condition.
Align To bring into line; to line up; to bring into precise adjustment, correct relative
position or coincidence.
Assemble: To fit and secure together the several parts of; to make or form by combining
parts.
Calibrate: To determine accuracy, deviation or variation by special measurement or by
comparison with a standard.
Check: Make a comparison of a measure of time, pressure, temperature, resistance,
dimension or other quality with a known figure for that measurement.
Disconnect: To detach the connection between; to separate keyed or matched equipment
parts.
Dismantle: To take apart to the level of the next smaller unit or down to all removable parts.
Examine: To perform a critical visual observation or check for specific conditions; to test the
condition of.
Fit: Correctly attach one item to another.
Inspect: Review the work carried out by Specialists to make sure it has been performed
satisfactorily.
Install: To perform operations necessary to properly fit an equipment unit into the next
larger assembly or system.
Maintain: To hold or keep in any particular state or condition especially in a state of
efficiency or validity.
Make sure: To confirm that a proper condition exists; to find out with certainty.
Operate: Make sure that an item or system functions correctly as far as possible without
the use of test equipment or reference to measurement.
Power-up: To perform operations necessary to switch on a system ready for use.
Glossary

Table of pressure units and conversion factors
Unit Conversion
To convert FROM pressure VALUE 1 in pressure UNITS 1
TO pressure VALUE 2 in pressure UNITS 2, calculate as follows:
VALUE 2 = VALUE 1 x FACTOR 1
FACTOR 2
Note
The conversion factor for pressure units referenced [1] are calculated for a water temperature of 4°C.
Pressure units referenced [2] are calculated for a water temperature of 68°F these units are normally
used in the USA.

1 DESCRIPTION
1.1 Introduction
There are two versions of the ADTS 405, a 19", 6U high (10½”) rack-mounted unit and a
flight line unit.
The ADTS 405 is a rack-mounted system and, with external pressure and vacuum supplies
connected, provides measurement and control for leak checks, calibration accuracy
checks and functional tests of air data instruments, components and systems.
The ADTS 405F is a self-contained flight-line air data test system providing complete
pressure and vacuum measuring and control for on-aircraft sense and leak testing,
calibrationaccuracy checksand functional tests of air data instruments, components and
systems. Theunit comprises an electronics rack and pumprack enclosedin ahigh density,
polyethylene case.
TheADTS405displaysandoperatesineitherunitsofpressuremeasurementoraeronautical
units. In the control mode, the rate that the pressures change towards new set-points can
be controlled in true aeronautical rate units.
There are two independent pneumatic channels connect to the aircraft or instrument
systems, one for static and one for pitot. They can be operated as measure only channels
with leak testing facility or each can be control channels producing true pressure
conditions for altitude and airspeed.
To protect sensitive instruments and equipment a `ground' facility automatically and
safely controls both channels to atmospheric pressure at the previously entered rates of
change and then informs the operator when both channels are safely at `ground'.
The operator interface is either an ATEX certified hand terminal connected to the front
panel or the key pad and display on the front panel. Both provide information and control
selections for the user through the keys and display. The unit can also be controlled
remotely using the IEEE 488 communications interface. The front panel contains the
operate switch and a mimic panel with LED indicators showing the operation of the
solenoid-operated pneumatic valves.
The pump rack, on the ADTS 405F, produces pressure and vacuum supplies for the
electronics rack and for external services. Located on the front panel, the external
connectors provide for external pressure and vacuum supplies (EXT PRESSURE and EXT
VACUUM)and anauxiliary static(vacuum) output(AUX). The rackis cooledby a fan located
under a protective cover on the front panel. The power supply connection for the ADTS
405F is located on the front panel.
