M1, S1, C8 - Diversion Procedures Flashcards
Aircraft may divert from their planned destination to another aerodrome on the initiative of…
…the pilot or as requested by the appropriate authority on the ground.
Diversions will normally be made for the following reasons:
(1) When the weather at the planned destination is reported to be below the minima prescribed by an Aircraft Operator for their aircraft;
(2) When obstructions on the landing area, which constitute a hazard to aircraft landing, cannot be cleared within a reasonable period;
(3) The failure of airborne equipment;
(4) The failure of essential ground aids to landing in circumstances which would require their use;
(5) Unacceptable delay due to congestion of air traffic;
(6) The closure of the aerodrome of destination.
Who is responsible for decisions regarding the availability of the aerodrome?
The Aerodrome Operator
The pilot of an aircraft is primarily responsible for its safety, therefore he will normally decide whether he can or cannot effect a safe landing at a given aerodrome. He will normally be aware of weather conditions at his planned destination and alternate aerodromes, thus whenever he considers a diversion to be necessary, he will…
…make his intention known to an ATC unit and request further clearance. His decision will normally be in accordance with the minima prescribed by his company
When specifically requested by the pilot that his company or a nominated addressee be advised of his diversion the controller is to pass this message to the ATSU at either:
(1) the original destination; or
(2) the aerodrome nearest to the original destination.
An ATSU receiving such a message is to pass it to the addressee
When, for traffic reasons, a controller considers it advisable to divert an aircraft he shall consult…
…the Aircraft Operator.
The controller and the aircraft operator shall decide between them the diversion aerodrome. The request to divert shall be passed to the pilot together with reasons for diversion, an ATC clearance and any further instructions
In cases of emergency it may be necessary for an aircraft to be diverted without prior consultation with the Aircraft Operator. In this event, the controller shall…
…pass the message to the pilot expressed as a request and inform the Aircraft Operator as soon as possible. When the operator of the aircraft is not known, the pilot is to be asked to nominate an addressee
On receipt of the diversion message the pilot will…
…acknowledge and comply with the request or give his reason for non-compliance.
If he decides against diversion, permission to attempt a landing shall not be refused unless the aerodrome has been closed by the Aerodrome Operator
All information concerning the diversion of military aircraft is to be passed to…
…D&D
Except in an emergency, aircraft shall not be diverted to an RAF or USAF aerodrome without the prior approval of…
…D&D
Aircraft from the CIS, even though in an emergency, must not be diverted to RAF aerodromes except with the agreement of…
…D&D.
In all other cases of emergency, controllers should, whenever possible, consult D&D before arranging for the aircraft to land at an…
…RAF or USAF aerodrome.
RAF aerodromes that intend to keep open beyond the hours of watch published in the RAF En Route Supplement British Isles and North Atlantic will notify D&D. This information will be available to the civil supervisor if required
