From the previous chapters, it should be apparent that
no two helicopters perform the same way. Even when
flying the same model of helicopter, wind, temperature,
humidity, weight, and equipment make it difficult to
predict just how the helicopter will perform. Therefore,
this chapter presents the basic flight maneuvers in a
way that would apply to a majority of the helicopters.
In most cases, the techniques described apply to small
training helicopters with:
• A single, main rotor rotating in a counterclockwise
direction (looking downward on the rotor).
• An antitorque system.
Where a technique differs, it will be noted. For example,
a power increase on a helicopter with a clockwise rotor
system requires right antitorque pedal pressure instead
of left pedal pressure. In many cases, the terminology
“apply proper pedal pressure” is used to indicate both
types of rotor systems. However, when discussing throttle
coordination to maintain proper r.p.m., there will be
no differentiation between those helicopters with a governor
and those without. In a sense, the governor is doing
the work for you. In addition, instead of using the terms
collective pitch control and the cyclic pitch control
throughout the chapter, these controls are referred to as
just collective and cyclic.
Because helicopter performance varies with different
weather conditions and aircraft loading, specific nose
attitudes and power settings will not be discussed. In
addition, this chapter does not detail each and every
attitude of a helicopter in the various flight maneuvers,
nor each and every move you must make in order to
perform a given maneuver.
When a maneuver is presented, there will be a brief
description, followed by the technique to accomplish
the maneuver. In most cases, there is a list of common
errors at the end of the discussion.
PREFLIGHT
Before any flight, you must ensure the helicopter is
airworthy by inspecting it according to the rotorcraft
flight manual, pilot’s operating handbook, or other
information supplied either by the operator or the manufacturer.
Remember that as pilot in command, it is
your responsibility to ensure the aircraft is in an airworthy
condition.
In preparation for flight, the use of a checklist is important
so that no item is overlooked. Follow the manufacturer’s
suggested outline for both the inside and outside inspection.
This ensures that all the items the manufacturer
feels are important are checked. Obviously, if there are
other items you feel might need attention, inspect
them as well.
