INSTRUMENT FLIGHT MANEUVERS - HELICOPTER
4.1. Application. This section outlines techniques for accomplishing commonly used flight
maneuvers in helicopters. Any instrument flight, regardless of how long or complex, is
simply a series of connected basic flight maneuvers as illustrated in Figure 4.1. Failure to
consider each portion of the flight as a basic instrument maneuver often leads to erratic
aircraft control. The maneuvers that are described here are general in nature; therefore, slight
variations may be required for specific helicopters and in-flight situations. The degree of
proficiency developed while accomplishing the maneuvers outlined will allow you to execute
any variation or additional maneuver. The information received from the navigation
instruments or an air traffic controller should be considered as advising you what maneuver
to perform, when to perform it, or what adjustments, if any, are required. Instrument
approach procedure charts and similar publications should be considered as pictorial
presentations of a series of connected instrument flight maneuvers. Keeping these
considerations in mind and calling upon previous experience, you will find that you are
always performing a familiar maneuver. By visualizing the next maneuver, you can plan
ahead and know exactly what crosscheck and aircraft control techniques to employ.

4.2. The Instrument Takeoff. The ITO is accomplished by referring to outside visual
references and to the flight instruments. The amount of attention given to each reference
varies with the individual, the type of aircraft, and existing weather conditions. The ITO is a
composite visual and instrument takeoff when conditions permit, and should not be confused
with a "hooded takeoff." The ITO procedures and techniques are invaluable aids during
takeoffs at night, toward and over water or deserted areas, and during periods of reduced
