What is the difference between aircraft flight hours and flight cycles?
Wiki User

Flying hours are the number of hours that an aircraft has flown (usually from engine start to engine stop). One flight cycle is one flight from take-off to landing.

What is the difference between first flight and introduction in an aircraft?
There is lot of difference between test flight/air test/first flight.
Difference between operating weight and dry operating weight of an aircraft?
OEW = DOEW + Catering Allowance + Flight attendents
Difference between airplane and aircraft?
Aircraft is a general term for anything that is capable of flight. This could include fixed-wing, helicopters, gliders, blimps, gyro copters, gyro planes, and balloons. Airplane typically refers to fixed-wing aircraft, but technically means anything with wings that is capable of flight.
What is the difference between air crafts and air planes?
The word aircraft - refers to any vehicle capable of flight - of which are hovercraft, gliders, planes and helicopters. The word airplane - relates only to fixed-wing aircraft.
What is an airmiss?
An airmiss is a narrow miss between two aircraft in flight.
What is difference between a KC-130 and a C-130?
A KC-130 has been produced for refueling other aircraft while in flight. The C-130 is a cargo plane.
How is life of aircraft structure counted?
It's counted in flying hours and flight cycles. The primary concern is flight cycles. A flight cycle is a take-off and landing. Airlines keep track of the Flight Time (hours) and Flight Cycles on the airframe and the same for the engines. Flight Cycles are primarily important for tracking aircraft metal fatigue and the time on the Landing Gear. The parts on the gear have a Safe Life Limit calculated by the manufacturer based upon fatigue tests and stress analysis. This limit represents the amount of cycles it can be flown before it will begin to develop fatigue cracks. Once the landing gear part reaches that cycle limit, it has to be removed and scrapped. The manufacturer analyzes the gear using various loads such as landing loads, taxiing loads, braking loads, turning loads and calculates a fatigue life for the part. They usually then divide this calculated fatigue life by 4 and this becomes the Safe Life Limit. Dividing by 4 is a safety factor to allow for variations of manufacture and environmental unknowns and statistical scatter in their data. The Airframe is also tested in a fatigue test for 2 or 3 times the time it will be in service. Many airframes have a 90,000 flight cycle limit. Some more. Helicopters will be less. This airframe life limit takes into account air pressure on the fuselage as it cycles from ground to high altitude. Also, a short test flight is counted as 1 flight cycle. As an example of the difference between hours and cycles, the Aloha Airlines Boeing 737 that lost part of its fuselage had only a little over 35,000 hours on the airframe, but the aircraft had almost 90,000 cycles on it.
What is average distance between aircraft carrier flight deck and water?
60 feet
What determines an aircraft's age?
An aircraft is officialy "born" on its rollout. From then, it is like a human birthday. Aircraft have flight logs in them that record the number of hours they've been flown. This is usually the marker used to determine the "age" of an aircraft. If the airframe has not been stressed because it sat around in a hanger, it has low hours and is nearly "good as new" from the point of view of its air worthiness. Also important for the larger aircraft is the number of takeoffs and landings. These determine the number of cycles of decompression and recompression with the ship's achievement of high altitude in transit, and then its return to the "normal" pressure on the ground. It is the number of flight hours on a craft, and the number of decompression-recompression cycles (on the larger airframes) that "age" an aircraft. Inspection, maintenance, and rebuilding cycles are all based on the hours on the airframe and engine(s).
Is flight deck an aircraft carrier?
There is a flight deck on an aircraft carrier but, it is not an aircraft carrier as there are many other ships that have flight decks on them. The amphibious assault ship is a good example.
What is the difference between an aircraft carrier and an assault ship?
An assault ship with a flight deck may resemble an aircraft carrier, but its purpose is to deliver marines and their equipment for amphibious attacks. Many navies use assault ships, but not all of them have a flight deck. An assault ship with its own flight facilities spares the aircraft carriers from the task of carrying marine air support. An assault ship cannot operate the high-performance combat aircraft that an aircraft carrier has, but it does not need them for the job it does. An assault ship does not fight enemy ships at sea. Its purpose is to land on an enemy shore and hold it until reinforcements arrive.
What is a flight engineer?
In aviation, a flight engineer is a member of the aircrew of an aircraft who is responsible for checking the aircraft before and after each flight, and for monitoring and operating aircraft systems during flight. The flight engineer usually has a background in aircraft maintenance and may reasonably be described as the "technical expert" member of the operating crew.
