Altitude Flashcards
What are the two common units for pressure?
Millibars(Mb)
Hectopascals(hPa)
What is the standard pressure at sea level?
1013hPa
What is the temperature of the international standard atmosphere?
15 degrees Celsius at sea level
When the temperature is less than the ISA, what will the effect be on the altimeter reading?
The altimeter will read higher than the actual altitude of the aircraft
What is QFE?
Field elevation(NYM is 700ft AMSl) setting altimeter to QFE would mean that it would read 0 at NYM
What is QNH
The air pressure at mean sea level
What is the definition of altitude
Vertical distance from SEA LEVEL
Why may flight levels cause problems.
On days of low pressure or high pressure, FL60 will be found at an altitude that is not 6000ft.
What should you say is the are asked to read what level you are?
-Whatever you can see on your altimeter
-Followed by ‘QNH’, ‘QFE’, ‘FLIGHT LEVEL’
On low pressure days in the UK, FL60 would be located where?
Lower than 6000ft
How high does an ATZ extend
2000ft above the airfield
