IFR Navaids - Mock Exam

Pitot pressure can be defined as:

• The sum of prevailing static air and dynamic pressure, which is used to measure

  airspeed.

• The sum of prevailing total pressure and dynamic pressure, which is used to

  measure airspeed.

• The sum of static air and dynamic pressure, which is used to measure true

  airspeed.

• The sum of total pressure and dynamic pressure, which is used to measure true

  airspeed.

How does the airspeed indicator measure speed?

• Dynamic plus static

• Pitot minus static

• Dynamic and static

You try to realign your heading indicator with your compass however it is not responding as fast as usual. What are the possible causes?

• Gimbal rings are over lubricated

• The Bevel ring needs to be tightened to the Bevel gear

• The DI is now spinning horizontally

• The gyro has a low RPM

Compared to Secondary Surveillance Radar (SSR), Primary Surveillance Radar (PSR);

• Requires more power

• Needs an aircraft transponder

• Has better range

• Requires aircraft to have a transponder and PSR is higher powered

What is the maximum range of the Civil Primary Surveillance Radar in New Zealand?

• 150nm

• 256nm

• 80nm

• 60nm

What is the maximum range of the Civil Secondary Surveillance Radar in New Zealand?

• 80nm

• 256nm

• 150nm

• 60nm

What determines the maximum distance for PSR?

• Pulse reoccurrence frequency

• Pulse width

• Pulse band

• Pulse noise

Describe the precautions required when changing codes?

• Change transponder code to 0000 then enter your new code to avoid inadvertently

  squawking 7500, 7600 or 7700.

• It is good practice to turn the transponder onto standby then change, to avoid inadvertently squawking 7500, 7600, 7700.

• Leave it in mode C at all times so ATC don't lose sight of you

• No precautions needed

In regard to Pilot Activated Lighting (PAL).

It is activated by ___ rapid transmissions in ___ seconds.

• 3, 5

• 5, 3

• 4, 6

• 3, 7

What Is the procedure for tuning a VOR?

• CDI for identifying it and make sure you leave on ANT for when you're

  navigating

• Switch it to CDI, you will hear the Very High Frequency morse code

• Tune using the correct frequency and it will show you the VOR station

• Tune frequency, identify morse code and ensure arrow is pointing in a

  rational direction
