Altitude reporting LGW
CLimbing on a Clacton 8Mike departure, I chcked in with 120,52(first dep. freq.) and told the controller my callsign and dep. route. The Controller reads back that I was supposed to say "LEVEL PASSING" and "CLEARED LEVEL" on initial contact.. .On the way to destination I spend some time with Jeppesen textbook, that use to have good anwsers to many questions, but found nothing about this "altitude reporting rule".. .Did i miss some basic knowledge, or is it hidden info. in some UK AIP ?
