§ 29.85 

§ 29.75

Landing: General. 

(a) For each rotorcraft— 
(1) The corrected landing data must 

be determined for a smooth, dry, hard, 
and level surface; 

(2) The approach and landing must 

not require exceptional piloting skill 
or exceptionally favorable conditions; 
and 

(3) The landing must be made with-

out excessive vertical acceleration or 
tendency to bounce, nose over, ground 
loop, porpoise, or water loop. 

(b) The landing data required by 

§§ 29.77, 29.79, 29.81, 29.83, and 29.85 must 
be determined— 

(1) At each weight, altitude, and tem-

perature for which landing data are ap-
proved; 

(2) With each operating engine within 

approved operating limitations; and 

(3) With the most unfavorable center 

of gravity. 

[Doc. No. 24802, 61 FR 21900, May 10, 1996] 

§ 29.77

Landing Decision Point (LDP): 

Category A. 

(a) The LDP is the last point in the 

approach and landing path from which 
a balked landing can be accomplished 
in accordance with § 29.85. 

(b) Determination of the LDP must 

include the pilot recognition time in-
terval following failure of the critical 
engine. 

[Doc. No. 24802, 64 FR 45338, Aug. 19, 1999] 

§ 29.79

Landing: Category A. 

(a) For Category A rotorcraft— 
(1) The landing performance must be 

determined and scheduled so that if the 
critical engine fails at any point in the 
approach path, the rotorcraft can ei-
ther land and stop safely or climb out 
and attain a rotorcraft configuration 
and speed allowing compliance with 
the climb requirement of § 29.67(a)(2); 

(2) The approach and landing paths 

must be established with the critical 
engine inoperative so that the transi-
tion between each stage can be made 
smoothly and safely; 

(3) The approach and landing speeds 

must be selected by the applicant and 
must be appropriate to the type of 
rotorcraft; and 

(4) The approach and landing path 

must be established to avoid the crit-

ical areas of the height-velocity enve-
lope determined in accordance with 
§ 29.87. 

(b) It must be possible to make a safe 

landing on a prepared landing surface 
after complete power failure occurring 
during normal cruise. 

[Doc. No. 24802, 61 FR 21900, May 10, 1996] 

§ 29.81

Landing distance: Category A. 

The horizontal distance required to 

land and come to a complete stop (or to 
a speed of approximately 3 knots for 
water landings) from a point 50 ft 
above the landing surface must be de-
termined from the approach and land-
ing paths established in accordance 
with § 29.79. 

[Doc. No. 24802, 64 FR 45338, Aug. 19, 1999] 

§ 29.83

Landing: Category B. 

(a) For each Category B rotorcraft, 

the horizontal distance required to 
land and come to a complete stop (or to 
a speed of approximately 3 knots for 
water landings) from a point 50 feet 
above the landing surface must be de-
termined with— 

(1) Speeds appropriate to the type of 

rotorcraft and chosen by the applicant 
to avoid the critical areas of the 
height-velocity envelope established 
under § 29.87; and 

(2) The approach and landing made 

with power on and within approved 
limits. 

(b) Each multiengined Category B 

rotorcraft that meets the powerplant 
installation requirements for Category 
A must meet the requirements of— 

(1) Sections 29.79 and 29.81; or 
(2) Paragraph (a) of this section. 
(c) It must be possible to make a safe 

landing on a prepared landing surface if 
complete power failure occurs during 
normal cruise. 

[Doc. No. 24802, 61 FR 21900, May 10, 1996; 61 
FR 33963, July 1, 1996] 

§ 29.85

Balked landing: Category A. 

For Category A rotorcraft, the 

balked landing path with the critical 
engine inoperative must be established 
so that— 

(a) The transition from each stage of 

the maneuver to the next stage can be 
made smoothly and safely;
