Definition
Eye to Wheel Height (EWH) is defined as the highest expected vertical distance from the pilot’s eyes to the lowest portion of the aircraft at threshold crossing with maximum certificated landing weight in the normal landing configuration for the aircraft type.
Note: It is of importance to realise that this is not the physical dimension of the aircraft when at rest on the apron. Eye to Wheel Height is the vertical distance from the pilot's eyes to the bottom of the lowest wheels, whilst in the landing configuration, at threshold crossing height and speed, and at the normal pitch attitude for the glideslope angle. The EWH is normally reported for a 3 degree glideslope, but may differ for other glideslopes.

Accidents and Incidents
- GL5T, Fox Harbour NS Canada, 2007 'On 11 November 2007, a Bombardier BD-700 (Global 5000) operated by Canadian charter company Jetport touched down short of the runway at destination Fox Harbour in normal daylight visibility and then directional control was lost and the aircraft exited the side of the runway ending up having rotated 120° clockwise about its fore-aft axis and came to rest approximately 300metres from the threshold and approximately 50 meters from the runway edge. As a result, the co pilot and one of the passengers suffered serious injuries and the other eight occupants suffered minor injuries. The aircraft sustained major structural damage'
