pressure altitude การใช้

• The altitude transmitted is pressure altitude, and corrected for altimeter setting at the ATC facility.
• The aircraft pressure altitude and pitch angle were decreased while 160 knots computed airspeed remained maintained.
• True airspeed is equivalent airspeed that is corrected for pressure altitude and temperature ( which define density ).
• The scuba rule has to do with the bends as all flight has a pressure altitude above sea level.
• The tunnel was in the ground water at a pressure altitude of approximately 16 m to the bottom of the tunnel.
• It provides the aircraft's pressure altitude to the transponder, so that it may relay the information to the ATC facility.
• Mode C uses a spacing of 21 ?s, and requests the aircraft's pressure altitude, provided by the altitude encoder.
• Because primary radar generally gives bearing and range position information, but lacks altitude information, mode C and mode S transponders also report pressure altitude.
• The true airspeed can be calculated as a function of equivalent airspeed and local air density, ( or temperature and pressure altitude which determine density ).
• Aircraft Mode " C " transponders report the pressure altitude to air traffic control; corrections for atmospheric pressure variations are applied by the recipient of the data.
• :Note that for aircraft flying more than a certain minimum altitude above ground, the distinction between true altitude and the so-called pressure altitude is ignored.
• :Bondarenko's accident occurred on " " the tenth day of a 15-day endurance experiment in a low pressure altitude chamber . . ..
• Without the pressure altitude reporting, the air traffic controller has no display of accurate altitude information, and must rely on the altitude reported by the pilot via radio.
• In IGC-approved recorders, GNSS and pressure altitude data is continuously recorded during flight in the form of regular fixes stored in non-volatile memory inside the recorder.
• :: : The cabin pressure drops until a predetermined point ( 8, 000 feet IIRC ), then remains constant until coming back down through the same pressure altitude.
• However some performance charts will define the service ceiling as the pressure altitude at which the aircraft will have the capability of climbing at 50 ft / min with one propeller feathered.
• The pressure altitude system in an approved recorder has the same function as a barograph and must be calibrated to the ICAO ISA ( International Civil Aviation Organisation International Standard Atmosphere ).
• GNSS altitude data can be compared after flight with the pressure altitude data from the independent sensor in the recorder and this is a valuable check that both systems are working correctly.
• One study of 8 flights in Airbus A380 aircraft found a median cabin pressure altitude of, and 65 flights in Boeing 747-400 aircraft found a median cabin pressure altitude of.
