Pt. 60, App. D
The visible segment in the simu-
lator must be within 20% of the
segment computed to be visible
from the helicopter flight deck.
The tolerance(s) may be ap-
plied at either end or at both
ends of the displayed segment.
However, lights and ground ob-
jects computed to be visible
from the helicopter flight deck
at the near end of the visible
segment must be visible in the
simulator.
Landing configura-
tion, trimmed for
appropriate air-
speed, at 100 ft
(30m) above the
touchdown zone,
on glide slope with
an RVR value set
at 1,200 ft (350m).
The QTG must contain relevant
calculations and a drawing
showing the data used to es-
tablish the helicopter location
and the segment of the ground
that is visible considering de-
sign eyepoint, helicopter atti-
tude, flight deck cut-off angle,
and a visibility of 1200 ft (350
m) RVR. Simulator perform-
ance must be measured
against the QTG calculations.
The data submitted must in-
clude at least the following: (1)
Static helicopter dimensions as
follows: (i) Horizontal and
vertical distance from main
landing gear (MLG) to
glideslope reception antenna.
(ii) Horizontal and vertical dis-
tance from MLG to pilot’s
eyepoint. (iii) Static flight deck
cutoff angle. (2) Approach data
as follows: (i) Identification of
runway. (ii) Horizontal distance
from runway threshold to
glideslope intercept with run-
way. (iii) Glideslope angle. (iv)
Helicopter pitch angle on ap-
proach. (3) Helicopter data for
manual testing: (i) Gross
weight. (ii) Helicopter configura-
tion. (iii) Approach airspeed. If
non-homogenous fog is used to
obscure visibility, the vertical
variation in horizontal visibility
must be described and be in-
cluded in the slant range visi-
bility calculation used in the
computations.

Pre-position for this test is
encouraged, but may be
achieved via manual or
autopilot control to the
desired position.
