Flashing requirements of the aircraft warning lights
Synchronous flashing and sequential flashing are the two flashing methods of aviation obstruction lights. As a special civil airport lighting, aviation obstruction lights are limited by relevant standards and specifications in terms of production technology, installation options, and flashing methods.
1. Synchronous flash
All lamps of the obstruction light lighting system composed of type B medium intensity, type A medium intensity or type A high-strength aviation obstruction lights or obstruction light lighting system composed of type A medium intensity or type A high intensity obstruction lights flash in sequence The difference should not be more than 1/60 second.
2. Sequential flash
Sequential flash should meet the following conditions:
1. The obstruction light system of the sign catenary supporting structure composed of B-type high-intensity, A-type medium-intensity or B-type medium-intensity obstruction lights shall flash in sequence;
2. The system should install three layers of obstruction lights near each supporting structure: one layer is close to the top, one layer is at the height of the bottom or the low point of the catenary, and one layer is between the two;
3. The order of flashing should be middle layer, top layer, bottom layer;
