When I first initialize the FMC, I pluf in the dep[arting and arriving airport (cyvr/cyyc) then the rest of the info and click next page and it always gives me a "not allowed" message. Any ideas? I worked the very first time I tried it a couple days ago. Thx

Hi,if the engines are already started, you can't access INIT B page, this is correctly replicated. So you must complete the entries for the INIT B page before engine start.Mike

Hey Mike thanks very much sir. I did not know that. THZ
