GENERAL
Hawker 800XP Pro Line 21
Section IV - FLIGHT PLANNING DATA
INTRODUCTION
This Sub-section contains general speed and atmospheric data. It also contains ceiling data giving the
relationship between maximum altitude and maximum weight. It also contains relationships between
true Mach number, true airspeed and true outside air temperature with indicated values of airspeed,
altitude and temperature.
The true Mach number on the graph differs slightly from the indicated Mach number by the magnitude
of the position error given in Sub-section 5.05 of the Airplane Flight Manual.
It also provides ceiling data which will give maximum altitude for a given weight or weight for a given
altitude.
The limits are determined by the most critical of two considerations:
• The maximum cruise altitude of 41,000 ft.
• Ability to climb at 200 ft/min at 0.7M.
Data for buffet margins is provided in the Airplane Flight Manual Sub-section 5.05, Figure 5.05.7.
