Normal procedures are given primarily in check-
list form and are amplified as necessary in accompa-
nying paragraph form when a detailed description of
a procedure or maneuver is required. A condensed
version of the amplified checklist, omitting all
explanatory text, is contained in the Operators and
Crewmembers Checklist, TM 55-1510-221-CL. To
provide for easier cross referencing, the procedural
steps are numbered to coincide with the correspond-
ing numbered steps in TM 55-1510-221-CL.
8-10. USE OF CHECKLIST.
Although a good working knowledge of all air-
craft procedures is desirable, it is not mandatory
that they be committed to memory. The pilot is
responsible for the initiation and accomplishment of
all required checks. Checklist items will be called
out orally and the action verified using the pilots
checklist (-CL). The copilot will normally read the
checklist and perform such duties as indicated, as
well as those directed by the pilot. As required
will not be used as a response; instead the actual
position or setting of the unit or item, such as ON
or UP or APPROACH will be stated. Upon
completion of each checklist, the copilot will advise
the pilot that the checklist called for has been com-
Items which apply only to night or only to
instrument flying shall have an "N" or I respec-
tively, immediately preceding the check to which it
is pertinent. The symbol O shall be used to indi-
cate if installed. Those duties which are the
responsibility of the copilot, at the command of the
pilot, will be indicated by a circle O around the
step number, i.e., Circuit breakers - In. The star
symbol " H " indicates an operational check contained
in the performance section of the condensed checkl-
ist. The asterisk symbol "*" indicates that perfor-
mance of the step is mandatory for all thru-flights.
The asterisk applies only to checks performed prior
to takeoff. Placarded items appear in upper case.
