Eng Temp Limits
All engines have their temperature limits. Exceed them and you risk damaging the engine. So, can someone explain the following quote from the latest Defence Helicopter:
"Ingenuity has characterised efforts to keep the UK's helicopters running in Iraq. The Sea King HC Mk4s have had their engines upgraded to enable them to lift an extra 1360kgs at temperatures of up to 50 degC, by taking the engine temperature measurements from an alternative source to convince the engine that it is operating at a cooler temperature."
So, if the engine was temping out before the mod, how can it operate at the higher temperatures? Admittedly the TBO for the engines is now 150-200 hours.
