![]() Logo lights illuminate the tail of the aircraft for better recognition of an aircraft company at night. It is also a clear signal for the air traffic controller to realize if the pilot believes he is cleared to enter a runway. Several national regulations recommend turning on the strobes whenever the aircraft intends to cross or enter a runway for takeoff. On large aircraft, an additional strobe may be found on the tail of the aircraft. It is aimed for an early detection of aircraft from any direction. Strobe lights are powerful flashing white lights on the wing tip of the aircraft. Several national regulations recommend turning on the beacon whenever the aircraft intends to start its engine(s) or to be towed in order to notify the people around the aircraft. This light is omnidirectional and plays another major role in preventing collisions. ¶ Anti-collision / beacon lights ¶ DescriptionĪnti-collision or beacon lights are a red or white flashing lights on the top or on the bottom of the aircraft. The rule of good practice is to switch on the navigation lights as soon as the pilot will switch on any source (ground power unit (GPU), auxiliary power unit (APU), battery) of electrical energy inside the aircraft. If a white light is seen, this aircraft is seen from the rear, flying away: collision is remote.If a white and a green light are seen, this aircraft fly away from left to right: collision is possible.If a white and a red light are seen, this aircraft fly away from right to left: collision is possible.If a green light is seen, this aircraft will fly from left to right: collision is possible.If a red light is seen, this aircraft will fly from right to left: collision is possible.If a green and a red light are seen, this aircraft is facing us, flying toward us: collision is probable!.Therefore, the following conclusions can be drawn: Since the color is in relation with the direction from which an aircraft can be seen, we can immediately determine the trajectory of any airplanes. Therefore it plays a major role in preventing collisions between aircraft. These lights are used to determine the position and the heading of an aircraft. Refer to the figure below for more visualization. These lights are defined as follow: - A red light located on the left wing tip visible with an angle of 110° from the front of the aircraft - A green light located on the right wing tip visible with an angle of 110° from the front of the aircraft - A white light on the tail of the aircraft visible with a centered angle of 140° ¶ Lights Description ¶ Navigation / position lights ¶ Regulations and descriptionĪll aircraft must be equipped with navigation lights. We will review their types, their use and their aspects. ![]() This documentation will define the regulatory lights that any aircraft should be equipped with. ![]()
