Wing fence. Close up of the wing fences of a Sukhoi Su-22. This plane was used by Former East German Air Force and retired after German unification. Wing fences, also known as boundary layer fences and potential fences are fixed aerodynamic devices attached to aircraft wings. Often seen on swept-wing aircraft, wing fences are flat plates fixed ...
Aircraft maintenance checks. Aircraft maintenance checks are periodic inspections that have to be done on all commercial and civil aircraft after a certain amount of time or usage. Military aircraft normally follow specific maintenance programmes which may, or may not, be similar to those of commercial and civil operators. [citation needed]
An airman services a jet blast deflector (JBD) before flight operations aboard an aircraft carrier. A jet blast deflector (JBD) or blast fence is a safety device that redirects the high energy exhaust from a jet engine to prevent damage and injury. The structure must be strong enough to withstand heat and high speed air streams as well as dust ...
Aviation obstruction lighting is used to enhance the visibility of structures or fixed obstacles which may conflict with the safe navigation of aircraft. Obstruction lighting is commonly installed on towers , buildings , and even fences located in areas where aircraft may be operating at low altitudes .
Multiservice tactical brevity code. March 2023 edition cover page of the Multi-Service Brevity Codes. Multiservice tactical brevity codes are codes used by various military forces. The codes' procedure words, a type of voice procedure, are designed to convey complex information with a few words.
A wingtip fence refers to the winglets including surfaces extending both above and below the wingtip, as described in Whitcomb's early research. [10] Both surfaces are shorter than or equivalent to a winglet possessing similar aerodynamic benefits. The Airbus A310-300 was the first airliner with wingtip fences in 1985. [22]
The effect is the same as a wing fence. [2] It can also be used on straight wings in a drooped leading edge arrangement. [citation needed] Many high-performance aircraft use the dogtooth design, which induces a vortex over the wing to control boundary layer spanwise extension, increasing lift and improving resistance to stall.
Preflight checklist. A Royal Australian Air Force pilot conducts a preflight inspection of an F-35A Lightning II at Nellis Air Force Base, Nevada, April 27, 2022. In aviation, a preflight checklist is a list of tasks that should be performed by pilots and aircrew prior to takeoff. Its purpose is to improve flight safety by ensuring that no ...
