For anyone involved in putting in new displays, have you seen the Marinvent Dynamic Non-Linear Displays? The whole airspeed range from stall to past VNE is shown, and the whole altitude scale from below sea level to the service ceiling is displayed. Situational awareness is improved, and any hard altitude clearance limits are continuously in view.
If anyone wants more info, PM me - I've got a copy of their brochure on DNLD.
