How long can the plane fly?

The life of an airplane usually has three indicators. According to the life of flying years, the service life of an aircraft is about 25 to 30 years. 10 civil aircraft is in the prime of life, but it will be inferior to the new passenger aircraft in comfort and fuel economy, so airlines will generally replace it with a new passenger aircraft and convert the old passenger aircraft into a cargo aircraft.

There are three main indicators that determine the retirement time of an aircraft: the number of take-off and landing, the number of flight hours and the number of flight years.

The take-off and landing life of trunk aircraft is about 40 thousand times, and that of regional aircraft can reach 60 thousand times; The flight duration of most aircraft is about 60,000 hours; The flight life, that is, the age of the aircraft is about 25-30 years. Among the three indicators, the first is the first, and the number of take-off and landing has the greatest impact on the life of the aircraft.

At present, the average service life of civil aviation aircraft in the world is 10 years, but in terms of performance, it is far from being scrapped. It is not a problem to fly for 30 years or even longer to maintain a good flight condition through regular maintenance.

Of course, it is not necessarily impossible to fly when the plane is retired. Whether it can be retired depends on the airline's development plan. According to the changes of the fleet's asset value, comfort, dispatch rate and maintenance cost, a comprehensive evaluation is made to determine whether to dispose and transfer it in advance.
