October 22, 201114 yr Ok say i have V2 speed in FMC to 134, do you then set the 134 V2 speed in the MCP or do you add +20 to it? so insted 134 you add 154 into the MCP ?
October 22, 201114 yr You're supposed to set V2. The FD will automatically show a pitch that will lead to a V2+20 speed despite the speed setting in the MCP. It's also entioned in the tutorial prepared by Ryan (I think). George Golas ---------------------- I hate gravity!
October 22, 201114 yr Fine, set it as V2+20, that is the option we used. We're just trying to educate people here, either option is correct is basically what we're saying, they'll just need a bit more research to find out what procedure the company they are flying for uses..... Rónán O Cadhain.

We're just trying to educate people here, either option is correct is basically what we're saying, they'll just need a bit more research to find out what procedure the company they are flying for uses.....I'm always finding there are many options for the 737. The basic guidance is for V2 to be set in the MCP. I suppose Boeing could come up with other options. However, the setup for the sim is to set V2 in the MCP, no? Matt Cee
October 23, 201114 yr Yes. I always set V2 in the MCP and then arm VNAV either before takeoff or after crossing through 400' ft AGL. I arm the A/T before lining up, engage TOGA after N1 stabilizes at about 40%, and I let VNAV do the rest in terms of speeds. I never "bug up" nor have I ever gotten the flashing "A" by not bugging up. Once you reach your acceleration height, pitch the nose down (following FD cue) to begin gaining speed and as soon as speed is increasing, retract flaps one notch. Then follow the FD commands to continue acceleration and retract flaps as you reach the flap speeds. VNAV should automatically "bug up" for you...at least that's how I've always done it.

October 23, 201114 yr No. just setting V2 is correct! Try to find some real 737NG flight video on YouTube and get convinced. / Leffe Leif A Mikkelsen **********************
October 23, 201114 yr If you set the MCP V2+20, the F/D is going to give you an initial climb of V2+40 - not so good in an engine failure. Matt Cee

October 23, 201114 yr Now with regards to this, I'm not sure if that's a software update that is present in the NG, so an NG pilot will have to inform us there, but basically, it wasn't there in the classic series. If it does do that though, just fly at V2+20 anyway, you're a pilot, not a button monkey and the majority of the time you won't have an engine failure, so it's safer to have V2+20 bugged for your departure if you haven't got VNAV armed.....I'm current on both Classics and NG, and the guidance is the same: if an engine failure occurs during takeoff, the pitch command target speedis:- V2, if airspeed is below V2- existing speed, if airspeed is between V2 and V2 + 20- V2 + 20, if airspeed is above V2 + 20 Sorry, but to me it doesn't sound like a matter of preference. To guarantee the performance requirements, you need to fly at V2 to V2+20 and to get that guidance, you need to bug V2. I've flown for two 737 operators and jump seated on several others and they all did it the same: Bug V2. Could you dust off your old manuals and take a peek? I'd like to see what the guidance would say if it was otherwise. Matt Cee

Don't have my manuals anymore, but I'll get my hands on some and get back to you on that one, I'm 100% certain though that we used V2+20 on our MCP when we were operating them... Out of curiosity, which side of the pond are you operating on? [Not that it should make much of a difference, just curious] Rónán O Cadhain.

Maybe the next time I'm laid off, I'll try to find a European operator. Matt Cee
October 23, 201114 yr Oh bugger, alright, I've just gotten off the phone with another pilot at EIN who also used fly the classics with me [not exactly the kind of telephone call you'd be expecting on a Sunday afternoon, but these are the lengths I go to for yee] and I've been set straight, so, to swallow my pride, Set V2 in MCP and then it will automatically increase to MCP+20 after takeoff, sorry about that, I was dead sure, although 16 years away from an aircraft can leave things a little blurry, sorry for any misguidance here, totally my fault....So correctly, the MCP window will show V2 but the speed bug will display V2+20... Oh darnation.... Rónán O Cadhain.
