What is minimum eye height over threshold?
What is minimum eye height over threshold? The MEHT [minimum eye height over the threshold] is the sum of MWC [Minimum wheel clearance] and EWH [Eye-to-wheel height] of airplane in landing configuration. ( See belo) MEHT = MWC + EWH. In the first illustration we can see 4 different groups of “Eye to wheel height”, which depend by the type of aircraft.
What is the minimum height above which all aircraft should fly?
The Federal Aviation Regulation (FAR) Part 91.119 indicates that, except when necessary for departure or landing, the minimum altitude over urban areas is 1,000 feet above ground level (AGL) and 500 feet AGL over rural areas.
