1.1.4 Remote Sensor Module (RSM)
The Remote Sensor Module (RSM) (Figure 1-9), is an integral part of the EFD1000
system and works together with the display unit sensors as part of the AHRS and ADC.
The RSM looks and mounts like a GPS antenna and is mounted on the exterior of the
fuselage, typically aft of the cabin.
The RSM contains the following sub-systems:
• 3D magnetic flux (heading) sensors
• Outside Air Temperature (OAT) sensor
• Emergency backup GPS engine and antenna
The RSM communicates with the PFD via a digital cable connection.
