5.6.3 Types of Throttle Curves 

FULL EXPO:  Means linear RPM, it is the default setting and the mode used for all previous software 

versions. Thrust develops exponentially, and it is the recommended curve for big engines 
and/or high thrust/weight ratio planes, as it eases the control in low power used during taxi. 

LINEAR:  

Means that the thrust develops linearly with the throttle settings. It could cause difficult taxi, 
as it would be difficult to fine adjust the power at low settings. 

HALF EXPO:  An intermediate setting between the other two modes.

5.7 Info Menu 

The info menu is used to display the Total Time, Service Time, Turbine Serial Number, and the Software 
Version of the Power/Pack ECU. 

“TOTAL TIME” is the running time since turbine fabrication 

“SERVICE TIME” ” is the running time since last service; this time is reset to 
zero whenever the Turbine is returned to the authorized Jet Central service 
facility for the 25 hour service procedure.
