14 CFR Ch. I (1–1–19 Edition)
§ 29.75
of category A, the steady angle of glide
must be determined in autorotation—
(a) At the forward speed for min-
imum rate of descent as selected by the
applicant;
(b) At the forward speed for best glide
angle;
(c) At maximum weight; and
(d) At the rotor speed or speeds se-
lected by the applicant.

§ 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.

§ 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
