Perfect Explanation. Thank you so much.

I noticed on the charts for 'St.Martan' airport that the transition level and altitude are different! ... FL50 level and FL65 Altitude ...

spot on.

Thanks for making it easy...best..

May I ask, when we are in cruise and ATC authorized us to descend BELOW the transition altitude, providing also the QNH: When we do the change in the altimeter setting? Right away when we start the descend; or when we are about to cross the transition level? (transition layer) Thank you!

Thank you!

That's great, thank you!

you are hero :) thank you !

thank you!!! it is perfect :D

Thank you, easy.

Thats great thanks for the video.. as I know between TA and TL we are not allowed to cruise either we climb or descend. I'm just wondering why? What happens between those two ?

perfect!!

Love

genius !!!

This is totaly wrong! Level from the name is when the Airplane fly at FL180 so that means here we should change to standard QNE 1013 mb!
