Phraseology: HEADING (heading), ON COURSE,
SLIGHTLY (or WELL) (LEFT or RIGHT) OF COURSE.
(2) Issue trend information, as required, to show target position
with respect to the extended runway centerline and to describe the target
movement as you give proper corrections.
You may change trend
information by the terms rapidly or slowly, as proper.
Phraseology: SLIGHTLY (or WELL) (LEFT or RIGHT) OF COURSE,
CORRECTING (SLOWLY or RAPIDLY).
(3) Inform the aviator of the aircraft's distance from the runway,
airport, heliport, or missed-approach point (MAP), as proper, each mile
Phraseology: (Number) MILES FROM (RUNWAY, AIRPORT, HELIPORT, or
(4) Furnish recommended altitudes only when the aviator requests
Phraseology: ALTITUDE SHOULD BE (altitude).
NOTE: Give the distance and altitude together each mile before the
aircraft reaches the MDA.
p. Recommended Altitudes
(1) For a straight-in approach to the runway, use a 300-foot slope
for each mile from the runway touchdown zone (TDZ).
EXAMPLE: If the elevation at the TDZ is 200 feet above mean sea level
(MSL), add 300 feet to get the 1-mile recommended altitude of 500 feet
MSL. At 2 miles, the recommended altitude would be 800 feet MSL (200 +
600); at 3 miles, 1,100 feet MSL (200 + 900); and so on.
(2) For a circling approach, apply the same
compute airport elevation instead of TDZ elevation.
EXAMPLE: If the airport elevation is 300 feet MSL, add 300 feet. The
recommended altitude at 1 mile is 600 feet MSL; at 2 miles, 900 feet MSL;
and so on.
