In looking at photos of Boeing 737NG flight decks, I have noticed two different configurations of the primary flight instruments, as displayed on the glass displays. One configuration is a near virtual representation of what would be analog instruments, as shown in the following photos.
This is contrasted with a configuration that displays all primary flight information on one display, using speed tape and altitude tape, and navigation information on the side display, as shown in this photo.
Is the configuration of the dispaly something that can be changed by the pilot, or is it fixed for that particular airplane as determined by the operating airline’s specifications when the aircraft was first purchased?
Are there advantages to one instrumentation style versus the other?
