C.3 Conducting the GMU 11 Location Survey
This section describes the setup and procedure required to successfully complete the GMU 11 location
survey using the G5.
C.3.1 Aircraft and GMU 11 Setup
Prepare the aircraft and GMU 11 for the location survey by completing the following steps:
1.
Prepare a detailed survey sequence list with start and stop times for exercising all aircraft
components and devices that may affect the operation of the GMU 11 magnetometer through
movement of ferrous metal parts or electrical inductance. Aircraft components included on the list
will vary depending on aircraft model. An example survey sequence is provided below.
2.
Position the aircraft in a magnetically quiet area. This step may involve repositioning large metal
objects including aircraft and ground support equipment away from the survey area.
3.
Position the GMU 11 in the aircraft location to be surveyed.
