WARNING
See Safety and Installation Guide 124M8686 for guidance on safety and
standard operating conditions.
The procedures show the steps required to make sure the ADTS 405 is serviceable and of the
settings required to test an aircraft system or component in the following notation:
1. All key presses are highlighted in bold and shown as identified on the key-pad.
2. Key presses inside brackets e.g., [MORE], are soft key presses (i.e, function key selections
{F1 to F4} indicated on the display screen).
For further information on a particular ADTS function and using the Help System refer to Section 6 -
Reference and Specification. The help information includes further details of the function and

For a summary of Set-up and Configuration procedures refer to the quick reference charts, at the
end of this section.

3.5.1 Control or Measure Parameter

To change the (displayed) parameter:
a. Value parameters: Press the parameter key e.g, press SPEED/Qc to display airspeed.
b. Rate parameter: Press the associated parameter key followed by the rate key for that
channel. e.g, display airspeed rate, press SPEED/Qc then RATE. ROC/Ps Rate may be
directly pressed without first pressing ALT/Ps.
Note: The displayed parameters depend on the last keys pressed.
To display two parameters:
a. Press each value parameter in turn, e.g, display altitude and airspeed together, press ALT/
Ps then SPEED/Qc.
b. In control mode, an arrow, at the right-hand end of the aim value, indicates the last
parameter selected. This can be changed by entering a new value.
To display a value parameter together with its rate:
a. Press the parameter key followed by the associated rate key, e.g, display airspeed and rate
of speed together, press SPEED/Qc then RATE.
Note: If ROC/Ps Rate is pressed, the display automatically shows ALT and ROC.
See "SETUP RATE", section 6.3, for display details.
Display Functions (Fig 3.2, Fig 3.3 and Fig 3.4)
The display normally shows pressures and rates or aeronautical equivalents. It can be set-up to
show, at the same time, one parameter (single), two parameters (dual) or three parameters (triple).
