Key Takeaways:

The article advocates for Lean of Peak (LOP) EGT cooling, explaining its mechanism of cooling with air instead of fuel, while noting the necessity of balanced engine operation and proper pilot understanding for its effective implementation.
It discusses the semantic debate between using "crash" versus "accident" for aviation events, exploring historical context for terminology shifts and the editor's adherence to the NTSB definition, ultimately viewing the distinction as less significant than the prevalence of such events.

Hover Mode Cooling

Having long been a lean of peak (LOP) exhaust gas temperature (EGT) advocate (25 years), I think some further explanation to Andrew Strauss and some of your other readers about that form of mixture control might be in order (Unicom, August 2024).

First of all, not everyone has mixture distribution that is well balanced enough between all their engine’s cylinders to run lean of peak with smooth engine operation. If they do, then it should definitely help.
