The Civil Aviation (Aeronautical Search And Rescue) Regulations, 2017

1. Signals with surface craft (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, but not lower than 500 ft above ground level, and rocking the wings, or opening and closing the throttle, or (i) (ii) (iii) Changing the propeller pitch Due to high noise level on board surface craft, the sound signals in (ii) and (iii) may be less effective than the visual signal in (i) and are regarded as alternative means of attracting attention. (c) heading in the direction in which the surface craft is to be directed. (2) Repetition of such maneuvers has the same meaning. (3) The following maneuvers by an aircraft means that the assistance of the surface craft to which the signal is directed is no longer required: (a) crossing the wake of the surface craft close astern at a low altitude and rocking the wings; or (b) opening and closing the throttle; or (c) changing the propeller pitch. (d) the changing of heading to follow the aircraft.

2. Ground-air visual signal code for use by survivors 26

3. Ground-air visual signal code for use by rescue units.

4. Symbols shall be at least 2.5 metres (8 feet) long and shall be made as conspicuous as possible. Note 1. — Symbols may be formed by any means such as: strips of fabric, parachute material, pieces of wood, stones or such like material; marking the surface by tramping, or staining with oil. Note 2. — Attention to the above signals may be attracted by other means such as radio, flares, smoke and reflected light. 27

5. Air-to-ground signals (1) The following signals by aircraft mean that the ground signals have been understood: (a) during the hours of daylight (i) by rocking the aircraft’s wings; (b) during the hours of darkness: (ii) (iii) flashing on and off twice the aircraft’s landing lights or, if not so equipped, by switching on and off twice its navigation lights. (2) Lack of the above signal indicates that the ground signal is not understood. Dar es Salaam, 20th February, 2017 MAKAME M. MBARAWA Minister for Works, Transport and Communication 28
