What is the difference between primary and secondary radar?

A The pulses of a primary radar are variably amplitude-modulated, the pulses of a secondary radar are statically pulse-modulated B 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 C The primary radar is displayed on a computer screen, the secondary radar on a radar strip D The pulses of a primary radar are variably pulse-modulated, the pulses of a secondary radar are statically amplitude-modulated

Show solution

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 in case of a radio communication failure is...

A 7600. B 7500. C 7000. D 7700.

Show solution

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.

Which component of pilot competence primarily involves understanding aviation principles, regulations, procedures, and operational aspects of aircraft?

A Experience B Skills C Attitudes D Knowledge

Show solution

'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.
