Hello dude i am also newbie here. Its quite interesting forum. Regarding the information on flights , this forum is the best one which i have ever seen. It would be better to have a video conferencing tool in flight to check the pilot position while on running...
What do you say??
Thanks, Can you answer my question!
Q1 , Typically around 3,500 - 4,000hrs per year , depending on the operator and its route network . Some will be lower , others higher.
Q2 ETOPS , I would suggest the 'maintenance' is the same , but the procedures and practices for ETOPS operations are different. I suggest you start with EU-OPS subpart D. (just goggle it). I cannot think that any airline operating an A330, would be operating the aircraft to a non ETOPS standard.
Many kind thanks for your informative reply, i'm a little surprised at your answer, i was told that airlines only make money by having their planes in the sky and time on the ground was loss making.
I'll Google the 2nd part as advised.
As I said it can be higher Maybe upto 5,000 hrs , but this will depend on how optimised an airlines schedule is . A lot of airports have night time curfews or simply passenegrs don't want or need a service at 2.00 am , so an aircraft arriving late evening will not be used again until the next day . Aircraft need refuelling , Catering , Cleaning and Maintenance . Also airlines choose to offer flights at the times which passengers want them for certain markets ,or to link with other services . Depending on the routes served, frequency of service , flight lengths and time zones, optimum efficency is not always possible . Airlines will also manage the fleet hours , trying to spreading the hours evenly across its fleet .
Thanks again, you obviously have a better understanding than I. How long would an aircraft remain serviceable! I believe there are some 747's that are over 20 years old still being used by British Airways.
Your quite right BA (and other airlines) have B747-400s that were delivered back in 1989 . Some are now parked in storage , but a number are still operational . To answer your question the economic life of an airliner is a combination of flying hours and cycles (take offs and landings) Longhaul aircraft like the B747 can reach 100,000 hrs because the ratio of flying hours to cycles is high. Shorthaul types tend to have higher cycles and lower hours. Much of the high cost maintenance events occur based on cycles. Simply when the real big $$ maintenance events come up as the aircraft reaches the cycles and hours required to have certain madatory checks and repairs , The aircraft simply ceases to be economic to operate any longer . A high hour / high cycle B747 facing a multi million dollar 'D' Check will be at high risk of being parked in the current economic climate. There are a number of B747-200F freighters that are 30 years old still flying where the operators are clearly still finding it more economical to continue operating them than buy younger aircraft.
