1. Foreword
Congratulations, you are now using the most modern and convenient means to check your aircraft
tire pressures! This manual will help you make the most of the W TPS.
WTPS stands for W ireless Tire Pressure Sensor.
This manual is intended for actual users of the WTPS system, oncethe system is installed on aircraft.
Maintenance staff looking for installation and removal instructions on aircraft should refer to the WTPS
installation and removal manual.
Using theWTPS requires a smartphone (or tablet, or any other compatible device –collectively called
smartphone in this document) running the appropriate mobile application from your aircraft
manufacturer (calledApp in this document). The tire pressure toolin thisApp isonlyavailable for Apple
iOS devices at the moment. To enquire about availability of a tire pressure tool compatible with
Android TM mobile devices, please liaise with your aircraft manufacturer.
Once the App is installed, enter the WTPS menu by tapping on the Tire Pressure icon:
This manual is purely about the WTPS and its interaction with the application. Issues with the
smartphone or the App itself are not dealt with in this document. For any issues with the smartphone
or the App, liaise with your smartphone manufacturer or Textron Aviation respectively.
Screenshots in this document come from Textron Aviation Service App version 5.9. Details may vary in
subsequent versions.
2. WTPS facts
The WTPS uses Bluetooth®Low Energy v4.2. Your smartphone must be compatible (v4.2 or higher) and
the Bluetooth®must be enabled.
The W TPS is intended for use on ground only, on a parked aircraft. It is not intended for use in flight or
on a moving aircraft.
The WTPS operates between -20°C and +70°C(-4°F and +158°F). Outside this range, the WTPS does
not transmit over Bluetooth®in order to preserve its battery. However the WTPS can withstand without
damage temperature between -55°C and +140°C (-67°F and +284°F).
Tire servicing must be accomplished accordingto the aircraft and/or tire manufacturer procedures.
An important message is displayed on the App at first use. The WTPS can only be used if this message
is read, understood and agreed. Failure to read, understand and comply with this message may lead
to unsafe aircraft operation.
The WTPS is designed for a two-year service life. It is powered by a non-rechargeable battery.

4. Usage
The W TPS can only be used once the WPTS has been installed on aircraft and the sensors have been
configured.
1. Activate the Bluetooth® interface on the smartphone
Note: Some smartphones require activating the localization feature for the Bluetooth® to work
properly.
2. Make sure the sensors are within Bluetooth® range
Note: The communication range depends on the smartphone, on the environment and on the
potential presence of obstacle (e.g. the fairing covering the sensor on the wheel).
3. On the Smartphone app, go to the Find an aircraft menu
4. Select an aircraft from its tail number
