The absolute ceiling is the highest altitude at which an aircraft can sustain level flight. Due to the thin air at higher altitudes, a much higher true airspeed (TAS) is required to generate sufficient lift on the wings.
V x increases with altitude and V Y decreases with altitude until they converge at the airplane's absolute ceiling, the altitude above which the airplane cannot climb in steady flight. The Cessna 172 is a four-seat aircraft. At maximum weight it has a V Y of 75 kn (139 km/h) indicated airspeed [4] providing a rate of climb of 721 ft/min (3.66 m/s).
This is important for clearing an obstacle, and therefore is the speed a pilot uses when executing a "short field" takeoff. V X increases with altitude, and V Y decreases with altitude until they converge at the airplane's absolute ceiling. Best angle of climb (BAOC) airspeed for an airplane is the speed at which the maximum excess thrust is ...
Service ceiling: 14,300 ft (4,400 m) Absolute ceiling: 16,400 ft (5,000 m) Rate of climb: 550 ft/min (2.8 m/s) at sea level; 585 ft/min (2.97 m/s) at 5,000 ft (1,500 ...
Absolute ceiling: 21,000 ft (6,400 m) Rate of climb: 1,250 ft/min (6.4 m/s) Take-off run to 50 ft (15 m): 600 ft (180 m) Landing run from 50 ft (15 m): 600 ft ...
Tragically, White could've bid more — his absolute ceiling was $45,000 — but he didn't want to go all in all at once. And then he ran out of time after the anonymous $40,500 bidder swooped in ...
Lawyers who secured a $1.1 billion settlement in the deadly collapse last year of a beachfront Florida condominium building were awarded more than $70 million in fees Monday by a judge. The total ...
On June 21, 1972, Jean Boulet of France piloted an Aérospatiale SA 315B Lama helicopter to an absolute altitude record of 12.440 kilometres (40,814 ft). [66] At that extreme altitude, the engine flamed out and Boulet had to land the helicopter by breaking another record: the longest successful autorotation in history. [ 67 ]
