Just some points on the equipment fitted to CRJs.
From around 1996 all CRJ-100/200s have been fitted with -B engines but it is possible to derate them to the -A rating & take the improved time between overhauls. This is done by program pin on the Electronic Engine Control that provides N1 control once above 57%. The EICAS must also be programmed to the same derate. As stated, basic control for starting & at lower N1s is by hydro-mechanical means. RJ-700 & -900s have larger engines that do have full FADECs.
Cockpit displays are all CRT-based Rockwell-Collins Proline 4 series (thus no cockpit lighting per se needed to see the Heading). There are a total of 6, in order: PFD1,MFD1, ED1, ED2, MFD2 & PFD2. As in most glass cockpits, either MFD can be switched to be either a PFD or EICAS display in case of failure.
