Control of Aircraft 17
Air Traffic Advisory Service
17.43Establishment and Objective. The Air Traffic Advisory Service is defined as a service provided within advisory airspace (class F) to ensure separation between aircraft operating on IFR flight plans. In practice, this service is established in response to a request where the establishment of a full ATC service has not been determined. In other words, it is a temporary arrangement pending a decision on whether or not a full ATC service is required. The objective is to make information on collision hazards more effective than it would be in the provision of a flight information service only. It is provided to IFR flights in advisory airspace or on advisory routes.
17.44Operation. The Air Traffic Advisory Service does not afford the degree of safety and does not assume the same responsibilities as a full ATC service. To this end clearances are not issued and only advice or suggestions are offered by the ATCOs. An IFR flight electing to use the service is expected to comply with the same procedures as would be in force in CAS, except that Flight Plan changes are not subject to clearance. All IFR flights flying in class F airspace are required to file Flight Plans. Traffic electing to use the advisory service will receive an ‘acknowledgement’ of the submission of the Flight Plans only. IFR flights crossing an advisory route are required to do so at ‘right angles’ to the route direction at a level appropriate to the semi-circular rule.
Aircraft Emergencies
17.45 Use of SSR. Use of the reserved SSR codes is the most expeditious means of indicating a situation where an aircraft requires assistance. Clearly, the aircraft must be flying in an area where radar is used for ATC, and in this may be a factor of altitude. Even outside of radar control areas there are military facilities and mobile units that can interrogate and receive SSR information which can assist the alerting service to provide the necessary assistance. The reserved codes are:
• Mode A code 7700 |
Emergency |
|
• |
Mode A code 7600 |
Radio failure |
• |
Mode A code 7500 |
Unlawful Interference |
Additionally:
• Mode A code 7000 Conspicuity code for an aircraft operating in an area where a radar service is available but the aircraft is not in receipt of the service (commonly referred to as VFR conspicuity)
• Mode A code 2000 An aircraft is operating in an area where a radar service is not available but will be entering an area where a radar service is available and will be requesting that service (this is used for eastbound NAT traffic east of 30W that intend entering the Scottish UIR).
17.46 Aircraft Already Identified. If a pilot is already in receipt of a radar service and has been identified by the use of a discrete SSR code, selection of a reserved code to indicate a state of emergency may delay the application of the assistance. In this case the allocated Mode A code should be retained.

17 Control of Aircraft
17.47ATC Contact in an Emergency. In an emergency pilots can expect to be contacted by ATC on 121.5 MHz or, as a back-up, on the inter-pilot air-to-air frequency 123.45 MHz.
17.48Emergency Descent. If an aircraft suffers a pressurization failure at altitude, the rules require the aircraft to be descended to an altitude where oxygen in the air supports life. In the event, ATC will broadcast a warning to aircraft in the vicinity of a descending aircraft. The pilot of the descending aircraft should attempt to broadcast the aircraft altitude at intervals to assist other aircraft to avoid a collision.
17.49Fuel Jettison. In certain circumstances, it may be necessary to reduce the mass of the aircraft to maximum landing mass as soon as possible by dumping as much fuel as is required. All aircraft which have a maximum take-off mass greater than the maximum landing mass are required to have a fuel jettison system. If the aircraft is flying in CAS, before commencing fuel jettison, the controlling ATCU is to be informed. The route over which the fuel is to be jettisoned should be clear of towns, preferably over water and clear of areas where thunderstorm activity has been reported or is expected. The level at which the jettison takes place is to be not lower than 6000 ft. This will allow the fuel in aerosol form to evaporate before reaching the ground. The ATCU is to be advised of the duration of the operation.
17.50Strayed and Unidentified Aircraft. A strayed aircraft is one that has deviated significantly from its intended track or reports that it is lost, whereas an unidentified aircraft is one of which the ATCU is aware but the identity is not known.
