Slope Cautions & Notes
CAUTION - When performing slope landings with
_______, ensure _______.
NOTE - Because of the___of the main transmission and forward location of both transmission oil pumps,____ will drop during ___slope operations. At a slope angle of_, an indicated oil pressure of_to _ is normal; and at a _ slope angle, a pressure in the range of _ to _ is normal due to pitching of the helicopter.
NOTE - The ____ may intermittently light when the helicopter returns to a ___ attitude after extended operation at __ attitudes with fuel boost pumps off. This may also occur during a __ to high altitude followed by a ___ maneuver. If the light extinguishes immediately, ___ is required by the pilot.
CAUTION - When performing slope landings with
external fuel tanks, ensure tank to ground clearance.
NOTE - Because of the flat profile of the main transmission and forward location of both transmission oil pumps, transmission oil pressure will drop during nose-up slope operations. At a slope angle of 10º, an indicated oil pressure of 30 to 35 psi is normal; and at a 15º slope angle, a pressure in the range of 10 to 15 psi is normal due to pitching of the helicopter.
NOTE - The low fuel pressure indicator light(s) may intermittently light when the helicopter returns to a neutral or positive attitude after extended operation at nose down attitudes with fuel boost pumps off. This may also occur during a climb to high altitude followed by a pitch-up maneuver. If the light extinguishes immediately, no action is required by the pilot.
