In this video we talk in detail about the difference between QFE and QNH. We also will look into flight levels. #Microlight #Aviation #Popham

Can you please tell me clearly what is the concept behind different aerodrome have different QNH I am still confused

Q codes actually have no meaning at all - i.e. it is not an acronym.The mnemonics you use here are actually colloquial. QFE is just QFE and the "F" and the "E" do do stand for Field or Elevation respectively but it may be useful to think that they do for the sake of memorising them.

Qnh is atmospheric pressure at mean sea level then how it is different at different aerodomes
@YouHaveControl3 жыл бұрын
Either the aerodromes are very far apart. But when flying into an airfield QFE is usually used.

@@YouHaveControl Just expanding on this a bit - The actual air pressure at sea level can always change (vary from 1013.25). However, by having the protocol to set all our instruments to think it is 1013.25 (mean value), different aircraft within a given volume of air (say a 5 mile sphere in proximity) will always interpret/display the altitude reading the same. In this way separation between aircraft can be maintained - In the air above 3500ft you only really care about aircraft*, so you don't really care if 4000ft is precisely 4000ft (you only care that all other aircraft in the area 'agree' where they 'think' 4000 feet is - in reality it may be 4300ft for example, but to all aircraft with 1013.25 set it looks 4000ft). When landing the height of the ground (QFE) takes more precedence, especially when you can't see it in IFR so a local air pressure will be supplied by the airport to the pilots. This way you can ensure the ground is 0ft. (on cool days the QFE of my airstrip is 1002 for example, on roasting days it may be 1025, so it's always important to check). If you think you are at 200ft and the ground suddenly appears you have problems! *Unless you live in a mountainous area! P.S. Also great channel.

Do you fly in circuits at 1000 ft qnh?
@YouHaveControl3 жыл бұрын
Usually we fly in the circuit on QFE. The circuit height depends on the airfield.
