The Handbook
This Pilot’s Operating Handbook has been prepared using GAMA
Specification #1 for Pilot’s Operating Handbook, Revision 2, dated 18
October 1996 as the content model and format guide. However, some
deviations from this specification were made for clarity. The Handbook
is presented in loose-leaf form for ease in inserting revisions and is
sized for convenient storage. Tabbed dividers throughout the
Handbook allow quick reference to each section. Logical and
convenient Tables of Contents are located at the beginning of each
section to aid in locating specific data within that section. The
Handbook is divided into ten sections as follows:
Section 1................................................................................... General
Section 2...............................................................................Limitations
Section 3.......................................................... Emergency Procedures
Section 4.................................................................Normal Procedures
Section 5................................................................... Performance Data
Section 6...........................................Weight & Balance/Equipment List
Section 7............................................. Airplane & Systems Description
Section 8........................................Handling, Servicing & Maintenance
Section 9...........................................................................Supplements
Section 10.................................................................Safety Information
The data presented in this Handbook is the result of extensive flight
tests and is approved by the Federal Aviation Administration. However,
as new procedures or performance data are developed, they will be
sent to the owner of record for each airplane.
• Note •
It is the responsibility of the owner to ensure that the Pilot’s
Operating Handbook is current at all times. Therefore, it is
very important that all revisions be properly incorporated into
this Handbook as soon as they are received.

Revising the Handbook
Two types of revisions may be issued for this Handbook: Numbered
and Temporary.
Temporary revisions are printed on yellow paper, normally cover only
one topic or procedure, and are issued to provide safety related
information or other time sensitive information where the rigor of
providing a numbered revision is not possible in the time allowed. All
the information needed to properly file a temporary revision is included
on the revision itself. Typically, a temporary revision is superseded and
replaced by the next numbered revision. A “Log of Temporary
Revisions” following the “List of Effective Pages” is provided to log
temporary revisions when they are issued. Typically, the “Log of
Temporary Revisions” is replaced at the next numbered revision.
Numbered revisions are printed on white paper, normally cover
several subjects, and are issued as general updates to the Handbook.
Each numbered revision includes an “Instruction Sheet,” a “List of
Effective Pages”, and a “Revision Highlights” page. The “Instruction
Sheet” is intended to assist the manual holder in removing superseded
pages and inserting new or superseding pages. The “List of Effective
Pages” shows the issue or revision status of all pages in the
Handbook. The “Revision Highlights” page gives a brief description of
changes made to each page in the current revision.
Identifying Revised Material
Each page in the Handbook has revision identification at the lower
inside corner opposite the page number. Original issue pages will be
identified by the words “Original Issue” at this location. In the event
that the majority of pages in the Handbook are revised, Cirrus may
determine that it is more effective to reissue the Handbook. Reissued
pages will be identified by the word “Reissue” followed by a letter
indicating the reissue level; for example, “Reissue A” Revised pages
will be identified by the word “Revision” followed by the revision
number at this location; for example, “Revision 2” (Original Issue,
Revision 2) or “Revision B1” (Reissue B, Revision 1).
Revised material on a page can be identified by a change bar located
at the outside page margin. See the outside margin of this page
adjacent to this paragraph for an example. Revision bars are not used
at reissues of the Handbook.

Supplements
The Supplements section (Section 9) of this Handbook contains FAA
Approved Supplements necessary to safely and efficiently operate the
SR20 when equipped with optional equipment not provided with the
standard airplane or not included in the Handbook. Supplements are
essentially “mini-handbooks” and may contain data corresponding to
most sections of the Handbook. Data in a supplement either adds to,
supersedes, or replaces similar data in the basic Handbook.
Section 9 includes a “Log of Supplements” page preceding all Cirrus
Design Supplements produced for this airplane. The “Log of
Supplements” page can be utilized as a “Table of Contents” for Section
9. If the airplane is modified at a non Cirrus Design facility through an
STC or other approval method, it is the owner’s responsibility to
ensure that the proper supplement, if applicable, is installed in the
Handbook and that the supplement is properly recorded on the “Log of
Supplements” page.

VXBest Angle of Climb Speed is the speed which results in the
greatest gain of altitude in a given horizontal distance.
VYBest Rate of Climb Speed is the speed which results in the
greatest gain of altitude in a given time.
IMC Instrument Meteorological Conditions are meteorological
conditions expressed in terms of visibility, distance from
cloud, and ceiling less than the minima for visual flight
defined in FAR 91.155.
ISA International Standard Atmosphere (standard day) is an
atmosphere where (1) the air is a dry perfect gas, (2) the
temperature at sea level is 15°C, (3) the pressure at sea
level is 29.92 in.Hg (1013.2 millibars), and (4) the

the temperature is -56.5°C is -0.00198°C per foot and zero
above that altitude.
MSL Mean Sea Level is the average height of the surface of the
sea for all stages of tide. In this Handbook, altitude given as
MSL is the altitude above the mean sea level. It is the
altitude read from the altimeter when the altimeter’s
barometric adjustment has been set to the altimeter setting
obtained from ground meteorological sources.
OAT Outside Air Temperature is the free air static temperature
obtained from inflight temperature indications or from ground
meteorological sources. It is expressed in either degrees
Celsius or degrees Fahrenheit.
• Pressure Altitude is the altitude read from the altimeter
when the altimeter’s barometric adjustment has been set to
29.92 in.Hg (1013 mb) corrected for position and instrument

Weight and Balance Terminology
• Unusable Fuel is the quantity of fuel that cannot be safely
used in flight.
• Usable Fuel is the fuel available for flight planning.
c.g. Center of Gravity is the point at which an airplane would
balance if suspended. Its distance from the reference datum
is found by dividing the total moment by the total weight of
the airplane.
•Armis the horizontal distance from the reference datum to
the center of gravity (c.g.) of an item. The airplane’s arm is
obtained by adding the airplane’s individual moments and
dividing the sum by the total weight.
• Basic Empty Weight is the actual weight of the airplane
including all operating equipment that has a fixed location in
the airplane. The basic empty weight includes the weight of
unusable fuel and full oil.
MAC Mean Aerodynamic Chord is the chord drawn through the
centroid of the wing plan area.
LEMAC Leading Edge of Mean Aerodynamic Chord is the forward
edge of MAC given in inches aft of the reference datum
(fuselage station).
• Maximum Gross Weight is the maximum permissible
weight of the airplane and its contents as listed in the aircraft
specifications.
•Momentis the product of the weight of an item multiplied by
its arm.
•UsefulLoadis the basic empty weight subtracted from the
maximum weight of the aircraft. It is the maximum allowable
combined weight of pilot, passengers, fuel and baggage.
• Station is a location along the airplane fuselage measured
in inches from the reference datum and expressed as a
number. For example: A point 123 inches aft of the reference
datum is Fuselage Station 123.0 (FS 123).
