Test 10 domande Radio Navigation, tempo libero
1 - The Flight Management System (FMS) is organised in such a way that:
The pilot is able to modify the navigation database in the FMC between two updates.
The navigation database of the FMC is valid for one year.
The navigation database is read only to the pilot.
Timing the period that is taken for a transmission from the aircraft's transmitter/receiver to reach and return from a satellite in a known position
2 - How many clocks are installed in each NAVSTAR GPS satellite?
Yellow to amber to blue
3 - The main task of the user segment (receiver) of the satellite navigation system NAVSTAR/GPS is to:
Transmit signals which, from the time taken, are used to determine the distance to the satellite
To monitor the status of the satellites, determine their positions and to measure the time
Select appropriate satellites automatically, to track the signals and to measure the time taken by signals from the satellites to reach the receiver
4 - The selection of code 7700 on an aircraft SSR transponder indicates:
Unlawful interference with the planned operation of the flight
Radio communication failure
5 - During a flight at FL 210, a pilot does not receive any DME distance indication from a DME station located approximately 220 NM away.The reason for this is that the:
Aeroplane is below the 'line of sight' altitude
Range of a DME system is always less than 200 NM
Altitude is too high
6 - In relation to the satellite navigation system NAVSTAR/GPS, ''All in View'' is a term used when a receiver:
Is receiving and tracking the signals of all 24 operational satellites simultaneously
Is tracking more than the required 4 satellites and can instantly replace any lost signal with another already being monitored.
Is receiving the signals of all visible satellites but tracking only those of the 4 with the best geometric coverage
Monitor the satellites' orbits and status
7 - The selection of code 7600 on an aircraft SSR transponder indicates:
Radio communication failure
8 - The frequency of an SSR ground transmission is:
1050 +/- 0.5 MHz
1030 +/- 0.2 MHz
1120 +/- 0.6 MHz
1090 +/- 0.3 MHz
9 - Which of the following alternatives is correct regarding audio- and visual signals in the cockpit when passing overhead a middle marker?
Audio: 75 MHz, 2 dashes per second. Visual: Blue light flashes.
Audio: 400 Hz, 2 dashes per second. Visual: Blue light flashes.
Audio: 3000 Hz, alternating dots and dashes. Visual: Amber light flashes.
Audio: 1300 Hz, alternating dots and dashes. Visual: Amber light flashes.
10 - Which of the following equipments uses primary radar principles?
Distance Measuring Equipment (DME)
Secondary Surveillance Radar (SSR)
Global Positioning System (GPS)
Airborne weather radar (AWR)
