§ 29.779
§ 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 ground
or 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.
(c)
Vision systems with transparent dis-
plays. A vision system with a trans-
parent display surface located in the
pilot’s outside field of view, such as a
head up-display, head mounted display,
or other equivalent display, must meet
the following requirements in non-
precipitation and precipitation condi-
tions:
(1) While the vision system display is
in operation, it must compensate for
interference with the pilot’s outside
field of view such that the combination
of what is visible in the display and
what remains visible through and
around it, allows the pilot compart-
ment to satisfy the requirements of
paragraphs (a) and (b) of this section.
(2) The pilot’s view of the external
scene may not be distorted by the
transparent display surface or by the
vision system imagery. When the vi-
sion system displays imagery or any
symbology that is referenced to the im-
agery and outside scene topography,
including attitude symbology, flight
path vector, and flight path angle ref-
erence cue, that imagery and sym-
bology must be aligned with, and
scaled to, the external scene.
(3) The vision system must provide a
means to allow the pilot using the dis-
play to immediately deactivate and re-
activate the vision system imagery, on
demand, without removing the pilot’s
hands from the primary flight and
power controls, or their equivalent.
(4) When the vision system is not in
operation it must permit the pilot
compartment to satisfy the require-
ments of paragraphs (a) and (b) of this
section.

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

in
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
