Pt. 63, App. A
(3) When the test is conducted with an air-
craft belonging to an air carrier, the naviga-
tion procedures should conform with those
set forth in the carrier’s operations manual.
Items of the flight test which are not per-
formed during the routine navigation of the
flight will be completed by oral examination
after the flight or at times during flight
which the applicant indicates may be used
for tests on those items. Since in-flight
weather conditions, the reliability of the
weather forecast, and the stability of the air-
craft will have considerable effect on an ap-
plicant’s performance, good judgment must
be used by the agent or examiner in evalu-
ating the tests.
(d)
Ground test. For the ground test, in the
order of the numbered items on the examina-
tion check sheet, an applicant will be re-
quired to:
(1) Identify without a star identifier, at
least six navigational stars and all planets
available for navigation at the time of the
examination and explain the method of iden-
tification.
(2) Identify two additional stars with a star
identifier or sky diagrams and explain iden-
tification procedure.
(3) Precompute a time-altitude curve for a
period of about 20 minutes and take 10 single
observations of a celestial body which is ris-
ing or setting rapidly. The intervals between
observations should be at least one minute.
Mark each observation on the graph to show
accuracy. All observations, after corrections,
shall plot within 8 minutes of arc from the
time-altitude curve, and the average error
shall not exceed 5 minutes of arc.
(4) Take and plot one 3-star fix and 3 LOP’s
of the sun. Plotted fix or an average of LOP’s
must fall within 5 miles of the actual posi-
tion of the observer.
(5) Demonstrate or explain the compensa-
tion and swinging of a liquid-type magnetic
compass.
(6) Demonstrate or explain a method of
aligning one type of drift meter.
(7) Demonstrate or explain a method of
aligning an astro-compass or periscopic sex-
tant.
(e)
Flight test. For the flight test, in the
order of the numbered items on the examina-
tion check sheet, an applicant will be re-
quired to:
(1) Demonstrate his ability to read weather
symbols and interpret synoptic surface and
upper air weather maps with particular em-
phasis being placed on winds.
(2) Prepare a flight plan by zones from the
forecast winds or pressure data of an upper
air chart and the operator’s data.
(3) Compute from the operator’s data the
predicted fuel consumption for each zone of
the flight, including the alternate.
(4) Determine the point-of-no-return for
the flight with all engines running and the
equitime point with one engine inoperative.
Graphical methods which are part of the
company’s operations manual may be used
for these computations.
(5) Prepare a cruise control (howgozit)
chart from the operator’s data.
(6) Enter actual fuel consumed on the
cruise control chart and interpret the vari-
ations of the actual curve from the predicted
curve.
(7) Check the presence on board and oper-
ating condition of all navigation equipment.
Normally a check list will be used. This
check will include a time tick or chronom-
eter comparison. Any lack of thoroughness
during this check will justify this item being
graded unsatisfactory.
(8) Locate emergency equipment, such as,
the nearest fire extinguisher, life preserver,
life rafts, exits, axe, first aid kits, etc.
(9) Recite the navigator’s duties and sta-
tions during emergencies for the type of air-
craft used for the test.
(10) Demonstrate the proper use of a flux
gate compass or gyrosyn compass (when
available), with special emphasis on the cag-
ing methods and the location of switches,
circuit breakers, and fuses. If these com-
passes are not part of the aircraft’s equip-
ment, an oral examination will be given.
(11) Be accurate and use good judgment
when setting and altering headings. Erro-
neous application of variation, deviation, or
drift correction, or incorrect measurement
of course on the chart will be graded as un-
satisfactory.
(12) Demonstrate or explain the use of
characteristics of various chart projections
used in long-range air navigation, including
the plotting of courses and bearings, and the
measuring of distances.
(13) Demonstrate ability to identify des-
ignated landmarks by the use of a sectional
or WAC chart.
(14) Use a computer with facility and accu-
racy for the computation of winds, drift cor-
rection and drift angles, ground speeds,
ETA’s, fuel loads, etc.
(15) Determine track, ground speed, and
wind by the double drift method. When a
drift meter is not part of the aircraft’s equip-
ment, an oral examination on the use of the
drift meter and a double drift problem shall
be completed.
(16) Determine ground speed and wind by
the timing method with a drift meter. When
a drift meter is not part of the aircraft’s
equipment, an oral examination on the pro-
cedure and a problem shall be completed.
(17) Demonstrate the use of air plot for de-
termining wind between fixes and for plot-
ting pressure lines of position when using
pressure and absolute altimeter compari-
sons.
(18) Give ETA’s to well defined check
points at least once each hour after the sec-
ond hour of flight. The average error shall
