Grid MORA
Hi all, i have a little doubt about the grid MORA.
I know that this altitude provides 1000/2000 ft of obstacle clearance if there are obstacle with an elevation less/more that 5000 ft; since this is an altitude we have to use the QNH and if there are more aerodromes within the same grid which QNH do we have to set ? the nearest to us or the lower in the grid ?
Should we correct this altitude by the temperature error ?
Thank's a lot in advance
