Thanks for the replies. If I was cleared lower would I have to delete the FL21B in the fms or would it do it itself, presuming I put lower in the Mcp.
Say if there was an ‘at’ FL but on a arrival which included a descent would I leave it as a FL or still enter a B after it ?
Any tips would be good too. Yes the 800. I thought the max was the 8200!
Thanks
