmitted to the: Heading indicator. Erecting system. Amplifier. Error detector.

8 - The operation of the GPWS (Ground Proximity Warning System) is governed by laws taking the aircraft height into account as well as:1- the descent rate 2- the climb rate3- the aircraft configuration 4- the selected engine rpmThe combination regrouping all the correct statements is: 1,3 2,3 2,4 1,2,4

9 - During the approach, the radio altimeter indicates 950 ft. This is: The relative height of the aircraft above airport level (AAL). The height of the pilot eyes with regard to the ground. The relative height of the aircraft with regard to the runway. The height of the lowest wheels with regard to the ground.

10 - For an aircraft flying a true track of 360° between the 5°S and 5°N parallels, the precession error of the directional gyro due to apparent drift is equal to: -5°/hour +5°/hour 15°/hour Approximately 0°/hour
