I was a little surprised to see that flying SP in the 109 a checklist is not used
Not sure if it's still the case, but the owner's previous aircraft (a 355N) was flown almost exclusively by one pilot, day in day out and was private use only. If it's the same with the 109, it could explain no checklist as the pilot would be so familiar with it, and would (usually) know exactly how the aircraft had been left from it's previous flight (e.g. rotor brake on/off etc)
