aircraft position. Then visualize the new radial to intercept as is done in point-to-point scenarios.
(Course to Bearing + 30° = intercept heading; memory aid, inbound: Charlie Brown + 30°)
Turn. Turn in the shorter direction to the intercept heading.
Maintain. Maintain the intercept heading until a lead point is reached, then complete the intercept.
Outbound-Away from the Station (HSI).
Tune and identify the station.
Set. Set the desired outbound course in the course selector window.
Turn. Turn in the shorter direction toward the CDI until the head of the course arrow is in the top
half of the instrument case. This precludes an intercept angle in excess of 90°. Roll out of the turn
on an intercept heading with a suitable angle of intercept, normally 45°. A 45° intercept angle is
established by rolling out with the head of the course arrow under the appropriate 45 ° index (aircraft
symbol directed toward the CDI).
Maintain. Maintain the intercept heading until a lead point is reached, then complete the intercept.
Outbound-Away From the Station (RMI Only).
Tune and identify the station.
Determine an intercept heading. Look from the tail of the bearing pointer past the desired course
and select an intercept heading. Any heading beyond the desired course, within 90°, is a no-wind
intercept heading. A heading selected 45° beyond the desired course will normally ensure a
moderate rate of intercept. As an aid, visualize the problem utilizing the RMI center as the station
and the tail of the bearing pointer as the present aircraft position. Then visualize the new radial to
intercept as is done in point-to-point scenarios.
(Tail to Course + 45° = intercept heading; memory aid, outbound: Tom Collins + 45°)
Turn. Turn in the shorter direction to the intercept heading.
Maintain. Maintain the intercept heading until a lead point is reached, then complete the intercept.
Outbound -- Immediately After Station Passage (HSI).
Tune and identify the station. This should have already been accomplished.
Turn. Turn in the shorter direction to a heading that will parallel or intercept the outbound course.
Turning to parallel the desired outbound course is always acceptable. Continuing the turn to an
intercept heading may be preferable when the bearing pointer is stabilized or when you know your
position in relation to the desired course. The effect airspeed, wind, and magnitude of turn will have
on aircraft position during the turn to an intercept heading should be considered.
Set course. Set the desired course in the course selector window and check for FROM indication.
Turn to Intercept. Turn to an intercept heading if not previously accomplished. Determine the
number of degrees off course as indicated by CDI displacement or angular difference between the
tail of the bearing pointer and the desired course. If the initial turn was to parallel the desired course,
turn toward the CDI to establish an intercept angle approximately equal to the number of degrees off
course. Normally, to avoid overshooting, an intercept angle greater than 45° should not be used.
Maintain. Maintain the intercept heading until a lead point is reached, then complete the intercept.
Outbound -- Immediately After Station Passage (RMI Only).
Tune and identify the station. This should have already been accomplished.
Turn. Turn in the shorter direction to a heading that will parallel or intercept the outbound course.
Degrees Off Course. Determine the number of degrees off course. Note the angular difference
between the tail of the bearing pointer and the desired course.
