§ 29.783
pilot position. Flight and powerplant
controls must be designed to prevent
confusion or inadvertent operation
when the rotorcraft is piloted from ei-
ther position;
(c) The vibration and noise charac-
teristics of cockpit appurtenances may
not interfere with safe operation;
(d) Inflight leakage of rain or snow
that could distract the crew or harm
the structure must be prevented.

amended by Amdt. 29–3, 33 FR 967, Jan. 26,

§ 29.773
Pilot compartment view.
(a)
Nonprecipitation conditions. For
nonprecipitation conditions, the fol-
lowing apply:
(1) Each pilot compartment must be
arranged to give the pilots a suffi-
ciently extensive, clear, and undis-
torted view for safe operation.
(2) Each pilot compartment must be
free of glare and reflection that could
interfere with the pilot’s view. If cer-
tification for night operation is re-
quested, this must be shown by night
flight tests.
(b)
Precipitation conditions. For pre-
cipitation conditions, the following
apply:
(1) Each pilot must have a suffi-
ciently extensive view for safe oper-
ation—
(i) In heavy rain at forward speeds up
to
V
H
; and
(ii) In the most severe icing condi-
tion for which certification is re-
quested.
(2) The first pilot must have a win-
dow that—
(i) Is openable under the conditions
prescribed in paragraph (b)(1) of this
section; and
(ii) Provides the view prescribed in
that paragraph.

Windshields and windows must be
made of material that will not break
into dangerous fragments.

§ 29.777
Cockpit controls.
Cockpit controls must be—
(a) Located to provide convenient op-
eration and to prevent confusion and
inadvertent operation; and
(b) Located and arranged with re-
spect to the pilot’s seats so that there
is full and unrestricted movement of
each control without interference from
the cockpit structure or the pilot’s
clothing when pilots from 5

to 6

height are seated.
§ 29.779
Motion and effect of cockpit
controls.
Cockpit controls must be designed so
that they operate in accordance with
the following movements and actu-
ation:
(a) Flight controls, including the col-
lective pitch control, must operate
with a sense of motion which cor-
responds to the effect on the rotor-
craft.
(b) Twist-grip engine power controls
must be designed so that, for lefthand
operation, the motion of the pilot’s
hand is clockwise to increase power
when the hand is viewed from the edge
containing the index finger. Other en-
gine power controls, excluding the col-
lective control, must operate with a
forward motion to increase power.
(c) Normal landing gear controls
must operate downward to extend the
landing gear.
[Amdt. 29–24, 49 FR 44437, Nov. 6, 1984]
§ 29.783
Doors.
(a) Each closed cabin must have at
least one adequate and easily acces-
sible external door.
(b) Each external door must be lo-
cated, and appropriate operating proce-
dures must be established, to ensure
that persons using the door will not be
endangered by the rotors, propellers,
engine intakes, and exhausts when the
operating procedures are used.
(c) There must be means for locking
crew and external passenger doors and
for preventing their opening in flight
inadvertently or as a result of mechan-
ical failure. It must be possible to open
external doors from inside and outside
the cabin with the rotorcraft on the
ground even though persons may be
crowded against the door on the inside
