If the gearbox oil is too little oil leakage or the oil is exhausted, the ratio of gasoline to oil is too large, and the lubrication is not good, which is a factor that causes the engine temperature to be high. If the engine temperature is too low, the pilot should be softened to prevent the air from stopping. It is strictly forbidden to pull the ignition charge during flight. The wire should be inspected regularly to prevent corrosion or aging. The spark plug should be inspected every flight hour, and the spark plug should be replaced once every hour. In particular, a single spark plug is used in an engine, which should be noted. The aircraft must have full-time maintenance personnel. Some air station maintenance is done by the pilot, the flight quality is difficult to guarantee, and the safety flight has hidden hidden dangers.
Maintenance personnel are important factors to ensure flight safety and cannot be ignored or omitted. If the engine is parked in the air, it should immediately maneuver the aircraft to slide down and maintain the speed of the bee-type aircraft, and make a forced landing according to the position and flight height of the aircraft. The order of the forced landing of the off-site is more than 50. The forced landing is carried out. () l Turn the aircraft into a downturn, ensure that the speed is selected as soon as possible, and the landing area is flat and the flight commander is reported. In order to judge the wind direction, the slip route is determined according to the height of the aircraft. Visual inspection should normally be a little higher, closing the oil circuit and ignition switch before landing.
The enclosed cockpit should open the canopy. The landing pull height can be slightly higher, and the aircraft is grounded at a slightly larger elevation angle and a smaller speed. When the plane is about to be grounded, the two feet are quickly retracted, the left arm protects the face, and the steering column is pressed to one side. After grounding, quickly get out of the plane, try to protect the aircraft, and report the situation to the superior in time. The height is below the forced landing (l) immediately turns to the down protection rate) to determine the situation in front of the venue. Usually, it should be forced to make a straight line. If there are obstacles, the direction of the landing should be changed in time, but the turning angle is not too large. Land and grounding movements are the same as those with a height of 50 meters or more.
