Note: Do not use unauthorized sources to service this equipment as this will affect the
warranty and may not guarantee further performance.
There are two versions of this Air Data Test System, a 19", 6U high (10½”) rack-mounted unit (ADTS
405R) and a flight line unit (ADTS 405F).
The ADTS 405R is a rack-mounted system and, with external pressure and vacuum supplies
connected, provides measurement and control of pitot and static systems and components. The
unit can be used 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 pitot and
static measurement and control. The unit can be used for on-aircraft sense and leak testing,
calibration accuracy checks and functional tests of air data instruments, components and systems.
The ADTS 405F comprises an electronics rack and pump rack enclosed in a high density,
polyethylene case.
The ADTS 405 displays and operates in either units of pressure measurement or aeronautical 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 a 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 keypad has a back-light for improved operation in poor light conditions. The
unit can also be controlled remotely using the IEEE488 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 an auxiliary static (vacuum)
output (AUX). The rack is cooled by 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.
1.2 Operating Range and Performance
The ADTS 405 is supplied in one of two full-scale ranges (850 knots or 1000 knots) for
measurement and control of the pitot pressure channel.
Operating limits are set, pre-defined tabular limits known as STANDARD, CIVIL and MAX these can
be selected through the SETUP menu (see Reference section 6). 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.
Please keep the special packing boxes so that the ADTS can be safely shipped for calibration, repair
or storage.

2.2 Packaging for Storage or Transportation
WARNING THE FLIGHT-LINE UNIT CAN BE MOVED BY USE OF THE HANDLE AND
WHEELS, BUT IF IT IS TO BE LIFTED, IT IS A TWO PERSON LIFT.
Environment
The optimum conditions for ADTS405 Mk2 equipment during transit, preparation for calibration and
repair and when being storage are detailed as below. Items in storage are defined as being nonoperational. If the ADTS becomes exposed to moisture or very high humidity, dry as soon as
possible and temporarily store in a low humidity area. The following conditions apply for storage or
shipping:
Temperature Range-51° to 70°C (-60° to +158°F)
AltitudeUp to 50,000 feet (15,240 metres)
Procedure
1.The unit should be at zero/ambient pressure.
2.Disconnect all hose assemblies and stow them in the shoulder bag.
3.Switch power OFF and disconnect from the electrical power supply.
4.Disconnect the power supply cable and the hand terminal cable.
5.Disconnect the hand terminal cable from the hand terminal.
When using packing materials other than the original, proceed as follows:
1.Wrap unit in polyethylene sheeting.
2.Select a double-wall cardboard container. Inside dimensions must be at least 15 cm
greater than the equipment. The carton must meet test strength requirements of >125 kg.
3.Protect all sides with shock-absorbing material to prevent equipment movement within
the container.
4.Seal carton with approved sealing tape.
5.Mark carton “FRAGILE” on all sides, top, and bottom of shipping container.
Note: For ADTS 405R rack units loose or peripheral items should be placed in a
sealed polythene bag. For ADTS 405F stow the power supply cable, hand
terminal cable and the hand terminal in the ADTS 405F lid. Fit the lid to the
unit.

Power Supply
1.The unit must be connected to the correct electrical power supply as stated, beside the
power connectors on the rear panel.
2.Install an easily accessible isolator in the power supply circuit.
3.The power supply connector on the rear panel of the unit will not be accessible when fitted
in the equipment rack.
Note: The power supply switch on the front panel is not classified as a
disconnecting device.
On the ADTS 405R, two 20mm High Breaking Capacity fuses are located in the holder mounted on
the power input connector on the rear of the rack and protect the entire unit. The fuses are
connected in the live and neutral supply circuit and are: T5A/250V HRC type. Only replace the fuses
with the correct type, see Figure 2-1 item 11 section 4-4.
2.3.2 405F Flightline version
1.The power switch on the front panel is not a power isolator as defined by EN61010. To
isolate the power supply disconnect the power supply connector.
Fuses AC Power
The fuses fitted in the fuse holders on the front panel are: T5A/250V HRC type. Only replace a fuse
with the correct type, see Figure 2-1, item 11. To replace a fuse see Section 4-4.
Fuses DC Power
The fuses fit in the fuse holders on the front panel are either: T20.0A/250V HRC type (on the left) or
T32A/250V HRC type (on the right). The DC power option (nominal 28 V DC), can be an alternative
power supply using an additional connector located on the pump front panel. Only replace a fuse
with the correct type, see Figure 2-1, item 11 To replace a fuse see, Section 4-4.
CAUTION A protective EARTH connection must also be made for DC operation or
specified EMC performance may be impaired.
2.4 Positioning of the ADTS
2.4.1 405R Rack-mounted version
It is important that the position of the ADTS 405 in relation to the UUT is known. An altitude
correction must be made to allow for the difference in height between the reference level, indicated
on the mimic panel, and the UUT. The Reference section contains details of altitude correction
(SETUP, ALTITUDE).
WARNING OBSERVE THE APPROPRIATE SAFETY INSTRUCTIONS AND PROCEDURES
DETAILED IN THE AIRCRAFT MAINTENANCE MANUAL AND COMPONENT MAINTENANCE
MANUALS.
It is important that the position of the ADTS 405F in relation to the aircraft altitude sensors is
known. An altitude correction must be made to allow for the difference in height between the
reference level and the aircraft's altitude sensors. The Reference section contains details of altitude
correction (SETUP ALTITUDE).
