Sirs, When flying a route with an A320 for example; if I wanted to overfly a waypoint I would press on the MCDU;http://www.bird.ch/nilsalegren/a340/cockpi...uttons/OVFY.giffor a specific waypoint.I was wondering how Boeings preform this as I don't think the Boeing FMC's have an "overfly" button like Airbus. Does an NG captain just fly it manually?Many Thanks.
