In the interest of safety if flashing lights fitted

This preview shows page 14 - 17 out of 38 pages.

In the interest of safety, if flashing lights fitted to an aeroplane adversely affect any performanca of duty (i.e. reflected flash from cloud at night) or causes harmful dazzle to an observer, the pilot is permitted to switch lights off or reduce their intensity. Lights must be switched on: a. In flight at night. b. In flight by day (anti-collision lights). c. When taxiing or parked on the Manoeuvring Area at night. d. When aircraft are stationary on the apron or Maintenanca Area with engines running if fitted by day and by night (anti-collision lights). Gliders. Gliders at night must either display standard lights or a steady red light visible from all directions. 34

CHAPTER 2: RULES OF THE AIR (ICAO) Free Balloons. Free balloons at night must display a steady, red, omni-directional light suspended below the basket. Airships. An airship must show standard navigation lights but in addition must display an anti-coilisian light and a white nose lig ht showing through 11 o o from straight ahead (see Figure 2.17). Failure of Navigation and Anti-Coilisian Lights. On the ground, if an aircraft suffers a failed lig ht that is required to be displayed at night and which is not immediately repairable, the aircraft must not fly. Figure 2. 17 Airship Navigation Lights. If any light fails at night, when airborne, the aeroplane should be landed as soan as is safely possible. The pilot may continue the flight only if authorised to do so by an ATC Unit. If an anti-coilisian light fails during the day, the aeroplane may continue its flight providing the light is repaired at the first opportunity. Collision A voidance at Night. A collision risk between aircraft is present if: a. aircraft are operating at or near the same altitude. b. the aircraft are converging and the relative bearing between aircraft is constant. When the commander of an aircraft observes a light (or lights) of anather aircraft at the same altitude, he must decide whether or not a collision risk exists. If there is no risk of collision, no change of heading or speed is needed. If a collision risk exists, the pilot must first decide which aircraft has right of way in accordanca to the Rules of the Air and then take what avoiding action is necessary. A pilot must not insist on his priority if to do so would cause ariskof collision. Collision Risk & Right of Way. If a collision risk exists and a pilot has right of way, there is no requirement for the pilot to change heading or speed, but he must watch the other aircraft very closely to ensure that it takes avoiding action. Remember: A pilot must not fly under or over anather aircraft or cross ahead of it unless well clear. Speed or altitude should not be changed unless such action is necessary to avoid immediale danger. 35

CHAPTER 2: RULES OF THE AIR (ICAO) There are a number of simple rules for the pilot to observe, and a number of rhymes which may help him remember the rules: If you see a RED lig ht on your RIGHT and it remains on a constant relative bearing to you, take avoiding action!
