14 CFR Ch. I (1–1–19 Edition) 

§ 29.773 

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.

§ 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.

§ 29.775

Windshields and windows. 

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
