HI BRYAN,CAN YOU EXPLAIN THAT WENT I SUPPOSE TO USE " ICAO A AND ICAO B ", AND SOMETIME WHEN I TRY TO USE ICAO B TO TRY OUT WHAT IS THAT FOR, I FIND THAT AFTER I TAKE OFF I CAN'T GET MY FIRST OFFICE TO DO HIS AFTER TAKE OFF CHECK LIST NOR TO RETRACT TAKE OFF FLAP TO FLAP 1. HOPE U CAN SOLVE MINE PROBLEM, THANKS SO MUCH.KENALI

Hello Kenali,Caps off please. That's hard to read :)ICAO A and B are just different takeoff profiles. They are described in Bulfer's charts that are included along with the rest of the manuals.The Departure Briefing needs to be done properly as it conditions the rest of the simulation; make a mistake and you can experience the problem you ran into.For the Dep Brief, make sure you hit these buttons:Flaps: 5ICAB: BSelect "V" for VNAV for the Automation Mode (AM).That's the easiest profile and most commonly used one. It will work everytime. If you forget to hit one of the above, things won't work properly.Hope that helps,Bryan
