Navigation Aids

(l) GPS Familiarization

Pilots should practice GPS approaches in visual
meteorological conditions (VMC) until thoroughly
proficient with all aspects of their equipment
(receiver and installation) prior to attempting flight
in instrument meteorological conditions (IMC).
Pilots should be proficient in the following areas:

(1)

Using the receiver autonomous integ-

rity monitoring (RAIM) prediction function;

(2)

Inserting a DP into the flight plan,

including setting terminal CDI sensitivity, if required,
and the conditions under which terminal RAIM is
available for departure;

(3)

Programming the destination airport;

(4)

Programming and flying the ap-

proaches (especially procedure turns and arcs);

(5)

Changing to another approach after

selecting an approach;

(6)

Programming and flying “direct”

missed approaches;

(7)

Programming and flying “routed”

missed approaches;

(8)

Entering, flying, and exiting holding

patterns, particularly on approaches with a second
waypoint in the holding pattern;

(9)

Programming and flying a “route” from

a holding pattern;

(10)

Programming and flying an approach

with radar vectors to the intermediate segment;

(11)

Indication of the actions required for

RAIM failure both before and after the FAWP; and

(12)

Programming a radial and distance

from a VOR (often used in departure instructions).
