Measurement and Control Range Specifications
Operating Range and Performance
Limits are set pre-defined tabular limits known as ARINC 565, CIVIL and EPR these can be selected
through the SETUP menu. Operators may also configure the display to aeronautical or pressure
units but should be aware that when units of pressure are selected, wider full-scale pressure limits
will be enabled for some parameters.
Performance expressed in aeronautical units
NOTES
(1) Maximum operating range that can be achieved using the internal pump at airfield
altitudes to a maximum of 7,500 ft above sea level.
(2) Accuracy at ambient +5° to +35°C.
(3) Not all combinations are available to prevent excessive Mach number. For the Mach
number 2.8 limit to be maintained:
Altitude of 60,000 ft means a CAS limit of 590.2 knots.
Airspeed of 650 knots means a limit of 55,147 ft.
