Communication Failure Procedure (set the transponder to Mode A Code 7600)

VMC

a.     Continue to fly in visual meteorological conditions;

b.     Land at the nearest suitable aerodrome; &

c.     Report its arrival by the most expeditious means to appropriate air traffic control unit.

IMC or when conditions are such that it does not appear feasible to complete the flight in VMC

a.     Maintain the last assigned speed & level, or minimum flight altitude if higher, for a period of 20 minutes following the aircraft's failure to report its position over a compulsory reporting point & thereafter adjust level & speed in accordance with the filed flight plan;

b.     Proceed according to the current flight plan to the appropriate designated navigation aid serving the destination aerodrome &, when required to ensure compliance with c\ below, hold over this aid until commencement of descent;

c.     Commence descent from the navigation aid specified in b. at, or as close as possible to, the expected approach time last received & acknowledgement; or, if no expected approach time has been received & acknowledgement, at, or as close as possible to, the estimated time of arrival resulting from the current flight plan;

d.     Complete a normal instrument approach procedure as specified for the designated navigation aid; &

e.     Land, if possible, within thirty minutes after the estimated time of arrival specified in c. or the last acknowledged expected approach time, whichever is later

Interception & Responding Procedures (set the transponder to Mode A Code 7700)

An aircraft which is intercepted by another aircraft shall immediately:

a.     Follow the instructions given by the intercepting aircraft, interpreting & responding to visual signals shown below;

b.     Notify, if possible, the appropriate air traffic service unit;

c.     Attempt to establish radio communication with the intercepting aircraft/ unit, by making a general call on the emergency frequency 121.5 MHz, or 243 MHz

INTERCEPTING Aircraft Signals

MEANING

INTERCEPTED Aircraft Responds

MEANING

Series 1

Day or Night – Rocking aircraft & flashing navigation lights @ irregular intervals from a position slightly above & ahead, & normally to the LEFT of, the intercepted aircraft, & after acknowledgement, a slow level turn, normally to the LEFT onto the desired heading.

You have been intercepted.

Follow me.

Day or Night –

Rocking aircraft, flashing navigation lights @ irregular intervals & following.

Understood.

Will Comply

Series 2

Day or Night – A abrupt breakaway maneuver from the intercepted aircraft consisting of a climbing turn of 90 degrees or more without crossing the line of flight of the intercepted aircraft.

You may

proceed.

Day or Night –

Rocking the aircraft.

Understood.

Will Comply

Series 3

Day or Night – Lowering landing gear, showing steady landing lights & overflying runway in use.

Land @ this

aerodrome

Day or Night –

Lowering landing gear, showing steady landing lights & following the intercepting aircraft & after overflying the runway in use, proceeding to land

Understood.

Will Comply

INTERCEPTED Aircraft Signals

MEANING

INTERCEPTING Aircraft Responds

MEANING

Series 4

Day or Night – Raising landing gear & flashing landing lights while passing over runway in use, & continuing to circle runway in use.

Aerodrome you have designated is inadequate.

Day or Night –

If it is desired that the intercepted aircraft follow the intercepting aircraft to an alternate aerodrome, the intercepting aircraft raises its landing gear.

If it is decided to release the intercepted aircraft, the intercepting aircraft uses Series 2 signals for intercepted aircraft

 

Understood Follow me.

 

 Understood

You may

proceed.

Series 5

Day or Night – Regular switching on/ off all available lights but in such a manner as to be distinct from flashing lights

Cannot comply

Day or Night –

Use Series 2 signals for intercepting aircraft.

Understood

Series 6

Day or Night – Irregular flashing of all available lights

In distress

Day or Night –

Use Series 2 signals for intercepting aircraft.

Understood
