Continental 737-300 Cockpit Question

Fri Nov 24, 2006 4:26 pm

In looking at some of the photos, it appears that this aircraft (in continental's configuration) does not seem to have wx radar, and also doesn't seem to have the radar that shows other aircraft in the vicinity. I do know that the 737-300 series aircraft built after 1990 have both, but these don't seem to.

The part you see there is just the blanking plate.

I think the question is why do these B733 have mechanical ADI and HSI? You can see the weather radar on the pedestal. Most B733 have EADI and EHSI same as B734, but these must be early B733 without it. Are there many B733 built like this? or was this special for CO?

Could it have been for an easier transition of 200 series crews or maintance reasons?

I've seen the steam engine gauges in 300's before but never the ADI's and HSI's.

The Weather Radar is on P9 centre.
The older B733 had the Older ADI & HSI.The later versions had the EADI & EHSI which were optional.
For A fleet of B732 & B733 it served the purpose of commonality.

There were some EFIS B737-300s in the fleet. They have since been retired.

Quoting Jamman (Reply 3):

Not a CO pilot but that is a likely explanation. The US FAA is not likely to approve pilots jumping back and forth between semi-glass and iron gauges. They might well allow them to fly both -200 (with JT-8D) and -300 (with CFM-56) but not the different style flight instrument. Something similar seems to be going on at Southwest where they use their full glass cockpit to simulate pictures of round gauges.

USAir ordered their -300s with the same instrumentation as their older -200 fleet, presumably for this reason.

BA for many years had dual qualified pilots on B732 and B734. The B734 have EADI and EHSI, but round engine gauges. BA and KLM both bought round gauges after the BM B734 crash at Castle Donnington which was attributed to misreading of the TV gauges.

In your pic with your post Atryman those are the round dials that CO has in all their -300's now, the EFIS -300's are all gone, and that is the only plane they have with round dials!

The weather radar and TCAS are combined in a in reply 1 just above the trottle levers, right of the speed brake and left of that flap handle.

IRC the CO -300 round dials have always been configured with the weather radar and TCAS in same spot.

Hope your enjoying home this weekend!!  Smile

I enjoyed it for one day. Now I am in Lake Tahoe. It was a nice flight up this morning (in a 737-300 as discussed above). Thanks for your comments

Ah hah! So we can rule out one airline that you flew for. Am I the only one who occasionally wonders?

Sorry for going off topic.

WN 733's and 755's are the same way. They have the traditional steam gauges. I have been told that this was to ease transition between the 732 and the 733. Example, I am currently working on N642WN, one of the last 733's delivered new to WN, in 1997, and it has the mechanical gauges.

CO's -300s (737-3TO) TCAS systems were installed after the A/C were delivered. The radar indicatior is used to show other A/C positions and the VSIs have red indicators for fly up or down incase a resolution advisory is required when another A/C comes within so many feet of you.
Is it broke...? Yeah I'll fix it.
