33.4.19.3.2 Engine/Airframe Input Configuration Items

This section briefly describes how to configure the engine/airframe inputs for each supported sensor type,

using the Engine Configuration page. Where applicable, differences between the GEA 24 and GSU 73 are

noted. Refer to

CHT (Cylinder Head Temperature)

Thermocouples: Up to six thermocouples can be connected to the CHT thermocouple inputs on the GEA

24 or GSU 73. Both J-type and K-type thermocouples are supported. Select 1, 2, 4, or 6 cylinders of CHT

thermocouple monitoring.

Rotax CHT sensors: Rotax CHT sensor part numbers 965531 and 966385 are supported. For the GEA 24,

Rotax CHT sensors are configured using the same CHT input page but are connected to different GEA 24

31.2). For the GSU 73, Rotax CHT sensors are connected and configured using the

GSU 73 general purpose (GP) inputs

Thermocouples: Up to six Type-K thermocouples can be connected to the EGT thermocouple inputs on the

GEA 24 or GSU 73. Select 1, 2, 4, or 6 cylinders of EGT thermocouple monitoring. If Lean Assist using

EGT is desired, change the Lean Assist setting to "Enabled". (see

Rotax 912iS/915iS: For the GEA 24, select "Rotax FADEC" as the EGT configuration to use EGT data

from the Rotax 912iS/915iS FADEC interface.

The EGT 6/MISC PRESS input on the GSU 73 has multiple functions. If the GSU 73

EGT 6/MISC PRESS input has been configured for a sensor that is not an EGT

thermocouple, only four EGT thermocouples can be configured.

One or two Type K thermocouples can be connected for turbine inlet temperature monitoring, using the

TIT 1 and TIT 2 inputs on the GEA 24 or GSU 73. If Lean Assist using TIT is desired, change the Lean

Assist setting to "Enabled". (see
