Demo: PPL/H

The aircraft is on radial 234 because radials are measured from the station outward. The other options (246, 060, 066) represent different directions that do not match the aircraft's indicated position.

The range of a VOR depends on the altitude of the transmitter and receiver, as VORs operate on line-of-sight. Daylight interference, ground wave multipath, and reflected sky waves do not significantly affect VOR range.

DME measures distance by timing how long a radio signal takes to travel to the ground station and back. Phase comparison, laser measurement, and Doppler are not used in DME.

DME shows the slant range, which is the direct line distance between aircraft and ground station. Ground distance is incorrect as it ignores altitude. GNSS distance and radial distance are different measurements and not what DME displays.

Correct: Primary radar pulses are reflected by the aircraft, secondary radar pulses are answered by a transponder. The other options incorrectly describe modulation types or display methods, not the actual operational difference.

The transponder code 7600 indicates radio communication failure. 7000 is for VFR flights, 7500 signals hijacking, and 7700 is for emergencies. Only 7600 is used for lost radio contact.

'Knowledge' is correct because understanding aviation principles, regulations, and procedures is part of knowledge. 'Skills' are about practical execution, 'Attitudes' are about mindset, and 'Experience' is about accumulated practice.
