The effect of altitude on the power required of a propeller-driven aircraft with same weight. Power required is inversely proportional to the endurance for a given fuel load. In aviation, endurance is the maximum length of time that an aircraft can spend in cruising flight. In other words, it is the amount of time an aircraft can stay in the ...
Four-engine carrier-based Fleet shadower/follower – low-speed, high-endurance, ship-tracking aircraft – requirement later rendered obsolete due to introduction of radar: Airspeed AS.39, General Aircraft GAL.38: S.24/37 OR.53 Naval torpedo/dive-bomber, reconnaissance – Supermarine entry featured variable-incidence wing
For most unpowered aircraft, the maximum flight time is variable, limited by available daylight hours, aircraft design (performance), weather conditions, aircraft potential energy, and pilot endurance. Therefore, the range equation can only be calculated exactly for powered aircraft. It will be derived for both propeller and jet aircraft.
The Navy determined that the elimination of the ABNCP and "Looking Glass" requirements reduces the crew size and endurance requirements, allowing for a much smaller aircraft. [7] Additionally, using a C-130-based platform ensures training and supply chain commonality with other US military C-130 programs. [7]
Aircraft manufacturers will publish performance data in an aircraft flight manual, concerning the behaviour of the aircraft under various circumstances, such as different speeds, weights, and air temperatures, pressures, & densities. [5] [6] Performance data is information pertaining to takeoff, climb, range, endurance, descent, and landing. [1]
Combat endurance is the time that a military system or unit can remain in combat before having to withdraw due to depleted resources. [1] The definition is not precise; for example the combat endurance of an aircraft, without qualification, is usually the time the aircraft can remain at an altitude suitable for combat, but in a particular theatre of operations it is the time it can remain in ...
The flight endurance record is the longest amount of time an aircraft of a particular category spent in flight without landing. It can be a solo event, or multiple people can take turns piloting the aircraft, as long as all pilots remain in the aircraft.
Endurance requirements of over 12 hours were especially hard to meet, as there are limitations of an aircraft's wingspan for holding fuel on the confined space of an aircraft carrier; the UCLASS had to maintain two 600 nmi (1,100 km; 690 mi) orbits around the ship, or one orbit at a range of 1,200 nmi (2,200 km; 1,400 mi), with the ability to ...
