Is PRE-FLT COMPLETE supposed to show before you've specified flap configuration and v-speeds on the takeoff page? I notice that the PRE-FLT COMPLETE indicator is displayed as soon as I enter the TAKEOFF REF page - even though I haven't entered any data for flap or v-speeds. In the '67, this data must first be input before the FMC gives you the green light. Not so in the NG?Jason Barlow

Hi Jason,My Boeing manual (for the 3/4/5) has this to say:"PRE-FLT STATUSSelectively displayed to allow line selection of the appropriate preflight pages whenever the required entries on those pages are incomplete. (...) After completion of all required items "PRE-FLIGHT COMPLETE" appears."The pages referred to are POS INIT, PERF INIT, ROUTE, DEPARTURE.My Lufthansa manual, also for the 3/4/5, says this:"Following completion of required entries on the POS INIT, RTE and PERF INIT pages, all status prompts blank and PRE-FLT STATUS is replaced by PRE-FLT COMPLETE"So it seems that this behaviour in the sim is correct.Leo Bakker
