Student practice (dual only) TIPS FOR INSTRUCTORS Training accidents that involve striking the tail with the main rotor blades during an autorotational landing are very frequent. These can generally be avoided by the instructor ensuring that the cyclic is not moved after, during or immediately after touchdown. There is a need for the instructor to follow through on the controls during autorotational landings. Take care that you do not make the exercise worthless by inadvertently leading, rather than following, through. This exercise should be practised only in areas known to be safe and suitable for landing. The student should practise autorotations in as many varied conditions as possible, because the type of autorotative flare will vary. Varying conditions include the area available, size, surface, wind and obstacle clearance. Both zero-speed and run-on touchdowns should be practised and the student taught when to employ each technique. This is a stressful and demanding exercise for both student and instructor. Resist the temptation to attempt ‘just one more’ at the end of the lesson, as you will usually find the student’s performance will get worse, not better. Brief the student on the school’s policy on autorotations to touchdown. Most schools do NOT allow them to be practised solo. 15 AUTOROTATIVE VARIABLES GROUND SCHOOL Aim For the student to learn how to vary range in autorotation. Review Entry to Autorotation and power terminated/touchdown autorotations Autorotational flight envelope, including airspeed and rotor RPM limitations Effects of airspeed on range and rate of descent in autorotation Motivation Autorotation at the manufacturer’s recommended airspeed is the ideal. It is vital, that the student be capable of taking full advantage of the helicopter’s capabilities in autorotation to reach the intended landing spot. Airmanship ? Safety checks |
