The salient point in his screen shot, aside from whether the FMC perf is properly set up, is that the autothrottles are turned off. Thus, there is no...

This explanation deals with speed intervention in a descent, not once the VNAV shifts into approach logic. At that point, even with the speed intervention...

[Stearmandriver]

Just curious where this happened? Kind of seems we're all in agreement here......

[Stearmandriver]

Well, the speed you've set in the window is being commanded, in the sense that the speed bug on your PFD is indeed showing 210 knots. It's weird that...

I do. Golf in all 50 states... that's pretty good! I'm not a golfer myself, but I think managing to do anything in all 50 states is tough.

Alaska runs -800s and -900ERs from ANC, SEA, PDX, SMF, OAK, SFO, SJC, LAX and SAN to LIH, HNL, OGG and KOA. Roughly 20% of our 737 flying is ETOPS to/from...

[Stearmandriver]

Well, I don't know that it's any easier? You've already bugged a wind correction in the box, and if a modification is desired on final it's easy enough...

[Stearmandriver]

Oh I agree the PMDG implementation is good... I'm still on the NGX and continually impressed by what I can make it do. I do see it get glitchy sometimes...

[Stearmandriver]

I actually really did not know this, thanks! That's why I like the discussions here... I learn a lot about how other airlines fly the same plane. Our...

1. Why were you using speed intervention? The PMDG box and autoflight struggles with complex procedures anyway; probably best not to compound the issue...

[Stearmandriver]

Auto-arming of LNAV for a go around notwithstanding, selecting a pitch mode should not affect the roll mode. Procedure at my airline is to call for LVL...

[Stearmandriver]

One other tool here is to calculate a "latest touchdown point". You do this by calculating landing data first, then your LTP = Available Landing...

[Stearmandriver]

I understand what the flight guidance is doing. I'm saying that the indication itself is wrong. You're not "waiting to intercept" the final...

[Stearmandriver]

?? The table is entirely in context and relevant to this discussion. It's a breakdown of every possible combination of roll and pitch mode you can fly...

[Stearmandriver]

It's the second screenshot that I believe is incorrect. In the first, you've captured the final approach course, your roll mode is FAC, and your pitch...

[Stearmandriver]

I'm sure this table is taken straight from Boeing documentation. This website isn't just someone's blog, it's a clearinghouse of accurate information...

[Stearmandriver]

Ok, I found guidance on a popular 737 study site that includes a table of possible FMA mode annunciations during an IAN approach. Note that there is no...

[Stearmandriver]

I'm not questioning whether the plane gets to the runway with these mixmatched flight guidance modes, but rather I'm doubting that the real plane would...

[Stearmandriver]

On any non-precision approach, you'll be visual with the autopilot disconnected prior to the MAP, or you'll miss.

I don't think your screenshot...

[Stearmandriver]

I must be missing something. If the IAN roll mode is annunciated white and not green, that means it's armed and not active. So how is the IAN mode working...
