WL102AMS6 - Textron Aviation OEM Proprietary Altimeter and Airspeed Standby Indicator for Citation Jets

WL102AMS6 – Textron Aviation OEM Integrated Electronic Standby Instrument

Available now on the Airparts.aero Marketplace.

Overview

The WL102AMS6 is a genuine OEM, flight-critical Integrated Electronic Standby Instrument (IESI), a sophisticated "all-in-one" glass display unit engineered for the flight decks of numerous Cessna Citation business jets. While the user's description notes Altimeter and Airspeed, this unit provides a far more comprehensive backup. Manufactured by industry leaders like Thales Avionics to Textron's exact specifications, this self-contained instrument is designed to provide the flight crew with a completely independent and redundant source of primary flight data. In the event of a failure of the main glass cockpit displays, the IESI provides attitude, altitude, airspeed, and heading information, ensuring the pilot can maintain safe control of the aircraft.

Key Features

• Integrated 3-in-1 Display: Combines the functions of three separate standby instruments—Attitude Indicator, Altimeter, and Airspeed Indicator—into a single, compact, and highly reliable glass display unit. It often includes heading and navigation data as well.
• Solid-State Reliability: Utilizes a high-resolution Active Matrix Liquid Crystal Display (AMLCD) and solid-state Attitude and Heading Reference System (AHRS) and Air Data Computer (ADC) sensors. With no moving parts like gyros, it offers exceptional reliability and a long service life.
• Dissimilar & Independent Operation: Engineered to be completely independent of the aircraft's primary flight displays and their associated sensors. This dissimilarity is a critical safety feature, ensuring that a single-point failure (like a primary ADC or AHRS failure) will not affect the standby instrument.
• Internal Battery Backup: Features an integrated, dedicated backup battery. In the event of a total aircraft electrical failure, the IESI will automatically power itself for a specified duration (e.g., 30+ minutes), providing the crew with the essential data needed to control the aircraft.
• Genuine Textron OEM Part: As a genuine factory component, it guarantees seamless software and hardware integration with the Citation's pitot-static, electrical, and navigation systems, ensuring fully certified, airworthy performance.

Applications

The WL102AMS6 is a flight-critical safety system with a singular, vital purpose:

• Standby Flight Reference: In the event of a failure of the primary PFDs/MFDs, this unit becomes the sole source of attitude, altitude, and airspeed information for the flight crew, enabling them to safely aviate and navigate to a landing.
• Regulatory Requirement: The presence of a functional, independent standby instrument system is a mandatory certification requirement for transport-category and technically advanced aircraft.

Why Choose WL102AMS6?

In a modern glass cockpit, the potential for a cascading failure or a simple screen blackout is a significant risk. The WL102AMS6 is the engineered, fail-safe solution to this problem. It is a "get-you-home" instrument of last resort. Using a genuine Textron OEM unit is the only way to ensure the instrument has the correct software configuration, calibration, and interface compatibility with your specific aircraft model. For a system this critical to surviving a major avionics failure, there is no substitute for a fully certified, OEM component.

The WL102AMS6 is a self-contained flight information system. It receives inputs from its own dedicated internal solid-state gyroscopes and accelerometers to calculate and display aircraft attitude. It also connects directly to the aircraft's pitot-static system, using its own internal pressure transducers to independently calculate and display airspeed and altitude. This complete sensor independence is the cornerstone of its design. A failure in the primary Air Data Computers (ADCs) or Attitude and Heading Reference Systems (AHRS) that feed the main displays will have no effect on the WL102AMS6, providing the pilot with a trusted and completely separate set of data to fly the aircraft.

Note: This is a flight-critical avionics component. Installation, configuration, and testing must be performed by a certified Part 145 repair station or a qualified avionics technician in strict accordance with the current Textron Aviation maintenance manual. Regular testing of the internal battery is a required maintenance task.
