the controller will advise that the aircraft is approaching the glide path. When the
aircraft reaches the point where final descent is to start, the controller will state
"begin descent." At that point, establish the predetermined rate of descent.
Adjust power or use drag devices as required to maintain desired airspeed or
angle of attack. When the airspeed or angle of attack and glide path are stabilized
note the power, attitude, and vertical velocity. Use these values as guides during
the remainder of the approach.
14.3.5.2.3. Controller Guidance. The controller issues course and glide path
guidance, and frequently informs you of any deviation from course or glide path.
The controller's terminology will be: on course; on glide path; slightly/well
above/below glide path; or slightly/well left/right of course. Controllers may also
issue trend information to assist you in conducting a PAR approach. Examples of
trend information phraseologies that may be used are: going above/below glide
path, holding above/below glide path, holding left/right or course, etc. Trend
information may be modified by the use of the terms rapidly or slowly as
appropriate. The terms "slightly" or "well" are used in conjunction with the trend
information.
14.3.5.2.4. Corrections. Corrections should be made immediately after
instructions are given or when deviation from established attitude or desired
performance is noted. Avoid excessive throttle, pitch, or bank changes. Normally
pitch changes of one degree will be sufficient to correct back to glide path.
14.3.5.2.5. Heading Control. Accurate heading control is important for runway
alignment during the final approach phase. When instructed to make heading
changes, make them immediately. Heading instructions are preceded by the
phrase "turn right" or "turn left." To prevent overshooting, the angle of bank
should approximate the number of degrees to be turned, not to exceed a one-half
standard rate turn. At high final approach speeds, a large angle of bank may be
required to prevent a prolonged correction. In any case, do not exceed the onehalf
standard rate turn. After a new heading is directed, the controller assumes it
is being maintained. Additional heading corrections will be based on the last
assigned heading.
14.3.5.2.6. Decision Height (DH). DH is the height at which a decision must be
made during a precision approach to either continue the approach or to execute a
missed approach. Continued descent below DH is not authorized until sufficient
visual reference with the runway environment has been established. A
momentary deviation below DH without the runway environment in sight is
only authorized in conjunction with a proper missed approach initiated at DH.
Definition of runway environment is found in paragraph 14.2.1.2.6. The
controller will advise the pilot when the aircraft reaches the published DH. DH is
determined in the cockpit either as read on the altimeter or when advised by the
controller, whichever occurs first. The controller will continue to provide
advisory course and glide path information until the aircraft passes over the
landing threshold at which time the controller will advise "over landing
threshold." To provide a smooth transition from instrument to visual conditions, a
systematic scan for runway environment should be integrated into the crosscheck
