c. REDUCED VERTICAL SEPARATION MINIMUM FLIGHT LEVEL ALLOCATION SCHEME - The following flight level allocation scheme should be used by operators for flight planning purposes:
(1)
May be flight planned for both E and W non-FL430 RVSM certified aircraft - 24 hours a day
FL410  E flight level - 24 hours per day
FL400  W flight level - except within E other than scheduled
FL390  E flight level - except within W other than scheduled
FL380*  W flight level - except within E other than scheduled
FL370  E flight level - except within W other than scheduled
FL360*  W flight level - except within E other than scheduled
FL350*  E flight level - except within W other than scheduled
FL340  W flight level - except within E other than scheduled
FL330*  E flight level - except within W other than scheduled
FL320*  W flight level - except within E other than scheduled
FL310*  E flight level - except within W other than scheduled
FL300  W flight level - 24 hours per day
FL290 and
below  Even levels W - 24 hours Odd levels E - 24 hours per day per day
(2)
Flight Level*: Shanwick/Gander may exchange on a tactical basis during other than scheduled periods.
