Am I remembering that incorrectly? Or did the CRT's age out and were replaced with the steam gauges as shown beside the EFIS/MAP combo CRT. Is there more unseen-in-the-photograph EFIS with engine/synoptic data on CRT's?
That's an EFIS/MAP airplane. A 757-200 RR. EFIS/MAP is the original cockpit instrumentation. Most advanced design on the market when it was introduced about 35 years ago... I took a picture of just the flight instruments.
Here's an Internet shot of the whole thing:
The center stack of EFIS displays is the EICAS (Engine Instrument and Crew Alert System). It shows engine performance on the upper CRT, and either additional engine or status information on the lower. Actually, all six displays are identical CRT units, driven by a display module (3 of them, with backups and switching) for each individual position. You can interchange CRTs. Helps with spare parts inventory.
