Tom was a fair man and trust me, dealing with some of the silly discussions I had engaged in over the years pushed the limit of his understanding. He gave all of us a forum that we could call home. For that alone, I salute him and wish him a happy journey into eternity.

Looking great as always guys - From an old friend

Sadde6 LAX eh ;p?

If you were cleared for an early descent (you stated you re-selected FL260 prior to T/D) why would you continue in VNAV without using DES NOW through the FMC or ALT INT feature? I don't understand how you were cleared "DOWN TO EGLL" yet set the MCP to FL260. Let's say you simply asked for descent clearance (normal OP) and reset the MCP (normal OP) and let he aircraft des in the profiled VNAV path. What's at FL260? Something you neglected to inform us on? You might get clearance to start your descent down but there are various restrictions (i.e. FL100 -sid restrictions, landing clearance etc)

Ok the MCP window will change to +20V2 under these conditions - You manually adjust the mcp spd knob and (one click will make it jump)You engage the A/P in cmd from TO/GA.

And you can say that real pilot tested the NGX, yes that's true. But maybe they didn't care about that detail, or maybe they thought it wasn't that important. That's the only assumption I see here and it's a pretty big one. I'm sorry but no one will take you seriously from hearsay - please provide concrete evidence when you make such claims. Evidence does not need opinions. I'm not saying you're right or wrong but if you are making a claim it is in your court to provide such..

I have a friend of my brother's wife, who happens to be my step mother's sister's niece who told me just the opposite. But hey what does she know considering she is in the know.

Are you talking about once you *reset the MCP speed window it should jump to V2+20 matching the magenta cursor? If so then yes it should do that - I'm not sure of anything has changed in that regards in the past few years but I doubt it. What I mean by jump is say you move the knob one click (lets say it's at 154) we move it 155 - it automatically goes to 174 on the MCP.

Why would the MCP SPD window change? The MCP window is manually set to V2. It is not set to V2+20 nor does it change to that.

but I don't understand why during normal take off it goes to v2+20 V2 is the min 1 eng out maneuvering speed. It's not the target SPD - that's v2+ 20+ depending although the magenta cursor shows according to - V2 if airspeed is less than V2;Existing speed, if airspeed is between V2 and V2+20; orV2+20 if airspeed is above V2 As the RA and V/S increase, the FD will command pitch to main-tain V2+20, allowing the pilot to transition to the FD. If you're manually flying you're manually flying spds. The MCP window spd is adjusted by you and since you're not engaed in CMD it does nothing but guiding for T/O v2+20. You take off maintaining V2+20 -accel height - retract flap @ speeds and engage modes of choice (Different SOPS will be different here so keep that in mind). Some verify lateral mode @ 500 RA, other can arm VNAV etc prior to T/O. But the point in all this is you fly the aircraft maintaining control via the F/D not a magenta bug or MCP window (although they are set for the F/D guidence).

Font issue perhaps?

Yep I noticed this too -

FCOM is clear as spin737 stated. That's the fact of what it commands. F/D is also has 'options' for wings level and HDG SEL on T/O.

I really think This is the point where you insert facts not opinion.

Gentlemen - how in the world do you think an airliner has the ability to hold a certain V/S without reference to flap up speeds? Would you really engage a pitch mode at 400 RA that has no V2 guidance or for maneuvering speeds? No you wouldn't. Could you engage it? I'm pretty sure you could but that does not remove the 'no you wouldn't' factor.
