Which aircraft manufacturers still include Vertical Situation Displays (VSD) feature in their cockpits?
VSD

Boeing have a patent on a VSD (Vertical Situation Display), which is part of the Honeywell EGPWS (Enhanced Ground Proximity Warning System) which first appeared as an option on 737s about twelve years ago I think.


  The system will be offered by early 2003 as a customer option on in-production 737s and by retrofit on 737-600/-700/-800/-900 airplanes already in service. Implementation of the system on other Boeing models is under consideration.

I don't know if Boeing offer licences at acceptable terms to their competitors, or if Honeywell make available, to other aircraft makers, products that incorporate features licensed from those patents.

CFIT

It is possible that other manufacturers have equivalent options for alerting pilots of potential CFIT (Controlled Flight Into Terrain).

TAWS &amp; EGPWS

The FAA, for example, requires aircraft be fitted with systems that comply with TAWS (Terrain Awareness Warning Systems) requirements. EGPWS systems satisfy that requirement.

TAWS requires a terrain awareness display but I dont think it requires something specifically like Boeing's VSD.

Airbus for example, on at least their A350 and A380 models, have a navigation display that incorporates "vertical flightpath data". I guess they don't call it a VSD. They also have what I think is a fairly common type of terrain display showing "peaks" ahead of the aircraft.

RNP

It may be that some of the issues addressed by the VSD are, for many airports in mountainous terrain, taken care of by RNP (Required Navigation Performance) which prescribes the required navigational accuracy of the aircraft's navigation systems. Generally the aircraft is required to be able to follow an approach path that consists of a sequence of curved three-dimensional paths to the runway that avoids terrain. I imagine this path is pre-programmed into the navigation systems along with the go-around paths.
