14 CFR Ch. I (1–1–14 Edition)
§ 97.3
(1) Initial approach is the segment
between the initial approach fix and
the intermediate fix or the point where
the aircraft is established on the inter-
mediate course or final approach
course.
(2) Initial approach altitude is the al-
titude (or altitudes, in high altitude
procedure) prescribed for the initial ap-
proach segment of an instrument ap-
proach.
(3) Intermediate approach is the seg-
ment between the intermediate fix or
point and the final approach fix.
(4) Final approach is the segment be-
tween the final approach fix or point
and the runway, airport, or missed ap-
proach point.
(5) Missed approach is the segment
between the missed approach point, or
point of arrival at decision altitude or
decision height (DA/DH), and the
missed approach fix at the prescribed
altitude.
Ceiling means the minimum ceiling,
expressed in feet above the airport ele-
vation, required for takeoff or required
for designating an airport as an alter-
nate airport.
Copter procedures means helicopter
procedures, with applicable minimums
as prescribed in § 97.35. Helicopters may
also use other procedures prescribed in
subpart C of this part and may use the
Category A minimum descent altitude
(MDA), or decision altitude or decision
height (DA/DH). For other than
‘‘copter-only’’ approaches, the required
visibility minimum for Category I ap-
proaches may be reduced to one-half
the published visibility minimum for
Category A aircraft, but in no case
may it be reduced to less than one-
quarter mile prevailing visibility, or, if
reported, 1,200 feet RVR. Reduction of
visibility minima on Category II in-
strument approach procedures is pro-
hibited.
FAF means final approach fix.
HAA means height above airport and
is expressed in feet.
HAL means height above landing and
is the height of the DA/MDA above a
designated helicopter landing area ele-
vation used for helicopter instrument
approach procedures and is expressed
in feet.
HAS means height above the surface
and is the height of the DA/MDA above
the highest terrain/surface within a
5,200-foot radius of the missed approach
point used in helicopter instrument ap-
proach procedures and is expressed in
feet above ground level (AGL).
HAT means height above touchdown.
HCH means helipoint crossing height
and is the computed height of the
vertical guidance path above the
helipoint elevation at the helipoint ex-
pressed in feet.
Helipoint means the aiming point for
the final approach course. It is nor-
mally the center point of the touch-
down and lift-off area (TLOF).
Hold in lieu of PT means a holding
pattern established under applicable
FAA criteria, and used in lieu of a pro-
cedure turn to execute a course rever-
sal.
MAP means missed approach point.
More than 65 knots means an aircraft
that has a stalling speed of more than
65 knots (as established in an approved
flight manual) at maximum certifi-
cated landing weight with full flaps,
landing gear extended, and power off.
MSA means minimum safe altitude,
expressed in feet above mean sea level,
depicted on an approach chart that
provides at least 1,000 feet of obstacle
clearance for emergency use within a
certain distance from the specified
navigation facility or fix.
NA means not authorized.
NOPT means no procedure turn re-
quired. Altitude prescribed applies only
if procedure turn is not executed.
Procedure turn means the maneuver
prescribed when it is necessary to re-
verse direction to establish the aircraft
on an intermediate or final approach
course. The outbound course, direction
of turn, distance within which the turn
must be completed, and minimum alti-
tude are specified in the procedure.
However, the point at which the turn
may be begun, and the type and rate of
turn, is left to the discretion of the
pilot.
RA means radio altimeter setting
height.
RVV means runway visibility value.
SIAP means standard instrument ap-
proach procedure.
65 knots or less means an aircraft that
has a stalling speed of 65 knots or less
(as established in an approved flight
