SECTION 9. Advanced Flight Maneuvers

1 Reconnaissance Procedures

Reconnaissance procedures are used to gather more information about an unfamiliar site, particularly an off-airport site, before attempting a landing.

1.1 High Reconnaissance

The goal of high reconnaissance is to gather information about a site including wind direction and speed, identify a suitable touchdown site, identify a suitable approach path and suitable abort paths, and identify any obstacles in the area that might present a hazard. The pilot should also consider potential emergency landing spots in the event of an engine failure during the approach.

High reconnaissance should be conducted at high enough altitude to have a good view of the planned landing area, as well as be able to make an emergency landing in the event of an emergency. Fly a circular path around the planned landing area that is at about a 45 degree angle from the helicopter (see SECTION 8. Basic Flight Maneuvers - Turns_Around_a_Point). Evaluate the landing area during the maneuver, but do not become so focused on the landing area that you lose situational awareness on the aircraft.

2 Maximum Performance Takeoffs

If takeoff is from a confined area, the max performance takeoff procedure can be used. Begin with helicopter on the ground and collective full down. Raise collective until manifold pressure is at 29 inches (red line) while applying slight forward cyclic to begin forward movement. When clear of the obstacle apply additional forward cyclic. Once ETL is reached at about 30 mph, continue climb as normal.

4 Steep Approaches

A steep approach can be used when landing is to a confined area. Follow the same procedure as for a normal landing, but slow to 30 mph and maintain that speed through the descent.
