The Fluke 7750i Air Data Test Set stands out as a pinnacle in aviation calibration technology, offering high accuracy and reliability for air data systems. This sophisticated equipment is designed to meet stringent requirements, making it an ideal choice for Aircraft Test Equipment (ATE) systems. Let’s delve into the key features and benefits that make the Fluke 7750i a trusted companion in the aviation industry.

Key Features

The Fluke 7750i boasts impressive features, including its high accuracy and compliance with Reduced Vertical Separation Minimum (RVSM) standards. With an accuracy of ±3 feet and 0.04 knots, this test set ensures precision in air data calibration. Moreover, its true differential sensor for airspeed measurement and control stability to 0.00032 contributes to its exceptional performance.

Ideal for ATE Systems

The Fluke 7750i is designed to integrate into Aircraft Test Equipment (ATE) systems. This compatibility enhances the efficiency of calibration processes, making it a valuable tool for aviation maintenance and testing protocols. Its seamless integration streamlines workflows and ensures that air data systems meet the stringent standards set by aviation authorities.

Differential Sensor Technology

One of the standout features of the Fluke 7750i is its true differential sensor for airspeed. This technology allows for precise and reliable measurements, critical for the accurate calibration of air data instruments. The differential sensor sets the Fluke 7750i apart, ensuring that it meets the demanding requirements of the aviation industry.

Control Stability

The control stability of the Fluke 7750i is a testament to its engineering excellence. With a control stability of 0.00032, this air data test set provides a stable and controlled environment for calibration procedures. This level of stability is crucial in guaranteeing the accuracy and reliability of air data measurements, contributing to the overall safety and performance of aircraft.

Fluke 7750i Air Data Test Set Specifications:

  • Automatic Go to Ground: Upon selecting the go-to-ground command, the Fluke 7750i safely controls the pressure to the current, local barometric pressure. The user can then disconnect the device under test (DUT) without exposing sensitive instruments to a potential pressure transient or shock.
  • Leak Test Mode: A separate mode is provided for performing leak checks before beginning an actual calibration.
  • Protecting the Device Under Test: To protect the DUT, the operator can program high and low limit settings for:
    • Altitude
    • Airspeed
    • Rate of climb
    • Mach
    • Negative Qc
    • ARINC 565 envelope
  • Automatic Volume Characterization: The 7750i automatically tunes the controller into external volumes ranging from 5 to 60 cubic inches (80 to 1000 cc). This allows a large degree of flexibility for the configuration of the test system and the type of aircraft and components to be tested. For component manufacturers, a large number of devices can be tested simultaneously on a single manifold.
  • Automatic Zeroing: As with any instrument, regular zeroing is suggested to achieve maximum performance. This task is now automated and can be performed at the push of a button, or over the PC interfaces. The 7750i incorporates the vacuum sensor onboard; no separate or external vacuum gauges or sensors are required. In addition, only one vacuum pump is required to operate and zero the 7750i ADTS. Zeroing is performed in 30 to 45 minutes using the specific vacuum pump.
  • Avionics and Pressure Units: The Model 7750i displays the common avionics units including feet and meters for altitude, calibrated airspeed in knots, km/hr, and Mach with corresponding rate displays for each unit per minute. It can also display pressure units.
