INTERNATIONAL CIVIL AVIATION ORGANIZATION (ICAO) 8.4 SEARCH AND RESCUE SIGNALS

8.4.2.1 The following maneuvers performed in sequence by an aircraft mean that the aircraft wishes to direct a surface craft towards an aircraft or a surface craft in distress:

a.circling the surface craft at least once;

b.crossing the projected course of the surface craft close ahead at low altitude and:

1. rocking the wings; or

2.opening and closing the throttle; or

3.changing the propeller pitch.

NOTE: Due to high noise level on-board surface craft, the sound signals in (2) and (3) may be less effective than the visual signal in

(1) and are regarded as alternative means of attracting attention.

c.heading in the direction in which the surface craft is to be directed.

Repetition of such maneuvers has the same meaning. (Annex 12, Appendix A, 1.1)

8.4.2.2 The following maneuver by an aircraft means that the assistance of the surface craft to which the signal is directed is no longer required:

–crossing the wake of the surface craft close astern at a low altitude and:

a.rocking the wings; or

b.opening and closing the throttle; or

c.changing the propeller pitch.

(Annex 12, Appendix A, 1.2)

8.4.3.4Air-to-ground Signals

8.4.3.4.1 The following signals by aircraft mean that the ground signals have been understood:

a.during the hours of daylight:

–by rocking the aircraft’s wings;

b.during the hours of darkness:

–flashing on and off twice the aircraft’s landing lights or, if not so equipped, by switching on and off twice its navigation lights. (Annex 12, Appendix A, 3.1)

8.4.3.4.2 Lack of the above signal indicates that the ground signal is not understood. (Annex 12, Appendix A, 3.2)

COMMUNICATIONS FAILURE

EMERGENCY SATELLITE VOICE CALLS

FROM AIRCRAFT

For aircraft flying in Algiers FIR/UIR, in the event that all other means of communication have failed, dedicated satellite voice telephone numbers for Algiers ACC have been programmed into the aeronautical Ground Earth Stations of the Inmarsat Signatories. The allocated airborne numbers for use via the aircraft satellite voice equipment are as follows:

Algiers ACC

Tel: 00871763645324

00871763645325

It must be emphasized that these numbers are for emergency only, when all other airborne means of communication with the appropriate ATS unit have failed.

AIRCRAFT DEPARTING VIENNA (SCHWECHAT)

The following procedure shall be observed when experiencing radio communication failure (except for ABLOM, KOVEL, LANUX, MIKOV, SASAL and STEIN departures):

–squawk A 7600 and maintain 5000ft MSL until distance 20 DME FMD;

–then climb to FL120 (or to the filed flight level if below FL120);

–maintain FL120 for a period of 3 minutes, then climb to the cruising level filed in the flight plan.

AIRCRAFT DEPARTING SALZBURG

The following procedures shall be observed when experiencing radio communication failure:

–LIMRA departures:

•squawk A 7600 and maintain FL60 until distance 13 DME SBG;

•then climb to FL120;

•maintain FL120 for a period of 3 minutes, then climb to the cruising level filed in the flight plan.

–RASTA departures:

•squawk A 7600 and maintain FL100 until distance 12 DME SBG;

•then climb to FL120, or to the cleared flight level;

•maintain FL120, or the cleared flight level, for a period of 3 minutes, then climb to the cruising level filed in the flight plan.

ICAO DIFFERENCES OR STATE SPECIAL PROCEDURES

# GENERAL

In general, the Emergency, Unlawful Interference, Communications Failure, Interception and Search and Rescue procedures are in conformity with the Standards, Recommended Practices and Procedures in ICAO Annexes and Documents.

COMMUNICATION FAILURE

RADAR FAILURE

In the event of Radar failure or loss of radar identification, instruction will be issued to the pilot to increase separation up to the values prescribed for flights without radar control:

-at least 10 minutes for aircraft proceeding at the same level along the same route;

-at least 20 minutes at the moment of crossing when crossing the same or opposite direction flight level occupied by another aircraft;

-at least 3 minutes when performing approach manoeuvres in control zone.

RADIO FAILURE

The Radar controller will establish whether the aircraft radio receiver is working by instructing the pilot to carry out turns, if turns are observed the radar controller will continue to provide radar service.

If the aircraft’s radio is completely unserviceable, the pilot should carry out the procedures for communication failure in accordance with ICAO. If radar identification has already been established, the radar controller will vector other identified aircraft clear of its track until such time as the aircraft leaves the radar cover.

ICAO DIFFERENCES OR STATE SPECIAL PROCEDURES

GENERAL

In general, the Emergency, Unlawful Interference, Communications Failure, Interception and Search and Rescue procedures are in conformity with the Standards, Recommended Practices and Procedures in ICAO Annexes and Documents.

EMERGENCY RUNWAY PROCEDURE

Due to the physical restrictions imposed on the traffic movement of the Bahrain (Int’l) airfield during the operation of the emergency runway, the use of such runway shall strictly be allowed during emergency periods only.

Aircraft intending to land on the emergency runway shall, after being well-established on the final approach segment on an instrument approach for runway 30R or runway 12L, attempt to establish visual contact with the emergency runway at a distance of not less than 4NM from the threshold, if the emergency runway is visible, the pilot may execute a visual side-step manoeuvre and continue a visual approach to the emergency runway. If no visual contact has been made with the emergency runway before crossing 4NM on final approach segment, the pilot shall initiate a missed approach as per the main runway procedures, inform air traffic control and follow ATC instructions.

If a normal landing can not be made after the side-step manoeuvre has been executed and the aircraft is within 4NM in line with final approach leg of the emergency runway, the pilot shall:

a.For emergency RWY 30L: Climb 2500ft on track 301°, when level, turn right to rejoin the hold or as instructed by ATC.

b.For emergency RWY 12R: Climb 2500ft on track 120°, when level, turn left to rejoin the hold or as instructed by ATC.

COMMUNICATIONS FAILURE

In VMC: ICAO Procedure.

In IMC: ICAO Procedure, supplemented as follows:

DEPARTING AIRCRAFT UNDER RADAR

CONTROL

If departing from Bahrain (Intl) airport on a radar clearance and experiencing complete radio communication failure maintain the last assigned heading and flight level or altitude for a period of 3 minutes after departure or to a distance of 12 DME Bahrain VORDME ‘BAH’ whichever occurs earlier. Thereafter continue according to the current flight plan by routing direct to the first enroute reporting point and climbing to the last acknowledged enroute flight level cleared by ATC.

GENERAL

In general, the Emergency, Unlawful Interference, Communications Failure, Interception and Search and Rescue procedures are in conformity with the Standards, Recommended Practices and Procedures in ICAO Annexes and Documents.

COMMUNICATIONS FAILURE

See EMERGENCY PAGE EE-22, and supplemented as follows:

#After entry into TMA continue flight at last assigned flight level to LOM of destination aerodrome. Descent for approach shall commence not earlier than ETA and landing shall be carried out not later than 30 minutes after ETA.

If radio communication failure appears during final approach and the meteorological conditions are below minimum, pilot-in-command has the right to land under current conditions.

After take-off the pilot-in-command shall operate according to the approach pattern and land at the departure aerodrome under meteorological conditions below minimum. A listening watch on the LOM frequency obtaining ATC instructions and information is necessary.

If meteorological conditions or other reasons do not allow landing at the departure aerodrome, pilot- in-command has the right:

-proceed to the destination aerodrome climbing to the flight level indicated in the FPL according to departure pattern;

-proceed to the alternate aerodrome at the flight level selected by the pilot not below safe

"! flight level.
