✔✔what is MORA? - ✔✔Minimum Off Route Altitude - two types of MORA, Grid and
Route
Grid MORA - Defined by the Lat and Long lines on the chart.
-Government charts - provide 1000 feet of obstacle clearance in non-mountainous
terrain and 2000 feet of obstacle clearance in mountainous terrain.
-Jeppesen charts - provides terrain and man-made structure clearance of 1000 feet in
areas where the highest elevations are 5000 feet msl and below. provides terrain and
man-made structure clearance of 2000 feet in areas where the highest elevation is
above 5000 feet msl.
Route MORA - Defined by a distance of 10nm either side of an airway and a 10nm cap
on both ends.
Jeppessen Charts Only - Provides 1000 feet of obstacle clearance when operating at
5000 feet or lower msl . Provides 2000 feet of obstacle clearance when operating above
5000 feet msl
