In my opinion the RPM response of the stock C172 to any movement in the throttle is delayed by a factor of ten, or possibly more.
In a normally aspirated, fixed pitch aircraft, the RPM should follow the throttle setting with probably no more than .25 second delay. Instead, I see something like a 3-4 second delay when changing the throttle setting from slow cruise of 2100rpm to the desired 1800rpm for follwing an ILS glideslope. This is both unrealistic and distracting and I would like to change it.
Anyone know how I can change this parameter?
