Altimeter Flashcards
A serviceable altimeter indicates
The elevation of the point selected plus the height of the altimeter above a point
Altimeter accuracy below 30,000ft
+-20m or 60ft up to 30,000ft
Altimeter accuracy past 30,000ft
+-25m or 80ft
When to you change from QNH to FL
At the transition altitude
When do you change from FL to QNH
At the transition level
QNH is rounded to the nearest
Rounded down to the nearest whole number for more terrain clearance
When is QNH given in the take off and climb phase
Setting made available to ac in taxi clearances prior to take off
When is the QNH given in Approach and landing
Given in approach clearances and clearances to enter the traffic circuit.
Who assigns the transition level
ATS unit
Highest two closely space aerodromes common transition altitude should be established which should be the
Highest that would be required if aerodromes were considered separate
Where is the transition altitude published?
In the AIP and on appropriate charts
Where is the transition level and the transition altitude
Transition level - HEAR - ATC + ATIS
Transition Altitude - READ - AIP + Appropriate charts
Consecutive flight levels shall be separated by pressure intervals corresponding to at least….
500ft in standard atmosphere
What is the transition altitude rounded up too
The nearest 1000ft (300m)
