Barrier:
UP – the barrier is in the raised position and ready for an engagement.
DOWN – the barrier is in the lowered position, but could be raised on request.
UNSERVICEABLE – the barrier system is not available.
The position of a cable, in distance from the approach end threshold rounded to
nearest 100 ft is to be given to aircraft unfamiliar with the aerodrome. When barrier
position and/or cable state is as published in FLIPs, reference to them is normally
omitted to aircraft based at the aerodrome and reference to cable state is normally
omitted to visiting aircrew that are familiar with the aerodrome. A pilot may require a
change to arrestor system positions and will normally try to warn of an imminent
engagement.
An airborne aircraft requesting an engagement will provide as much of the following
information as possible:
• Callsign and type of aircraft.
• Nature of emergency and which arresting system he is intending to engage.
• Estimated time to landing in minutes.
In addition, except for short or no notice engagements, the pilot should report
"Hook Down" as part of the final call. If the controller does not receive the hook
down call, a check will be requested:
On receipt of a request from an airborne aircraft, the controller is to:
• advise the pilot of the serviceability state of the preferred arresting system;
• if necessary, advise of the time that the arresting system will become available;
• request fuel remaining, and once the engagement has occurred, obtain the aircraft
weight and engagement speed;
• pass normal landing information;
• alert the Crash/Rescue Crew to an appropriate readiness state.
After a successful engagement, the pilot will not taxi the aircraft until the ground/
recovery party has signalled the aircraft can commence taxi and a clearance to do so
has been obtained from ATC.
Following an engagement, the runway shall be declared "black" until the team leader
of the recovery crew ensures that the runway has been vacated. The following
conditions are to be satisfied prior to informing ATC:
• No personnel, equipments or vehicles are within the confines of the runway or
requiring to cross the runway to vacate the area.
• The arresting system has been returned to a serviceable state, a battery position,
removed from the runway or declared as unserviceable.
The ATC Supervisor will then declare the runway open.
