A quick idea for you to try out.Method 1.1. Set the FMC up fully with all the Vspeeds etc.2. Set V2 speed in the MCP SPD Window.3. Arm Autothrottle.4. Switch FD On5. Enagage TOGA Mode - Little screw on top left hand side of MCP is hidden click spot for this.6. Passing 400ft Engage VNAV/LNAV - do not switch on the autopilot.What you have now is the MCP/FMC/Autopilot data being fed to the FD, while you handfly the airplane. 7. Passing 1500ft or accel height start to retract flaps as the FD pitches down slightly.8. Continue hand flying to TOC or whenever you feel like switching the autopilot on.Method 2.1. Set the FMC up fully with all the Vspeeds etc.2. Set V2 speed in the MCP SPD Window.3. Arm Autothrottle.4. Switch FD On5. Enagage TOGA Mode - Little screw on top left hand side of MCP is hidden click spot for this.6. Passing 400ft Engage LVL CHG/LNAV - do not switch on the autopilot.What you have now is the MCP/FMC/Autopilot data being fed to the FD, while you handfly the airplane. 7. Passing 1500ft or accel height increase speed in MCP SPD window to 250 Knots. Retract Flaps on schedule.8. Continue hand flying to TOC or whenever you feel like switching the autopilot on.It is unwise to use VS Mode in the climb. IN VNAV or LVL CHG Mode, the autopilot system will not allow speed to decay. It will alter pitch to maintain the target airspeed. In VS Mode the autopilot does not do this, and so speed can decay.

Thx for prompt reply, I truly glad that you answer . . .However after studying the 747 on real world, and looked into many

http://www.smartcockpit.com/b737/B737%20TO_BRIEFING.PDFhttp://www.smartcockpit.com/b737/B737%20CLIMB%20BRIEFING.PDFThese 2 documents are quite good. I think I know how to get you setup to use VS correctly.1. Do all the FMC stuff etc as before.2. Enter the V2 speed in the MCP SPD Window3. Arm Autothrottle4. Enagage TOGA Mode5. Keep this mode enagaged till acclel height.6. Enter VS of 500 in MCP VS Window7. Accel to 250 knots.8. increase VS to what ever you feel comfortable with, while monitoring airspeed. If speed starts to drop then decrease VS.9. Passing 10000ft Decrease VS and increase speed to 290 knots.10. Once at 290 knots increase VS and again watch for speed decay.This should work okay.

I will give a detailed responce.. A few minutes ;) [h4]Best Wishes,Randy J. Smithhttp://www.precisionmanuals.com/images/betaimg.jpg

I will say this, please post a screenshot of the complete panel when you are trying whatever you are trying to do. This aircraft is extremly complex and one can forget or not know the limitations (if any) for the particular mode. FYI, you never ever set more than V2 on the MCP for takeoff, there are no exceptions to this rule.... [h4]Best Wishes,Randy J. Smithhttp://www.precisionmanuals.com/images/betaimg.jpg

Thanks again guys it is marvelous how fast you answer.What you mean about no more than V2 on MCP? Well V2 is 146 in example and I set 156, as I actually see on those videos I mentioned before, but not sure if I am right. I mean if you accelerate (manually) to 250knots, which I thinks shouldn

Because this is modelled after the real aircraft. You do not need to set more than V2 because in TO mode the F/D is commanding a V2+20 pitch. Also, the white bug is commanding V2+15 (minimum safe speed). Once you move the MCP SPD (one click) the speed will change to V2+20 on the MCP SPD window by itself so it will be commanding MCP SPD. Once you engage an autopilot the same will happen. You might not always SEE what is touched on videos, but be assured we have real NG pilots fying this bird and some crazy realism nuts like myself who check all these little details ;) [h4]Best Wishes,Randy J.

Ok this post got my curiosity up and here's what I just did:Set the 700 on the runway, no FMC entries at all. I engaged the AT and FD, set 160 in the MCP speed window, set flaps 1 and pushed the throttles to takeoff power. Roated at about 135 knots and pitched to maintain 160 knots through 400ft. (I didn't even press TOGA) Engaged CMD and set VS to 1200 FPM and SPD to 160 - the plane had absolutely no trouble climbing like this and in fact had to reduce the engine thrust drastically to avoid going faster than 160 at that pitch. I'm not sure how you could possibly be stalling like this... you're positive the AT is engaged and controlling the engine thrust to maintain 160?Please know though that this is absolutely NOT a real world procedure and you will not see a real airline pilot taking off or climbing like this! VS is an unprotected vertical mode and if you let it, it WILL stall the airplane, unlike LVL CH or VNAV. That is not a good thing! The way MS forces you to takeoff in the default 737 is nowhere near the way it happens in real life. At the very least you should be climbing in LVL CH mode. The FMC preflight is a vital part of preparing this airplane for flight, EVEN if you don't intend to use VNAV and LNAV... very comprehensive manuals and tutorials are coming with SU2 and it would be to your advantage to learn the real world procedures for preflighting the aircraft and the proper takeoff steps...Ryan

Hi Guys,Just a quick one,When I take off with TOGA and all fmc preflight done etc and I am climbing up. Passing 1000 speeding up retracting flaps and then hand over control to the AP My VS is between 3000 to 6000 nearly everytime when using VNAV as the pitch control. (vnav seems to be very good at using high rates for either climb or dest)This cant be right can it? I think my passengers will be a bit uncomftorble at this rate of climb.What rate of climb is expected or recommended - well on average anyway?What could I be doing wrong for this to happen?Thanks for any replysMark

These climb rates are in the ball park of what the -600 can achieve. It is overpowered so to avoid excessive climbrates derate the engines before take off. As I understand it derating is always done unless you have a short runway, wet or contaminated runways or something similar.I seldom take off at nominal rates even with full load. As for pax comfort. It doesn't really matter what your rate of climbs are. It's more related to pitch angles and g-forces applied.Hope it helps,TGIF, :-beerchug

Hi Mats,Thanks for the info. I will use the derated settings later and see the difference :)Out of curiosity do the maximum ratings get used when the runway is flooded or its raining (heavily) or a mixture? (cause I tend to fly in rainy UK)Thanks for the quick replyMark.(ps the pitch was above 23 degrees so my pax were definitly a bit uncomfortable the last few times)

I do not think FS models a contaminated runway if at all. The AFDS does not take PAX comfort into account, that's the pilot's job. The 737 NG is well known for it's aggressive pitching behavior. Here's a real world cheat, either use CWS or V/S to begin your climb smoothly, once established in the CLB engage VNAV.......[h4]Best Wishes,Randy J.
