The maximum range condition is obtained at maximum lift/drag ratio (L/DMAX) The maximal total range is the maximum distance an aircraft can fly between takeoff and landing. Powered aircraft range is limited by the aviation fuel energy storage capacity (chemical or electrical) considering both weight and volume limits. [1]
The rule affected only those aircraft operating under IFR when in level flight above 3,000 ft above mean sea level, or above the appropriate transition altitude, whichever is the higher, and when below FL195 (19,500 ft above the 1013.2 hPa datum in the UK, or with the altimeter set according to the system published by the competent authority in ...
When the weight or center of gravity of an aircraft is outside the acceptable range, the aircraft may not be able to sustain flight, or it may be impossible to maintain the aircraft in level flight in some or all circumstances, in some events resulting in load shifting. Placing the CG or weight of an aircraft outside the allowed range can lead ...
For jet aircraft, "long-range cruise" speed (LRC) is defined as the speed which gives 99% of the maximum range, for a given weight. This results in a 3–5% increase in speed. [8] It is also a more stable speed than maximum range speed, so gives less autothrottle movement. [9]
A tactical air navigation system, commonly referred to by the acronym TACAN, is a navigation system initially designed for naval aircraft to acquire moving landing platforms (i.e., ships) and later expanded for use by other military aircraft. It provides the user with bearing and distance (slant-range or hypotenuse) to a ground or ship-borne ...
At a glance, the pilot can determine a recommended speed (V speeds) or if speed adjustments are needed. Single and multi-engine aircraft have common markings. For instance, the green arc indicates the normal operating range of the aircraft, from V S1 to V NO. The white arc indicates the flap operating range, V SO to V FE, used for approaches ...
Both aircraft plunged into the icy Potomac River shortly before 9 p.m. Wednesday and all 64 passengers on the American Airlines regional jet, along with three soldiers on the Black Hawk helicopter ...
Meanwhile, the first time that ETOPS-330 approval was given to a four-engine aircraft was in February 2015, to the Boeing 747-8 Intercontinental. [15] It is the only ETOPS-compliant aircraft allowed to run non-stop overflights over Antarctica with proper alternates, alongside the Airbus A340 and A380. [citation needed]
