MEGGiTT WTPS Wireless Tire Pressure Sensor

MEGGiTT-WTPS-Wireless-Tire-Pressure-Sensor-PRODUCT

Wireless Tire Pressure Sensor

The WTPS is a wireless tire pressure sensor designed to help you check your aircraft’s tire pressures in a modern and convenient way. This manual is intended for actual users of the WTPS system, once the system is installed on the aircraft. Please note that maintenance staff looking for installation and removal instructions on aircraft should refer to the WTPS installation and removal manual.

WTPS Facts

The WTPS is designed for a two-year service life and is powered by a non- rechargeable battery. Tire servicing must be accomplished according to the aircraft and/or tire manufacturer procedures. An important message will be displayed on the App at first use, which must be read, understood, and agreed to before using the WTPS. Failure to do so may lead to unsafe aircraft operation.

Applicability

This document applies to the following part number(s):

423-420-099-021
423-420-099-022

The sensor part number can be found on the sensor itself or via the App in the Device information.

Usage

The WTPS can only be used once the WPTS has been installed on the aircraft and the sensors have been configured. Please note that the communication range depends on the smartphone, environment, and potential presence of obstacles (e.g., the fairing covering thesensor on the wheel).

On the Smartphone app, go to the Find an aircraft menu.
Select an aircraft from its tail number.
Type in the local altitude in feet (or let the app automatically find it if the required authorizations are granted).

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 WTPS.
WTPS stands for Wireless Tire Pressure Sensor.

This manual is intended for actual users of the WTPS system, once the 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 the WTPS 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 (called App in this document). The tire pressure tool in this App is only available 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.

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 WTPS 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 according to 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.

Applicability

This document applies to the following part number(s):

423-420-099-021
423-420-099-022

The sensor part number can be found on the sensor itself, or via the App in the Device information

Usage
The WTPS can only be used once the WPTS has been installed on aircraft and the sensors have been configured.

Activate the Bluetooth® interface on the smartphone
Note: Some smartphones require activating the localization feature for the Bluetooth® to work properly.
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).
On the Smartphone app, go to the Find an aircraft menu
Select an aircraft from its tail number
Type in the local altitude in feet (or let the app automatically find it, if the required authorizations are granted).
The pressure measured by all sensors of the selected aircraft are displayed in PSI
Tap on a wheel and then on Device info to see additional data (e.g. sensor temperature, part numbers, etc)

Note: The smartphone app provided is a beta version, for test and development purposes only. It is not fully representative of the final app provided to the end users, especially in terms of data integrity, fool proofing and user-friendliness. Some errors that do not prevent from evaluating the product may be found.

Sensor disposal

The WTPS sensor contains a battery and electronic circuitry. At the end of its service life, the WTPS sensor should be recycled. Battery-powered devices must be recycled or disposed of separately from conventional waste. Dispose of batteries according to your local regulations.
