6.4 Measurement and Control Range Specifications

WARNING
THIS EQUIPMENT IS NOT RATED FOR USE IN POTENTIALLY EXPLOSIVE AND
HAZARDOUS ATMOSPHERES.
Operating Range and Performance
Both ADTS 405F and ADTS 405R are supplied in one of two full-scale ranges (850 knots or 1000
knots) for measurement and control of the pitot pressure channel. The following operating
parameters are based on a 1000 knots capability test systems. Variations for 850 knots test
systems are shown, where appropriate, in brackets.
For both full-scale ranges, limits are set pre-defined tabular limits known as STANDARD, CIVIL and
*MAX these can be selected through the SETUP menu.
Note: The ADTS is supplied without *MAX limits, a prompt in the SETUP limits
menu asks for MAX limits to be created. This function automatically loads the
maximum values appropriate for the full-scale range. 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.

a. Altitudes above 80,000 ft and the peak rates of climb are available but subject to the use
of a suitable vacuum pump.
b. Accuracy, (expanded uncertainty K=2); includes Non-linearity, Hysterisis and
repeatability over full temperature range, 12 months drift and calibration standard
uncertainty.
c. The accuracy figures stated assume Auto-Zero function is enabled.
