4.1 Introduction
Chapter 4 contains data on airspeed calibration (position error of airspeed
indicator), on minimum flying speeds and data on take-off characteristics.
The data are based on particular flight measurements undertaken with the
aircraft of this type under normal conditions and with application of average
piloting technique.
4.2 Performance
