The visual system must provide at least a
field-of-view of 18
°
vertical/24
°
horizontal
for the pilot flying.
An SOC is required .........................................

6.a.4. .........
The visual system must provide for a max-
imum parallax of 10
°
per pilot.
An SOC is required .........................................

The visual scene content may not be dis-
tracting.

6.a.6. .........
The minimum distance from the pilot’s eye
position to the surface of a direct view dis-
play may not be less than the distance to
any front panel instrument.

6.a.7. .........
The visual system must provide for a min-
imum resolution of 5 arc-minutes for both
computed and displayed pixel size.
An SOC is required .........................................

6.b. ............
If a visual system is installed and additional
training, testing, or checking credits are
being sought on the basis of having a vis-
ual system, a visual system meeting the
standards set out for at least a Level A FFS
(see Appendix A of this part) will be re-
quired. A ‘‘direct-view,’’ non-collimated vis-
ual system (with the other requirements for
a Level A visual system met) may be con-
sidered satisfactory for those installations
where the visual system design ‘‘eye point’’
is appropriately adjusted for each pilot’s po-
sition such that the parallax error is at or
less than 10
°
simultaneously for each pilot.
An SOC is required .........................................

6.c. ............
The FTD must provide a continuous visual
field-of-view of at least 146
°
horizontally
and 36
°
vertically for both pilot seats, simul-
taneously. The minimum horizontal field-of-
view coverage must be plus and minus
one-half (
1
⁄
2
) of the minimum continuous
field-of-view requirement, centered on the
zero degree azimuth line relative to the air-
craft fuselage. Additional horizontal field-of-
view capability may be added at the spon-
sor’s discretion provided the minimum field-
of-view is retained. Capability for a field-of-
view in excess of these minima is not re-
quired for qualification at Level 7. However,
where specific tasks require extended fields
of view beyond the 146
°
by 36
°
(e.g., to ac-
commodate the use of ‘‘chin windows’’
where the accommodation is either integral
with or separate from the primary visual
system display), then such extended fields
of view must be provided.
An SOC is required and must explain the ge-
ometry of the installation.
X Optimization of the vertical field-of-view may
be considered with respect to the specific
helicopter flight deck cut-off angle. When
considering the installation/use of aug-
mented fields of view, as described here, it
will be the responsibility of the sponsor to
meet with the NSPM to determine the train-
ing, testing, checking, or experience tasks
for which the augmented field-of-view capa-
bility may be critical to that approval.
