Elevator (aeronautics) Elevators are flight control surfaces, usually at the rear of an aircraft, which control the aircraft's pitch, and therefore the angle of attack and the lift of the wing. The elevators are usually hinged to the tailplane or horizontal stabilizer. They may be the only pitch control surface present, and are sometimes ...
A functional flow block diagram (FFBD) is a multi-tier, time-sequenced, step-by-step flow diagram of a system 's functional flow. [2] The term "functional" in this context is different from its use in functional programming or in mathematics, where pairing "functional" with "flow" would be ambiguous. Here, "functional flow" pertains to the ...
Elevons or tailerons are aircraft control surfaces that combine the functions of the elevator (used for pitch control) and the aileron (used for roll control), hence the name. They are frequently used on tailless aircraft such as flying wings. An elevon that is not part of the main wing, but instead is a separate tail surface, is a stabilator ...
A destination dispatch elevator, here using a Compass system from Otis. Destination dispatch is an optimization technique used for multi- elevator installations, in which groups of passengers heading to the same destinations use the same elevators, thereby reducing waiting and travel times. This contrasts with the traditional approach, in which ...
Climbing elevator. A climbing elevator is a self-ascending elevator with its own propulsion. The propulsion can be done by an electric or a combustion engine. Climbing elevators are used in guyed masts or towers, in order to make easy access to parts of these constructions, such as flight safety lamps for maintenance.
Extra elevators have been constructed, which make up as many as five per every block. Lift Upgrading Programme (LUP) ( Chinese: 电梯翻新计划, Malay: Program Peningkatan Lif [1]) is a Singapore Housing and Development Board (HDB) project which upgrades and improves the facilities of the lifts at HDB flats. This project is for housing ...
An inclined elevator is a form of cable railway. Users with mobility and disability challenges often use an incline platform lift to climb staircases in their home with their mobility scooter or motorized wheelchair. Outdoor inclined elevators are used to access steep hillside property where stairs are not a preferred option for conveying ...
