ACS & Slow Flight

Asked by: 1097 views FAA Regulations, Private Pilot

Does anyone has insight as to why the FAA opted to drastically change the standards for slow flight in the new "ACS", from the previous "min controllable airspeed" PTS standard, to what now says that activating the stall warning would be disqualifying?

    This has gone back and forth over the years.

    When I learned in 1970, it was minimum controllable airspeed. At some point, it changed to 1.2 Vso. Then, it changed back to MCA. Now, apparently, it has changed back away from MCA.

    There is nothing which would prohibit an instructor from teaching MCA and then teaching the new 5-10K over Vso in preparation for the practical test.

    The important things are to be familiar with how the airplane feels and what power and control inputs are necessary to maintain control.
