Appendix A to Part 63 - Test Requirements for Flight Navigator
Certificate
(a) Demonstration of skill. An applicant will be required
to pass practical tests on the prescribed subjects. These tests may
be given by FAA inspectors and designated flight navigator
examiners.
(b) The examination. The practical examination consists
of a ground test and a flight test as itemized on the examination
check sheet. Each item must be completed satisfactorily in order
for the applicant to obtain a passing grade. Items 5, 6, 7 of the
ground test may be completed orally, and items 17, 22, 23, 34, 36,
37, 38, and 39 of the flight test may be completed by an oral
examination when a lack of ground facilities or navigation
equipment makes such procedure necessary. In these cases a notation
to that effect shall be made in the “Remarks” space on the check
sheet.
(c) Examination procedure. (1) An applicant will provide
an aircraft in which celestial observations can be taken in all
directions. Minimum equipment shall include a table for plotting, a
drift meter or absolute altimeter, an instrument for taking visual
bearings, and a radio direction finder.
(2) More than one flight may be used to complete the flight test
and any type of flight pattern may be used. The test will be
conducted chiefly over water whenever practicable, and without
regard to radio range legs or radials. If the test is conducted
chiefly over land, a chart should be used which shows very little
or no topographical and aeronautical data. The total flight time
will cover a period of at least four hours. Only one applicant may
be examined at one time, and no applicant may perform other than
navigator duties during the examination.
(3) When the test is conducted with an aircraft belonging to an
air carrier, the navigation procedures should conform with those
set forth in the carrier's operations manual. Items of the flight
test which are not performed 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
aircraft will have considerable effect on an applicant's
performance, good judgment must be used by the agent or examiner in
evaluating the tests.
(d) Ground test. For the ground test, in the order of the
numbered items on the examination check sheet, an applicant will be
required 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
identification.
(2) Identify two additional stars with a star identifier or sky
diagrams and explain identification 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 rising 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
position of the observer.
(5) Demonstrate or explain the compensation 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 sextant.
(e) Flight test. For the flight test, in the order of the
numbered items on the examination check sheet, an applicant will be
required to:
(1) Demonstrate his ability to read weather symbols and
interpret synoptic surface and upper air weather maps with
particular emphasis 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 variations of the actual curve from the predicted
curve.
(7) Check the presence on board and operating condition of all
navigation equipment. Normally a check list will be used. This
check will include a time tick or chronometer 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 stations during
emergencies for the type of aircraft used for the test.
(10) Demonstrate the proper use of a flux gate compass or
gyrosyn compass (when available), with special emphasis on the
caging methods and the location of switches, circuit breakers, and
fuses. If these compasses are not part of the aircraft's equipment,
an oral examination will be given.
(11) Be accurate and use good judgment when setting and altering
headings. Erroneous application of variation, deviation, or drift
correction, or incorrect measurement of course on the chart will be
graded as unsatisfactory.
(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 designated landmarks by the
use of a sectional or WAC chart.
(14) Use a computer with facility and accuracy for the
computation of winds, drift correction 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 equipment,
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 procedure and a problem shall
be completed.
(17) Demonstrate the use of air plot for determining wind
between fixes and for plotting pressure lines of position when
using pressure and absolute altimeter comparisons.
(18) Give ETA's to well defined check points at least once each
hour after the second hour of flight. The average error shall not
be more than 5 percent of the intervening time intervals, and the
maximum error of any one ETA shall not be more than 10 percent.
(19) Demonstrate knowledge and use of D/F equipment and radio
facility information. Grading on this item will be based largely on
the applicant's selection of those radio aids which will be of most
value to his navigation, the manner with which he uses equipment,
including filter box controls, and the precision with which he
reads bearings. The aircraft's compass heading and all compass
corrections must be considered for each bearing.
(20) Use care in tuning to radio stations to insure maximum
reception of signal and check for interference signals. Receiver
will be checked to ascertain that antenna and BFO (Voice-CW)
switches are in correct positions.
(21) Identify at least three radio stations using International
Morse code only for identification. The agent or examiner will tune
in these stations so that the applicant will have no knowledge of
the direction, distance, or frequency of the stations.
(22) Take at least one radio bearing by manual use of the loop.
The agent or examiner will check the applicant's bearing by taking
a manual bearing on the same station immediately after the
applicant.
(23) Show the use of good judgment in evaluating radio bearings,
and explain why certain bearings may be of doubtful value.
(24) Determine and apply correctly the correction required to be
made to radio bearings before plotting them on a Mercator chart,
and demonstrate the ability to plot bearings accurately on charts
of the Mercator and Lambert conformal projections.
(25) Compute the compass heading, ETA, and fuel remaining if it
is assumed that the flight would be diverted to an alternate
airport at a time specified by the agent or examiner.
(26)-(28) [Reserved]
(29) Demonstrate the ability to properly operate and read an
absolute altimeter.
(30) Determine the “D” factors for a series of compared readings
of an absolute altimeter and a pressure altimeter.
(31) Determine drift angle or lateral displacement from the true
headingline by application of Bellamy's formula or a variation
thereof.
(32) Interpret the altimeter comparison data with respect to the
pressure system found at flight level. From this data evaluate the
accuracy of the prognostic weather map used for flight planning and
apply this analysis to the navigation of the flight.
(33) Interpret single LOP's for most probable position, and show
how a series of single LOP's of the same body may be used to
indicate the probable track and ground speed. Also, show how a
series of single LOP's (celestial or radio) from the same celestial
body or radio station may be used to determine position when the
change of azimuth or bearing is 30° or more between
observations.
(34) Select one of the celestial LOP's used during the flight
and explain how to make a single line of position approach to a
point selected by the agent or examiner, giving headings, times,
and ETA's.
(35) Demonstrate the proper use of an astro-compass or
periscopic sextant for taking bearings.
(36) Determine compass deviation as soon as possible after
reaching cruising altitude and whenever there is a change of
compass heading of 15° or more.
(37) Take celestial fixes at hourly intervals when conditions
permit. The accuracy of these fixes shall be checked by means of a
radio or visual fix whenever practicable. After allowing for the
probable error of a radio or visual fix, a celestial fix under
favorable conditions should plot within 10 miles of the actual
position.
(38) Select celestial bodies for observation, when possible,
whose azimuths will differ by approximately 120° for a 3-body fix
and will differ by approximately 90° for a 2-body fix. The
altitudes of the selected bodies should be between 25° and 75°
whenever practicable.
(39) Have POMAR and any other required reports ready for
transmission at time of schedule, and be able to inform the pilot
in command promptly with regard to the aircraft's position and
progress in comparison with the flight plan.
(40) Keep a log with sufficient legible entries to provide a
record from which the flight could be retraced.
(41) Note significant weather changes which might influence the
drift or ground speed of the aircraft, such as, temperature, “D”
factors, frontal conditions, turbulence, etc.
(42) Determine the wind between fixes as a regular practice.
(43) Estimate the time required and average ground speed during
a letdown, under conditions specified by the pilot in command.
(44) Work with sufficient speed to determine the aircraft's
position hourly by celestial means and also make all other
observations and records pertinent to the navigation. The applicant
should be able to take the observation, compute, and plot a
celestial LOP within a time limit of 8 minutes; observe the
absolute and pressure altimeters and compute the drift or lateral
displacement within a time limit of 3 minutes.
(45) Be accurate in reading instruments and making computations.
Errors which are made and corrected without affecting the
navigation will be disregarded unless they cause considerable loss
of time.
An uncorrected error in computation (including reading
instruments and books) which will affect the reported position more
than 25 miles, the heading more than 3°, or any ETA more than 15
minutes will cause this item to be graded unsatisfactory.
(46) Be alert to changing weather or other conditions during
flight which might affect the navigation. An applicant should not
fail to take celestial observations just prior to encountering a
broken or overcast sky condition; and he should not fail to take a
bearing on a radio station, which operates at scheduled intervals
and which would be a valuable aid to the navigation.
(47) Show a logical choice and sequence in using the various
navigation methods according to time and accuracy, and check the
positions determined by one method against positions determined by
other methods.
(48) Use a logical sequence in performing the various duties of
a navigator and plan work according to a schedule. The more
important duties should not be neglected for others of less
importance.
