Dear fellows
There are two tipes of LCD presentations on the 737NG:
1. "Glass Cockpit", similar to that of the Boeing 777;
2. "Traditional", similar to the instrument positions of the 737 "Classic".
The 2. allows a common type rating with the 737 "Classic" (unless in Brazil).
On the 1. option, the Lower DU may present, other than engine indications (ENG button on MFD), systems indications (SYS button on MFD) - standard Hydraulics, optional Flight surfaces and/or Brake temperatures.
Some airlines uses the Lower DU only as backup, keeping it without any information during normal operation.
In Brazil, VARIG and Gol use the 2. option. At VARIG, the same flight crew flies the 737 "Classical" and the 737NG.
Best regards
