cmbaviator Posted May 3, 2016 Report Share Posted May 3, 2016 Hi guys there is something I don't understand, probably because i'm currently more used to the NG : after liftoff, and just above 400fts, i engage LNAV and VNAV but as soon as i engage VNAV, the thrust goes to reduced take off mode to Reduced climb, should reduced climb mode begin at 1500 fts ?? Also I think that the planes wants to accelerates to 250kts before 3000 fts (need confirmation). in the CDU, it is set at 1500/3000. Quote Link to comment Share on other sites More sharing options...
Val77 Posted May 9, 2016 Report Share Posted May 9, 2016 (edited) Hi If I'm not mistaken, engaging VNAV before flaps up is not a normal operation on classic. Use LVL CHG as usual. Not CDU like NG : There is only THR REDUCTION in Takeoff REF 2. There are many Noise Abatement Takeoff Procedure. PROC A is used in many airport in Europe and ur country : France. http://www.b737mrg.net/downloads/b737mrg_noise.pdfFrom runway to 1500 feet AGL : - take-off power - take-off flaps - climb at V2 + 10 to 20 knots (or as limited by body angle) At 1500 feet AGL : - reduce to climb thrust - climb at V2 + 10 to 20 knots (or as limited by body angle) At 3000 feet AGL : - accelerate to Flaps Up speed - retract flaps/slats on schedule - accelerate smoothly to en-route climb speed That's what I use often, as in Nice departure a+ Edited May 10, 2016 by Val77 2 Quote Link to comment Share on other sites More sharing options...
stefans85 Posted May 23, 2016 Report Share Posted May 23, 2016 It's 800 AGL not 1500. Quote Link to comment Share on other sites More sharing options...

Eddie Posted May 24, 2016 Report Share Posted May 24, 2016 Normal Thrust reduction altitude is 1500 fts AGL unless you have to perform a NDP He was referring to the thrust reduction altitude on an NADP, which is indeed 800' on both NADP1 and 2. 1 Quote Link to comment Share on other sites More sharing options...
