What does Land Immediately mean in emergency procedures?
Land on the nearest clear area where a safe normal landing can be performed
Be prepared to enter autorotation during approach, if required.
What does Land as soon as practical indicate?
Landing site is at pilot’s discretion based on nature of problem and available landing areas
Flight beyond nearest airport is not recommended.
What may indicate a power failure?
A power failure may be caused by either an engine or drive system failure.
In case of power failure, what should you do immediately?
Lower collective to enter autorotation and reduce airspeed to power-off Vne or below
Aft cyclic is required when collective is lowered at high airspeed.
What should you not apply during touchdown or ground slide to prevent possible blade strike to tailcone?
Aft cyclic
This caution is important to avoid damage during landing.
What is the first step to take during a power failure above 500 feet AGL?
Lower collective immediately to maintain rotor RPM
This action helps to prevent rotor RPM from dropping too low.
At what airspeed should a steady glide be established during a power failure above 500 feet AGL?
Approximately 70 KIAS
This speed is optimal for maximum glide distance or minimum rate of descent.
Between which percentages should the rotor RPM be maintained between during a power failure above 500 feet AGL?
97 and 108%
If light weight prevents attaining above 97%, apply full down collective.
What is the recommended action regarding the landing spot during a power failure above 500 feet AGL?
Select landing spot and maneuver into wind if altitude permits
This helps ensure a safer landing approach.
When can a restart be attempted during a power failure above 500 feet AGL?
At pilot’s discretion if sufficient time is available
Refer to the ‘Air Restart Procedure’ for more details.
What should be done with unnecessary switches and the fuel valve if unable to restart during a power failure above 500 feet AGL?
Turn unnecessary switches and fuel valve off
This helps to prevent any potential hazards during landing.
What action should be taken at about 40 feet AGL during a power failure above 500 feet AGL?
Begin cyclic flare to reduce rate of descent and forward speed
This maneuver prepares the aircraft for landing.
What should be done at about 8 feet AGL during a power failure above 500 feet AGL?
Apply forward cyclic to level ship and raise collective just before touchdown
This cushions the landing and ensures a level attitude.
What is the first step to take during a power failure between 8 feet and 500 feet AGL?
Lower collective immediately to maintain rotor RPM
This is crucial to prevent rotor RPM from dropping.
What should the rotor RPM be maintained between during a power failure between 8 feet and 500 feet AGL?
97 and 108%
If light weight prevents attaining above 97%, apply full down collective.
What should be maintained until ground is approached during a power failure between 8 feet and 500 feet AGL?
Airspeed
This is important for controlling descent and landing.
What should be done at about 8 feet AGL during a power failure between 8 feet and 500 feet AGL?
Apply forward cyclic to level ship and raise collective just before touchdown
This action helps cushion the landing.
What should you do to prevent yawing during a power failure below 8 feet AGL?
Apply right pedal as required
This action helps maintain control of the rotorcraft during descent.
During a power failure below 8 feet AGL, what should you do to cushion landing?
Raise collective just before touchdown
This technique helps soften the impact during landing.
What is the airspeed for maximum glide distance configuration?
Approximately 90 KIAS
This speed optimizes the glide performance of the rotorcraft.
What is the rotor RPM for maximum glide distance configuration?
Approximately 90%
Maintaining this rotor RPM is crucial for efficient gliding.
What is the best glide ratio for maximum glide distance configuration?
About 4.7:1 or one nautical mile per 1300 feet AGL
This ratio indicates the efficiency of the glide in terms of distance covered.
What is the airspeed for minimum rate of descent configuration?
Approximately 55 KIAS
This speed is essential for achieving the lowest rate of descent.
What is the minimum rate of descent in feet per minute for minimum rate of descent configuration?
About 1350 feet per minute
This rate is critical for controlled descent during autorotation.
