f. Asterisked Checks. An asterisk (*) prior to a check
requires that the test flight check sheet be annotated with a
specific reading. Also, a check mark
for satisfactory per-
formance, or an (X) for problem detected will be recorded and
a short statement entered in the remarks block of the Check
g. An (O) prior to a check indicates a requirement if the
equipment is installed.
h. Maintenance Test Flight Check Sheet. The check
sheet contained in Section V will be used for all test flights.
When a test flight is performed to determine if specific equip-
ment or systems are operating properly, completion of only
that portion of the maintenance test flight check sheet appli-
cable to the specific equipment or systems being tested is
required. The aircraft test flight check sheets may be locally
reproduced. Continuation sheets may be used when necessary.
Items that prove to be unsatisfactory during the test flight and
require corrective action shall be listed in the remarks block
during flight and transferred to DA Form 2408-13-1 immedi-
ately after termination of the flight. The sheet will be attached
to the DA Form 2408-13-1 upon completion. After accumula-
tion of two or more sheets, the data should be reviewed to
determine if trends are developing.
i. Free Air Temperature (FAT) and Outside Air Tem-
perature (OAT). For the purposes of this manual, free air
temperature (FAT) is to be considered the same as outside air
j. Effectivity Codes. The designator symbol
used throughout this manual to identify text, illustrations, and
performance data for aircraft equipped with the Improved
Constant Area Exhaust Stacks. The designator symbol
identifies text, illustrations, and performance data for aircraft
equipped with the Infra Red Reducing Exhaust Stacks. Data
which has no icons applies to both.
