A calibrated tachometer should be used to compare required static rpm
listed on type certificate data sheets to the specified minimum or maximum full throttle rpm.
One owner told us that the static RPM
increase on his 172 at nearly sea level demonstrated an increase in four HP using traditional horsepower versus RPM change calculations.
(piston craft) must be at or above the expected number or abort.
For example, a Cessna 172 Skyhawk with a cruise prop likely will have a lower static rpm
and reduced takeoff and climb performance.
For a fixed-pitch prop, you should see full static RPM
Several sent in detailed before and after results, including static RPM readings, fuel flow, time-to-climb and full-throttle cruise speeds.
I found that my static RPM had gone from the low end of the allowable range to the high end, an increase of 150 RPM.
The letters stand for: RPM-ensure it's full-rated RPM, or expected static RPM
for a fixed-pitch prop; Engine gauges in the green; Airspeed is alive; Centerline of the runway ('cause you've been looking down for a couple seconds, you should make sure you're not about to abscond with a runway light); Takeoff (rotation) speed will be achieved before a preselected abort point.
If your airplane/prop combination is fixed-pitch, the TCDS also will include static RPM
