14 CFR Ch. I (1–1–19 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
