How do you measure the lifespan of an airplane?
The lifespan of aircraft is determined by the manufacturer. The age is calculated based on pressurization cycles. As a rule of thumb, each cycle involves “takeoff/landing.” Fuselage and wings suffer stress from pressurization, including on “short hauls.”
Why are plane wings bent?
Airplanes’ wings are curved on top and flatter on the bottom. That shape makes air flow over the top faster than under the bottom. As a result, less air pressure is on top of the wing. This lower pressure makes the wing, and the airplane it’s attached to, move up.
How do they keep runways ice free?
Airports work with the FAA, the ultimate controller of all the aircraft, to temporarily close runways so they can be plowed. At Kennedy, Junge says, it takes two liquid dispensing trucks with 75-foot-wide spray booms to cover each runway in liquid product ahead of a storm.
How is the lifespan of an airplane determined?
“Aircraft lifespan is established by the manufacturer,” explains the Federal Aviation Administration’s John Petrakis, “and is usually based on takeoff and landing cycles. The fuselage is most susceptible to fatigue, but the wings are too, especially on short hauls where an aircraft goes through pressurization cycles every day.”
What’s the life expectancy of an F-16 Fighting Falcon?
This upgrade program, scheduled in 2011 to complete in FY14, replaces known life-limited structural components and maintains the original design airframe life of 8,000 flight hours. Structural upgrades in the F-16 SLEP include rework and replacement to extend airframe structural service life by 25% (6-8 years).
How long is the service life of an F-16?
The F-16 Service Life Extension Program (SLEP) extends the F-16A/B service life to 8,000 hours at a cost of $703K per aircraft in Fiscal Year 98. The F-16 Pre-Block 40 aircraft were developing structural cracks that must be repaired.
What makes a fighter aircraft a good fighter?
The success or failure of a combatant’s efforts to gain air superiority hinges on several factors including the skill of its pilots, the tactical soundness of its doctrine for deploying its fighters, and the numbers and performance of those fighters.
What are the features of a fighter aircraft?
A fighter aircraft, often referred to simply as a fighter, is a military fixed-wing aircraft designed primarily for air-to-air combat against other aircraft. The key performance features of a fighter include not only its firepower but also its high speed and maneuverability relative to the target aircraft.

What was the life expectancy of a pilot in World War 1?
Amidst all this chaos, pilots were dropping like flies. Early in the war, a pilots life expectancy could be several weeks, but by the Spring of 1917 (bloody April) A pilots life expectancy was only a couple of hours.
