Robinson R22: Lesson 28 "Low Level: Part 2" (Full Lesson)

In part 2 of my low level rating, I put to practice the handling skills learned in part 1 and attempt two common maneuvers: Procedure Turns and Torque Turns. The naming nomenclature can vary depending on who you ask, but in both cases the 'runs' are conducted crosswind and only the turn itself differs.

A Procedure Turn is a turn that lets you fly low and clear obstacles on each turn. A typical use-case is when spraying crops. By varying the radius of each turn, each pass can progressively make its way up a paddock. The procedure is to start the climb with aft cyclic, then halt the climb once the obstacles are cleared with forward cyclic, turn away from the wind briefly in order to reduce the space between rows, then turn into wind to complete a 180 degree turn before applying forward cyclic to descend back to low level. The collective is barely moved as airspeed is maintained (just above translational lift at the top of the turn, 50-60kt after the dive to low level). The objective is to keep as much of the maneuver crosswind or upwind as possible, with only the slightest turn down wind when you have height on your side.

A Torque Turn similarly starts with an aft cyclic climb, however the 180 degree reversal occurs at the top of the climb just as airspeed reduces close to zero. At this point, the torque or anti-torque pedal is pressed to spin the tail around so that the turn is completed rapidly and the aircraft can start regaining the safety of airspeed as soon as possible in the dive back to low level. The direction of the turn is always into the wind, which determines which pedal to press. When turning left, ie. using the torque pedal, the collective can be raised to increase the torque imbalance and assist the turn. This should be lowered again after completion of the turn. A Torque Turn is quicker, however there is more of a 'falling' feeling especially at the top of the turn when pointed at the ground and at nearly zero airspeed!

After the lessons in the Helicopter Training Area, we proceeded to some paddocks to simulate crop spraying and general low level flying in a more realistic environment. We finished up with some Low Level autorotations which were conducted just under 500ft after a warmup.
