Rotorcraft Flying Handbook, FAA-H-8083-21

These charts, graphs, and tables vary in style but all
contain the same basic information. Some examples
of the performance information that can be found in
most flight manuals include a calibrated versus indicated
airspeed conversion graph, hovering ceiling
versus gross weight charts, and a height-velocity diagram.
[Figure 6-7] For information on how to use the
charts, graphs, and tables, refer to Chapter 8—
Performance.

ers should describe the systems in a manner that is
understandable to most pilots. For larger, more complex
rotorcraft, the manufacturer may assume a higher
degree of knowledge. (For more information on rotorcraft
systems, refer to Chapter 5—Helicopter Systems
and Chapter 18—Gyroplane Systems.)
HANDLING, SERVICING, AND
MAINTENANCE
The Handling, Servicing, and Maintenance section
describes the maintenance and inspections recommended
by the manufacturer, as well as those required
by the regulations, and Airworthiness Directive (AD)
compliance procedures. There are also suggestions on
how the pilot/operator can ensure that the work is done
properly.

This section also describes preventative maintenance
that may be accomplished by certificated pilots, as
well as the manufacturer’s recommended ground handling
procedures, including considerations for
hangaring, tie down, and general storage procedures
for the rotorcraft.
SUPPLEMENTS
The Supplements Section describes pertinent information
necessary to operate optional equipment installed on
the rotorcraft that would not be installed on a standard
aircraft. Some of this information may be supplied by the
aircraft manufacturer, or by the maker of the optional
equipment. The information is then inserted into the
flight manual at the time the equipment is installed.

GROSS WEIGHT ~ LBS
Figure 6-7. One of the performance charts in the Performance
Section is the “In Ground Effect Hover Ceiling versus Gross
Weight” chart. This chart allows you to determine how much
weight you can carry and still operate at a specific pressure
altitude, or if you are carrying a specific weight, what is your
altitude limitation.
SAFETY AND OPERATIONAL TIPS
The Safety and Operational Tips is an optional section
that contains a review of information that could
enhance the safety of the operation. Some examples of
the information that might be covered include: physiological
factors, general weather information, fuel conservation
procedures, external load warnings, low rotor
r.p.m. considerations, and recommendations that if not
adhered to could lead to an emergency.
WEIGHT AND BALANCE
The Weight and Balance section should contain all the
information required by the FAA that is necessary to
calculate weight and balance. To help you correctly
compute the proper data, most manufacturers include
sample problems. (Weight and balance is further discussed
in Chapter 7—Weight and Balance.)
AIRCRAFT AND SYSTEMS
DESCRIPTION
The Aircraft and Systems Description section is an
excellent place to study and familiarize yourself with
all the systems found on your aircraft. The manufactur-
Airworthiness Directive (AD)—A
regulatory notice that is sent out
by the FAA to the registered owners
of aircraft informing them of
the discovery of a condition that
keeps their aircraft from continuing
to meet its conditions for airworthiness.
Airworthiness
Directives must be complied with
within the required time limit, and
the fact of compliance, the date of
compliance, and the method of
compliance must be recorded in
the aircraft maintenance records.
