CPL Aircraft General Knowledge 4

Question 1

The main bus bar in an aircraft electrical system serves to:

Accepted Answer

Distribute electrical power from sources to all electrical loads

Answer

Convert alternating current to direct current for avionics

Answer

Regulate voltage output from the alternator

Answer

Store electrical energy for engine starting

Question 2

An ammeter showing a DISCHARGE in flight with the engine running most likely indicates:

Accepted Answer

Alternator output is insufficient to meet current electrical demands

Answer

The battery is fully charged and not accepting current

Answer

Normal operation — slight discharge is expected during high-load phases

Answer

The voltage regulator is maintaining proper system voltage

Question 3

Transponder Mode C provides ATC with which information?

Accepted Answer

Aircraft identification code and pressure altitude

Answer

Aircraft identification code only

Answer

Aircraft position derived from radar only

Answer

Aircraft position, identification, and groundspeed

Question 4

DME distance displayed in the cockpit represents:

Accepted Answer

Slant range (line-of-sight distance) from aircraft to station

Answer

Horizontal ground distance to the station

Answer

Great circle route distance to the station

Answer

True airspeed-adjusted range to the station

Question 5

Which transponder squawk code indicates lost communications (NORDO)?

Accepted Answer

7600

Answer

7500

Answer

7700

Answer

1200

Question 6

When a VOR CDI needle deflects to the right with a TO flag displayed, the pilot should:

Accepted Answer

Turn right — the selected course is to the right of the aircraft's position

Answer

Turn left — the station is to the left of the current course

Answer

Maintain heading — the aircraft is on the correct course

Answer

Reverse course — a TO flag with right deflection means the aircraft is past the station

Question 7

Upon receiving an autopilot disconnect warning, the pilot should FIRST:

Accepted Answer

Immediately take manual control and verify aircraft attitude and course

Answer

Reduce airspeed below maneuvering speed before assuming manual control

Answer

Engage the secondary autopilot mode to maintain control

Answer

Ignore it briefly to confirm the autopilot has actually disconnected
