Above the TA, the aircraft altimeter pressure setting is changed to the standard pressure setting of 1013 hectopascals (equivalent to millibars) or 29.92 inches of mercury, with the aircraft altitude will be stated as a flight level instead of altitude. In the United States and Canada, the transition altitude is 18,000 ft (5,500 m). [5]
The highest altitude obtained by an electrically powered aircraft is 29.524 kilometres (96,863 ft) on August 14, 2001, by the NASA Helios, and is the highest altitude in horizontal flight by a winged aircraft. This is also the altitude record for propeller driven aircraft, FAI class U (Experimental / New Technologies), and FAI class U-1.d ...
In aviation, atmospheric sciences and broadcasting, a height above ground level (AGL [1] or HAGL) is a height measured with respect to the underlying ground surface.This is as opposed to height above mean sea level (AMSL or HAMSL), height above ellipsoid (HAE, as reported by a GPS receiver), or height above average terrain (AAT or HAAT, in broadcast engineering).
It is the setting that causes an altimeter to read the aircraft's flight level (FL). Flight levels are given in hundreds of feet (for example: FL100 = 10 000 ft). Atmospheric pressure changes over time and position. Thus, the flight level is not "straight", because it has a different altitude (elevation above the mean sea level).
Absolute altitude is the vertical distance of the aircraft above the terrain over which it is flying. [ 3 ] : ii It can be measured using a radar altimeter (or "absolute altimeter"). [ 3 ] Also referred to as "radar height" or feet/metres above ground level (AGL).
The service ceiling is the maximum altitude of an aircraft during normal operations. Specifically, it is the density altitude at which flying in a clean configuration , at the best rate of climb airspeed for that altitude and with all engines operating and producing maximum continuous power, will produce a given rate of climb.
The maximum altitude allowed is 400 feet above the ground and the maximum speed is 100 mph. ... such as requirements for drone operators to register their aircraft locally as well as with the FAA. ...
The cabin altitude of the Boeing 767 is typically about 7,000 ft (2,134 m) when cruising at 37,000 ft (11,278 m). [11] This is typical for older jet airliners. A design goal for many, but not all, newer aircraft is to provide a lower cabin altitude than older designs. This can be beneficial for passenger comfort. [12]
