? Hover-taxi
State the height and ground speed to be used, and relate them to the safety considerations.
Describe the effects of the controls.
AIR EXERCISE
Hovering turns
Demonstrate 360° hovering turns in each direction, commencing into the wind and pausing at each 90° point.
Student practice Hover-taxi
Demonstrate hover-taxiing into the wind.
Student practice
Demonstrate hover-taxiing out of the wind.
Student practice
TIPS FOR INSTRUCTORS
Dual instruction in this exercise should be carried out in a wide range of wind conditions. This will prevent the situation arising where the dual instruction is given on a calm day and the student meets the problems of strong winds when solo on another.
Pausing at each cardinal point enables the instructor to point out the different cylic positions into the wind; when the student is competent, complete the 360° turn without pause.
Whenever possible, when hover-taxiing, keep the skids parallel to the helicopter movement in case of engine failure or the need to run the helicopter onto the ground in an aft C of G condition.
Turns around the tail are covered separately in Exercise 10.
Sometimes the student will use cyclic instead of pedal to help turn the helicopter, particularly in strong winds.
When the student is proficient at the basics, introduce some hover patterns requiring taxiing and pedal turns.
09
SIDEWAYS AND REARWARDS FLIGHT
GROUND SCHOOL POINTS
Aim
For the student to learn:
? sideways and rearwards flight facing into and out of the wind
? turns about the tail and nose.
Review
Hovering exercises: Exercise 7, 8 and 9 Motivation
Sideways and rearwards flight and turns about the tail form important parts of helicopter operations, often in among obstructions.
Airmanship
Lookout: obstacles Helicopter limitations
Teaching Points
Point out that it is preferable to hover-taxi forwards rather than sideways or rearwards if at all possible. This is because of lookout and engine failure considerations.
