Test & measurement I
n an industry like aerospace, precision is key when it comes to safe and efficient operations. Accurate measurements for qualities like fuel efficiency, structural integrity and cargo
management keep safety and performance in check - avoiding cost spikes or even dangerous scenarios for an aircraft. According to the FAA’s Weight and Balance Handbook, weight and balance holds vital importance to each FAA certificated mechanic or technician maintaining an aircraft. Consequently, they must be fully aware of their responsibility to provide the pilot with current and accurate information for the actual weight of the aircraft and the location of the centre of gravity (CG).
THE TRANSITION TO WIRELESS
As modern aircrafts continue to evolve in complexity, more efficient and reliable weighing solutions are necessary. Historically, weighing systems relied on wired technology, which is less flexible in terms of placement and movement, making it harder to adapt to different aircraft types and configurations. Wired systems also experience more wear and tear compared to wireless systems as physical cabling and connectors are prone to environmental damage and mechanical stress. Over time, it can lead to connectivity issues and require more frequent repairs, which increases downtime across weighing operations. Wireless weighing set ups
SOARING TO NEW HEIGHTS
IN AIRCRAFT WEIGHING
The aircraft weighing operation is stringent. Crew are often frantically weighing planes with outdated equipment, manually calibrating kit and dealing with consistent errors and inefficiencies across the process. But in recent years, the aviation industry has implemented new wireless monitoring systems into aircraft weighing, in efforts to improve efficiency and precision. Here, Tom Lilly, product manager at wireless telemetry specialist Mantracourt, explores the move towards digital monitoring methods, and how wireless telemetry systems are being integrated into aircraft weighing methods.
like Mantracourt’s T24 wireless telemetry system address many challenges associated with wired weighing equipment. A simplified set up with no cabling allows for reduced time spent on calibration and repairs, even integrating with existing infrastructure for a smoother system transition. It also creates flexibility for sensors to be placed in optimal positions without cabling restrictions, a valuable tool when weighing some larger aircraft.
Additionally, with many wireless systems built to withstand harsh conditions, they provide increased durability and longevity. They often feature IP67 rated components that can be critical for equipment used in diverse conditions.
Removing cables is not the only benefit when it comes to using wireless telemetry systems. They bring together additional qualities that enhance their appeal to aircraft weighing operators. It enables real-time monitoring
which means operators can read live data and make immediate calculated decisions based on accurate readings. These readings also allow for custom alerts for under or over-range conditions, meaning operators can be notified when aircraft weight distribution is safe.
