transition altitude造句

• This setting is equivalent to the air pressure at mean sea level ( transition altitude ).
• Aircraft are not normally assigned to fly at the "'transition level'" as this would provide inadequate separation from traffic flying on QNH at the transition altitude.
• Once above the transition altitude, the altimeter is set to the international standard atmosphere ( ISA ) pressure at MSL which is 1013.25 hPa or 29.92 inHg.
• The "'transition altitude "'( TA ) is the altitude above sea level at which aircraft change from the use of local barometer derived altitudes to the use of flight levels.
• However, in some countries, such as Norway for example, the transition level is determined by adding a buffer of minimum 1, 000 ft ( depending on QNH ) to the transition altitude.
• On 25 November 2004 the Civil Aviation Authority of New Zealand raised New Zealand's transition altitude from 11, 000 feet to 13, 000 feet and changed the transition level from FL130 to FL150.
• In the United States and Canada, the transition altitude is 18, 000 ft . In Europe, the transition altitude varies and can be as low as 3, 000 ft . There are discussions to standardize the transition altitude within the Eurocontrol area.

• Therefore, aircraft may be flying at both transition level and transition altitude, and still be vertically separated by at least 1, 000 ft . In those areas the transition layer will be 1, 000-1, 500 ft thick, depending on QNH.
• Pressure altitude divided by 100 feet ( 30 m ) as the flight level, and is used above the transition altitude ( in the US, but may be as low as in other jurisdictions ); so when the altimeter reads 18, 000 ft on the standard pressure setting the aircraft is said to be at " Flight level 180 ".
• Calculation of Transition level :-suppose QNH is 1002 & Transition altitude of an aerodrome is 4000 ft . then transition level is equal to 4000 + ( 1013.2-1002 ) x 30 equals to 4342 ft which is nearer to flight level 45 then transition level will be 1000 ft above the transition altitude i . e Fl 55.
