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.

X  Pre-position for this test is 

encouraged, but may be 
achieved via manual or 
autopilot control to the 
desired position.
