Question 1

GR 3.6.5 Communications

Answer 1

A controlled flight must maintain continuous communication when in movement
Except when becoming part of aerodrome traffic at a controlled aerodrome

Question 2

What are the 6 standard actions in a failure procedure

Answer 2

1. Check freq and volume and settings
2. Attempt to connect with other ATSU and aircraft or try 121.5 freq

Question 5

If failure in radar environment

Answer 5

The exact same procedure as non radar but set a timer for 7mins instead

Question 6

Answer 6

Rejoin current fpl prior to reaching next CRP
Then steps 5,6,7 as usual

Question 7

What is EAT

Answer 7

Expected approach time, the time when ATC expects an aircraft following a delay to leave the holding pattern and complete approach for landing

Question 8

ETA…

Answer 8

Expected time of arrival, the time stated on the fpl of when an aircraft will leave the holding pattern to complete approach

Question 10

GR3.7 Unlawful Interference (UI)

Answer 10

An aircraft that is the subject of unlawful Interference should try to notify the nearest ATSU that…
Any significant circumstances
The fact they are being UI
Deviations from fpl that will occur because of the UI

Question 11

ICAO policy on interception

Answer 11

It should only be undertaken as a last resort
Visual signals should be correctly employed and understood through civil and military aircraft internationally

Question 13

If an interception is undertaken then it will be limited to determining the aircraft identity unless its necessary to…

Answer 13

1. Return aircraft to original fpl
2. Direct it a away from national boundaries of airspace
3. Guide it away from a dangerous or restricted area
4. Instructed to land at a specific aerodrome

Question 14

An aircraft which has been intercepted should…

Answer 14

1. Follow all instructions given by intercepting aircraft
2. Notify ATSU
3. Attempt to establish communication on 121.5
4. If equipped with an SSR transponder then set Mode A, Code 7700

Question 15

Phrases for interception 1

Answer 15

KOL SA-IN …what is your callsign
FOL-LO … follow me
DEE-SEND … descend for landing
YOU-LAAND … land at this aerodrome
PRO-SEED … you may proceed

Question 16

Phrases for interception 2

Answer 16

VILL-CO … understood, will comply
KANN NOTT … unable to comply
REE-PEET …repeat instruction
AM LOOST
MAYDAY
HII - JACK

Question 17

Signals initiated by intercepting aircraft, you should return all signals if understood apart from abrupt turn

Answer 17

Rocking and flashing lights = you’ve been intercepted follow me.
An abrupt manœuvre away. = you may proceed
Rocking the aircraft = understood
Lowering landing gear = land here

Question 18

ICAO principles for interception

Answer 18

Practise interception should not occur
Navigational guidance shall be given if radio comms can be established
If required to land then the aerodrome must be suitable for type of aircraft
Contracting states must publish a standard method to avoid any hazard
Must refrain from use of weapons

Question 20

Rules for flight under VFR

Answer 20

They shall not take off or land in a control zone or enter a ATZ or pattern when…
1. The ceiling is less than 1500ft
2. Ground visibility is less than 5km
Unless cleared for special VFR by ATCU
VFR flights shall NOT be operated above FL200 or at great speeds

Question 21

A special VFR flight parameters are

Answer 21

When cleared to fly within a control zone in met conditions below VMC

1. Ceiling not less than 600ft
2. Minimum vis is 1.5km
3. Remain insight of ground
4. Max speed is 140kts

Question 22

Ceiling is…

Answer 22

A broken or overcast level with clouds that cover more than half the sky
4 - 8 octas

Question 23

VFR height rules

Answer 23

1. Over congested areas no less than 1000ft over highest obstacle
2. Over uncontested areas no less than 500ft from highest obstacle
3. Radius of 600m from aircraft
4. No VFR considered above FL290 in RVSM airspace

Question 24

What is RVSM

Answer 24

Reduced Separation Vertical Minima
Extends from Fl290 to Fl410
It halves all separations. Eg. From 2000ft to 1000ft

Allows for more aircraft in an airspace safely

Where no minimum flight altitude has been established then.. 1000ft ab highest obstacle 2000ft over mountainous areas or high terrain The highest obstacle over 8km away

Question 27

When changing from IFR to VFR flight then...

Answer 27
