The following slope limitations apply regardless of gross weight or CG, with or without ESSS/ERFS.
- CAUTION When performing slope landings with External Extended Range Fuel System Tanks, ensure tank to ground clearance.
a. 15° nose-up, right wheel up or left wheel upslope. The slope limitations shall be further reduced by 2° for every 5 knots of wind.
c. The main gearbox may be operated up to 30 minutes at a time with pressure fluctuations when the helicopter is known to be at a nose-up attitude (i.e., slope landings or hover with extreme aft CG).
d. When attempting a nose upslope landing at gross weights in excess of 16,000 pounds with skis installed, the parking brake may not hold the helicopter in position. The pilot should be prepared to use the toe brakes.
e. Slope landings with skis installed are limited to 10° nose-up and right wheel or left wheel upslope. The slope limitation shall be further reduced by 2° for every 5 knots of wind above 12 knots.
