C. Orientation
(1) Mount the C406-1HM ELT parallel to the waterline of the fuselage, along the longitudinal axis,
with the direction-of-flight arrow on the ELT pointing forward. See "Figure 27. Orientation of
ELT for Helicopter Installations".
NOTE: This is the orientation of the primary G-switch in the ELT.
(2) The ELT may be angled downward as much as 25°, if necessary.
NOTE: Keep in mind, the steeper the mounting angle, the more pre-load on the primary G-
switch and the increased likelihood of “nuisance” activations.
(3) All other installation requirements contained herein are applicable and must be adhered to.
