Hi

I have noticed in some photo's that the classic 737 has 3 different types of cockpit layout.

I always thought that when the 737-300 was rolled out it came with an EFIS PFD & NAV Display but i have seen some completey analogue (737-200) type cockpits on the -300.

Does anybody know when:

1) The EFIS was rolled out as standard?

2) The digital engine indication system was rolled out as standard?

It probably depends a bit on the customer. If the operator also had some 737 Jurassics, they might have wanted to keep commonality backwards.

The EFIS was actually introduced on the 737-500, and was subsequently offered as a production option on 737-300's and 737-400's manufactured after the -500 was certified...

WN actually paid extra for Boeing to put a classic six pack cockpit in the -500's (for commonality with the rest of the fleet, which at the time was a mix of -300's and -200Adv's)

That must have been fun once they started buying -700s...

They just had Boeing program the EFIS displays in the -700's to emulate a six pack

I thought EFIS was an option since the first 733 days, but it became standard once the -500s were being produced?

I think WN had a lot of things dumbed down on the 733/5s until the NGs came... No Autobrakes, No VNAV, No A/T up to a point... can't remember what the things they went for...

Rapping flight attendants and a lack of pre-booked seats.

I was just looking at some WN 733 flight decks and they have only 1 FMC and no N1, SPEED, or VNAV

But they do have LVL CHANGE

So LVL Change just holds a speed via pitch attitude with a manually set power setting??

So NO AUTOTHRUST. That does surprise me.

I don't know if they still do it, but Boeing did a separate version (or mode) of the avionics software to make the displays show something rather more like the classic steam gauges. Just for Southwest and commonality with their older aircraft.

It's still around.

I think it was done primarily at Southwest's urging, but it's available for anyone who wants it.

I think Continental uses that "virtual steamgauge" mode too...

Continental does have that option.

Although this a/c does not.
Unusual to have a mix?

AND THIS ONE HAS A MIX!
Is it pilot selectable via a switch?
It is very unusual to see a split in EFIS style like this.

And here the same a/c pictured above now shows an entirely 'steam driven' type display.
There must be a selector switch somewhere?

Who else has it?

Ok I have realised that the 'mixed display' photos above were taken at an airshow so it's likely a one off for demonstration to potential customers.

My bad.
