Purpose: To transition from flight at altitude to a stabilized 3-5 foot hover using a steeper than normal approach angle. Demonstrates obstacle clearance.
Note: Prior to performing this maneuver, pilot(s) should become familiar with Safety Notice SN-22.
|Cyclic:||Airspeed; Ground Track; Rate of Closure|
|Collective:||Rate of Descent; Angle of Approach|
|Pedals||Trim (Above 50 ft AGL); Heading (Below 50 ft AGL)|
On Final approach, the aircraft should be headed into the wind and aligned with the intended point of touch down. The pilot will maintain 60 KIAS and 300 feet AGL until a normal approach angle is achieved.
When a normal approach angle is intercepted, reduce forward speed forward airspeed to 40-45 KIAS in order to intercept a steep approach angle.
The collective much be reduced a greater amount once the angle is intercepted in order to maintain the steep approach angle. Right pedal my be needed in order to compensate for the reduction of power.
Maintain the approach angle and rate of descent no great than 300 FPM with the collective, rate of closure with the cyclic, and trim with the pedals. Loss of ETL will occur at higher altitude during a steep approach requiring an increase of collective sooner than normal to prevent settling.
Terminate at a 3-5 foot stabilized hover.
Note: Special consideration must be made to ensure the aircraft does not gain a descent rate great than 300 fpm with airspeed less than 30 KTS!
