Touchdown! Greaser!
I was reviewing the performance section of my POH and thought the numbers may not be correct since have the aforementioned upgrade. (The plane had the upgrade when I purchased it). But when I checked the manual supplement that came with the STC, it said "no change" for the performance chapter.
The primary changes appear to be for gross weight increase and W&B changes with a few other operational items.
I was surprised. I can see the TAS would be the same at a given RPM, but wouldn't the %BHP be lower at a given RPM? It seems that 50% of a 180hp engine would turn the prop faster than 50% of a 160hp engine.
Actually, all of that was a distraction to my original purpose. I wanted to brush up on %power ratings at various altitudes and RPMs. The manual kept referring to the "CESSNA POWER COMPUTER". Does anyone know where I might find one? The chart only goes up to Std Temp +20c (68f). Most of my flying is more like 80f to 90F+
Or better yet, is this something that could be coded into an I-phone App? (Jesse, are you reading this? I already have your WnB pro and E6B Pro. apps).
