A/C "Request the option"
TWR "Cleared for the option"
is occasionally heard before a touch and go at Biggin Hill - it is used by instructors to surreptitiously ask for permission to do an EFATO drill after the T&G.
Non-standard, however it is technically a local agreeement.
As for QFE, is there another country that still uses it? Do any airline still use it? (I know that BA/BEA/BOAC and some US airlines used to, but it's been long since phased out).
