Southwest Old Cockpits On 737-3/500

Mon Jan 17, 2005 8:16 pm

Hi all, I have noticed in some photos of Southwest's 737-300's and 737-500 there are no EFIS screens. The flight deck resembles that of a 737-200. I thought that all 737-3/4/500 had an electronic ADI and HSI, I know that the early ones had analogue engine displays, but these still had an electronic ADI and HSI.

My question is, why have southwest got 737-300's and 500's with a completely old style flight deck.

Was it a request for commonality with its 737-200's to save costs?

Thoughts would be appreciated

Here is another example but it's a 737-500

Maybe they just modded the aircraft to be 300-500 series instead of new off the line ones.

Or

perhaps they specifically requested antiquated cockpits to reduce the cost of the new stuff there by saving money and providing cheap transportation.

I believe so. I know on SW's 73NGs Southwest specifically requested the EFIS screens be formatted to have an analog style to simplify commonality. I believe they're the only airline to request the EFIS screens be formatted in such a way.

I believe analog style instruments (ADI, HSI) were standard equipment. EFIS was optional. Southwest was not the only operator of analog 733 & 735s. I'm sure you could probably find 734 cockpits with full analog instrumentation.

As for the NG cockpits, I agree with 777STL that it was Southwest who prompted Boeing to offer the two display styles. However, SWA was not the only customer for the EFIS style NG cockpits (not a comprehensive list):

Heh, I didn't know that. Thanks for clearing that up.
