Low power operation (Piston) ??
Hi folks,
My company operates a fleet of Lycoming O540 powered aircraft (Piper Lance) for joyflight/sightseeing operations.
Company SOP's require us to fly at a very low power setting all in the name of longer engine life and increased specific air range.
Typical power settings are 22"/2200rpm leaned to about 800c EGT and 11 USGAL/HR at 1000' (about 50-55% power i think)
Is this a flase ecomony ??
As far as im concerned, these engines are designed to run at much higher power settings - do they operate well at such low settings ?
Will 'running in' engines at this low power setting cause cylinders to glaze ? If so, what are the long term effects of using these power settings ?
Any info greatly appriecated !
