Manual operation of the stabilator in flight is prohibited except…
- Stabilator emergency training
- Functional check flight requirements
- Alternate stabilator control in case of AUTO mode malfunctions
APU operating limits with engine and rotor operating
Ambient temperatures above 43 degrees C limited to 30 minutes
When do maximum airspeed, pitch and bank limits applicable for the FRIES bar?
Only for the use of the SPIE rope and personnel attached to the D-Ring.
Maximum touchdown sink rate on level terrain
300 fpm
Maximum touchdown sink rate on slopes
180 fpm
Maximum forward touchdown ground speed on level terrain
60 kts
Nose upslope limit
6 degrees
Right/left wheel upslope limit
12 degrees
How does wind affect the landing limitations?
For upslope and right/left operations will be further reduced by 2 degrees for every 5 kts of wind.
What is the ice detector calibrated to? What will happen outside these parameters?
100 KIAS
Airspeeds above 100 KIAS ice rate meter will indicate higher liquid water content than the actual conditions.
What equipment is required to be installed, operational, and turned on to fy into trace or light icing?
Windshield anti-ice
pitot heat
engine anti-ice
engine inlet anti-ice modulating valve
insulated ambient air sensing tube
What equipment is required to be installed, operational, and turned on to fly into moderate icing conditions?
Windshield anti-ice
pitot heat
engine anti-ice
engine inlet anti-ice modulating valve
insulated ambient air sensing tube
and
blade deice
Windshield anti-ice temperature limitations
Shall not be used when OAT is over 27 degrees C
Backup Hydraulic Pump Hot Weather Limits apply when the rotor is static or operating?
Static
Backup Hydraulic Pump Temperatures
-54-32
33-38
39-52
Backup Hydraulic Pump Temperatures with Operating Time and Cooldown Time
Temp
-54-32 is unlimited with zero cooldown time
33-38 is 24 minutes op time and 72 min cooldown
39-52 is 16 minutes op time and 48 min cooldown
APU operating limits with engine and rotor operating
Ambient temperatures above 43 degrees C limited to 30 minutes
APU operating limits engine and rotor NOT operating
Continuously up to 51 degrees C
What is required if the APU OIL HOT caution illuminates?
30 minutes cooldown period is required before checking oil level
What is required if the APU OIL HOT caution illuminates?
30 minutes cooldown period is required before checking oil level
What configurations can fuel be dumped in? When is it not recommended and why?
All forward airspeeds, during climbs, descents.
It is not recommended while hovering in ground effect because the fuel could recirculate and create a hazard.
Full anti-ice capability cannot be provide at what engine power levels?
10% Q per engine and below
PTO -1
Do not power up the EO?IR in temperatures below
-40 degrees C
PTO -1
When can we expect transmission oil pressure to drop?
During nose-up slop operations (because oil pumps are located forward)
PTO -1
What are the slope landing limits based on/how will the angle be measured?
It’s based on the actual slope of the terrain not the angle indicated on the attitude indicator. (Attitude indicator may show greater slope due to compression of landing gear strut.
PTO -1
When will abrupt, full pedal input be avoided?
Above 80 KIAS
PTO -1
What are bank angles limited to with PRI SERVO 1 or 2 illuminated?
30 degrees
PTO -1
Limits with rearward flight and downwind hovering
Why?
Prolonged operations are to be avoided to prevent accumulation of exhaust fumes in the helicopter and heat damage to windows on open cargo doors.
PTO -1
Limits with simulating stabilator automatic mode failure
Stabilator shall only be slewed in the trailing edge up direction.
PTO -1
How will a fully developed blade stall present itself?
heavy 4 per revolution vibration
increasing Q
loss of altitude
PTO -1
Which turn direction (right vs left) will take more time to recover from?
Right
PTO -1
Limitation with Stab auto mode failure
Do not exceed the airspeed indicator variable VNE red arc
PTO -1
CAUTION With opening cabin doors
Crewmembers must have full control of the cabin door when opening or closing it.
PTO -1

120%
PTO -1
CAUTION with Engine start limitation pressure altitude
Engine start attempts at or above a pressure altitude of 18,000’ could result in a hot start.
PTO -1
When does the starter limitation rest period timing start?
When the first attempt is aborted for any reason (it applies regardless of the duration of the first attempt).
