Question 1

A radio altimeter employing a continuous wave signal would have:

Accepted Answer

Main control station, the monitoring station and the ground antennas

Answer

A directional aerial for transmission and an omni-directional aerial for reception

Answer

An omni-directional aerial for transmission and directional aerial for reception

Answer

A directional aerial for both transmission and reception

Question 2

What is the procedure to be followed if, on a flight under IFR conditions using the NAVSTAR/GPS satellite navigation system, the number of satellites required to maintain the RAIM (Receiver Autonomous Integrity Monitoring) function are not available?

Accepted Answer

The flight may be continued using other certificated navigation systems

Answer

The flight has to be continued under VFR conditions

Answer

The flight may be continued as planned if at least 4 satellites are available and the pilot monitors the GPS-System manually

Answer

+/- 2NM or better for 75% of the flight time

Question 3

Due to 'Doppler' effect an apparent decrease in the transmitted frequency, which is proportional to the transmitter's velocity, will occur when:

Accepted Answer

The transmitter moves away from the receiver

Answer

The transmitter and receiver move towards each other

Answer

There is no relative movement between the transmitter and the receiver

Answer

270 NM
