|As a small diversion for a couple of hours we did some calibration testing on the FADEC sensors - the CHT / EGT probes provide the engine with key data and that is then passed onto the GRT EIS / avionics. |
Using a meat thermometer and a ball of warm / boiling water we tested the probes. I wasn't too worried about absolute accuracy but having everything in sync is more important. We found the CHT were +- 3 degrees F and the EGT seem to be within 5 or so, although hard to test as they are more sensitive with less damping than the CHTs.
