The range of a VOR is affected by... daylight interference. reflected sky waves. multipath propagation of the ground wave. transmitter and receiver altitude.
The distance measuring equipment (DME) determines the distance based on the principle of... time measurement. Doppler. laser measurement. phase comparison.
The DME reading is a... ground distance. air range. air range. slant range.
The differenz between indicated DME slant range and horizontal distance from the DME station increases... when circling around the DME station. when descending. when departing the DME station. when approaching the DME station.
Using primary ground radar, the direction of the aeroplane in relation to the antenna is determined by... the pulse pair interval. the orientation of the antenna. the frequency shift of the received pulse. time measurement.
Which instantaneous information can be obtained from ground radar equipment? Distance and direction Airspeed (TAS) and distance Airspeed (TAS) and heading Direction and airspeed (TAS).
The on-board equipment of the secondary surveillance radar (SSR) is called... course indicator. transponder. interrogator. decoder.
What is the difference between primary and secondary radar? The pulses of a primary radar are variably pulse-modulated,
the pulses of a secondary radar are statically amplitude-modulated The pulses of a primary radar are variably amplitude-modulated,
the pulses of a secondary radar are statically pulse-modulated The primary radar is displayed on a computer screen,
the secondary radar on a radar strip The pulses of a primary radar are reflected by the aircraft's surface,
the pulses of a secondary radar system are answered by a transponder.
The transponder code in case of hi-jacking is... 7000 7600 7500 7700.
The transponder code in case of a radio communication failure is... 7000 7600 7500 7700.
Which altitude is transmitted by the transponder in mode C? QFE altitude Pressure altitude QNH altitude Radio altitude.
How many satellites are necessary for a precise and verified three-dimensional determination of the position? 2 3 4 5.
When using a GPS for tracking to the next waypoint, a deviation indication is shown by a vertical bar and dots to the left and to the right of the bar.
What statement describes the correct interpretation of the display? The deviation of the bar from the center indicates the track error as angular distance in degrees; the scale for full deflection depends on the operating mode of the GPS. The deviation of the bar from the center indicates the track error as angular distance in degrees; the scale for full deflection is +-10°. The deviation of the bar from the center indicates the track error as absolute distance in NM; the scale for full deflection is +-10 NM. The deviation of the bar from the center indicates the track error as absolute distance in NM; the scale for full deflection depends on the operating mode of the GPS.
What is meant by the term "terrestrial navigation"? Orientation by ground celestial object during visual flight Orientation by ground features during visual flight Orientation by GPS during visual flight Orientation by instrument readings during visual flight.
What ground features should preferrably be used for orientation during visual flight? Border lines Farm tracks and creeks Power lines Rivers, railroads, highways.
