Q

When homing to an Non Directional Beacon (NDB) allowing for 10 degrees port (left) drift, you can confirm maintaining track when the HDGºM is steady and the Automatic Direction Finder (ADF) needle indicates (350ºR / 010ºR). If the needle starts to move in an anticlockwise direction, you are (over / under) allowing for drift.

A

350ºR; over

Q

When tracking away from an Non Directional Beacon (NDB) on a steady HDGºM allowing for 5 degrees starboard (right) drift, the Automatic Direction Finder (ADF) needle should remain on (175ºR / 185ºR). If the needle starts to move in an anticlockwise direction, you are (over / under) allowing for drift.

Q

When you are uncertain of your position you turn on the Very High Frequency Omni Range (VOR), you select the appropriate frequency, you …….. the VOR station, you turn the …….. knob until the …….. moves to the (centre / full deflection) position and the window shows (FROM / TO).

A

identify; Omni Bearing Selector (OBS); Course Deviation Indicator (CDI); centre; FROM

17
Q

You are flying inbound on the required radial to a Very High Frequency Omni Range (VOR) station with TO in the window. If the drift correction is 6 degrees port (left), you expect the Course Deviation Indicator (CDI) to show (two dots left / two dots right / centre position).

A

centre position

18
Q

When you fly outbound from a Very High Frequency Omni Range (VOR) station on a certain radial, the window should show (TO / FROM) and if the Course Deviation Indicator (CDI) moves off-centre to the right - you should carry out a (left / right) turn to return to the radial.

A

FROM; right

19
Q

If you fly towards a Very High Frequency Omni Range (VOR) station with FROM in the window and the Course Deviation Indicator (CDI) shows a left deflection, you should turn (left / right) to regain the radial.

A

right

20
Q

While tracking out from a Very High Frequency Omni Range (VOR) station on R170, your heading is 175ºM, Omni Bearing Selector (OBS) is set to 170, the window shows FROM, and the Course Deviation Indicator (CDI) shows left two dots (the circle + one dot). What radial are you on at this time.

A

radial 174

21
Q

While tracking in to a Very High Frequency Omni Range (VOR) station on R240, your heading is 058ºC, deviation is 2ºE, Omni Bearing Selector (OBS) is set to 060, the window shows TO, and the Course Direction Indicator (CDI) shows right three dots (the circle plus two dots). What radial are you on at this time?

A

radial 246

22
Q

Shortly before over-heading the Very High Frequency Omni Range (VOR) station, the Course Direction Indicator (CDI) will …….., when overhead the window will …….., and when you have passed the overhead, the window will show …….. and the CDI will be …….. if you are on the required radial.

A

start to swing left to right; fluctuate OFF to FROM; FROM; centered

23
Q

The fundamental purpose of Distance Measuring Equipment (DME) in an aircraft is to determine the …….. of the aircraft from the ground station.

A

distance

24
Q

What is the principle of operation of a Distance Measuring Equipment (DME) transponder?

A

measuring the difference between the time an aircraft sends a signal to the ground transponder, and the time when it receives a reply from the ground station transponder.

25
Q

The range of reception of Distance Measuring Equipment (DME) signals is affected by (airspeed / altitude / air density) - it can be improved by flying (faster / slower / higher / lower).

A

altitude; higher

26
Q

Mode error can occur when the Global Positioning System (GPS) equipment has …….. function keys.

A

27
Q

When Receiver Autonomous Integrity Monitoring (RAIM) warning is displayed it indicates that the minimum level of navigation accuracy (is / is not) provided by the GPS equipment.

A

28
Q

When planning to use a portable GPS unit which cannot be connected to the electrical supply of the aircraft, the pilot should have available a …….. ……..

A

spare battery

29
Q

When a pilot asks for radar assistance when experiencing navigation difficulties, (the pilot / ATC) is responsible for navigation and (the pilot / ATC) is responsible for the maintenance of safe altitudes.

A
