I wonder what the TCAS diplay is in a NG fitted with PFD/ND. I understand they have altitude tape and VSI pointer. Do you guys have it 777 like or the old style?
The PFD/ND style of the 737NG is similar to that of the 777. It is okay, except for the vertical speed indication, which is so narrow that it actually hinders accurate V/S read-out. I believe the same insane lay-out is used by Airbus, and Fokker, which have all tried to squeeze the old style round VSI into a narrow vertical window on the PFD. A much better solution is the vertical V/S arrow used for the MD-11 PFD.
The RA information for a 737NG is a combination of a truncated V-bar in the attitude indication, showing the pitch angles to avoid, and a red tape in the V/S indication, showing the V/S values to avoid. (The old style display uses the same indications, except it also includes a green fly-to V/S arc on the VSI. The MD-11 doesn't offer any pitch indications, but it does show red and green area's on the vertical speed tape. Since its V/S display is so much clearer than the Boeing/Airbus solution, this works equally well.)
