POSKY FDE and aircraft takeoff performance question

Featured Replies

Issue with POSKY CRJs and B737NGs mainly. Need some help to sort this out. When I use the usually prescribed 5deg flaps and TOGA and then 10deg climb out the plane rockets past 250kias and keeps going until I have to retard the throttles significantly. Surely this is not normal behavior of these aircraft in real life? This is not the case with say the PA Airbus A320. What can be done to make it more realistic? Am I not setting the right flaps etc.? It certainly takes off nicely but more like an F15 than a pax a/c. Also with the POSKY CRJ-700 the bank angle for an autopilot coordinated turn is ridiculously high, pax pinned to the windows Shocked.gif What can be adjusted for this to be corrected? Thanks Shez

I haven't used those 2 but with the PMDG 737 and LevelD 767, normal rotation is to 15° initially and once airborne and accelerating, to increase to about 20°. This was also the case in the real B737-200 and B767 where we normally would not go above 20° for comfort , ( and the F/As would struggle too much with the trolleys above that body angle.) If the models are capable, you could use reduced T/O power by using the assumed temperature method as on the LevelD or fixed Derates, if available. Failing that, increase TOW up to the max. Is there no bank angle control for the Flight Director or autopilot on the Mode Control Panel as there is on the LevelD? While we're here, Thanks a lot for all your sceneries which I have been using for some time. Colin B

Thanks Colin, Maybe I will try a higher climb out rate as you suggested to keep speeds down. I have tried to boost TOW but I usually try and keep a realistic balanced weight. Shez

I know the Posky 737 comes with some checklists, in which they state the max N1 for takeoff and climb. When I try to follow these values, I find my aircraft does not overspeed so easily. At sea level and 15ªC (59ºF), TO N1 should be 88.3%, not the 104% that you'll get if you firewall the throttle levers. Hope this helps. Best regards from Colombia,Luis Miguel

OK let me check out where the checklists are. Shez
