Because of obstacle B, the gradient cannot be reduced to 3.3% (2.5% + 0.8%) (CAT H, 5.0%) just after passing obstacle A.
The altitude/height or fix at which a gradient in excess of 3.3% (CAT H, 5.0%) is no longer required is promulgated in
the procedure.
Obstacles A and B will be promulgated. Mountain promulgated on Aerodrome Obstacle Chart Type C.
