Note:
Some Broncos were changed to always read EGT on the EGT/TIT
gauge. This option is available on the Aerosoft OV-10 Bronco too
through the Checklist/Config gauge .
When set to EGT readout only, the pilot is required to determine max
allowable EGT with the help of EGT charts.
The TIT warn lights are hardcoded to 996°C and will not warn for any
EGT over temperature situation since EGT is much lower than TIT.
TIT is not a measured value, since no temperature probe type is able to
withstand the temperatures at the turbine inlet. Instead TIT is calcula-
ted and “tweaked” by the SRL computer to read a TIT value giving a
single red-line value- i.e EGT is converted to TIT and this value is again
compensated for Ng, OAT, Altitude and Airspeed in order to make the
gauge needle read 996°C when reaching max allowable TIT, which
again will lit the TIT warn light.
