C. Orientation
(1) Mount the ME406HM ELT parallel to the waterline of the fuselage, along the longitudinal axis,
with the direction-of-flight arrow on the ELT pointing forward.
NOTE
: This is the orientation of the primary G-switch in the ELT.
(2) The ELT may be oriented on any of its horizontal axes in 90° increments.
NOTE
: Ensure that the front of the ELT is aligned with the nose of the aircraft with no more
than 5° deflection in any direction to ensure proper operation of the 6-axis G-Switch
sensors.
(3) All other installation requirements contained herein are applicable and must be adhered to.
