Introduction; Use Of The Performance Tables And Diagrams - Diamond DA 40 Flight Manual

Performance DA 40 AFM

5.1 INTRODUCTION

The performance tables and diagrams on the following pages are presented so that, on
the one hand, you can see what performance you can expect from your airplane, while
on the other they allow comprehensive and sufficiently accurate flight planning. The values
in the tables and the diagrams were obtained in the framework of the flight trials using
an airplane and power-plant in good condition, and corrected to the conditions of the
International Standard Atmosphere (ISA = 15 EC / 59 °F and 1013.25 hPa / 29.92 inHg
at sea level).
The performance diagrams do not take into account variations in pilot experience or a
poorly maintained airplane. The performances given can be attained if the procedures
quoted in this manual are applied, and the airplane has been well maintained.

5.2 USE OF THE PERFORMANCE TABLES AND DIAGRAMS

In order to illustrate the influence of a number of different variables, the performance data
is reproduced in the form of tables or diagrams. These contain sufficiently detailed
information so that conservative values can be selected and used for the determination
of adequate performance data for the planned flight.
Where appropriate, any flight performance degradation resulting from the absence of wheel
fairings is given as a percentage.
The installation of the optional fairings on the main landing gear struts and/or nose landing
gear strut has only minor effects on the flight performance of the DA 40. Therefore, no
change applies to the performance tables and diagrams.
