LEAT SpA, is a Globavia Group company. It is controlled by Globavia SpA (65%) and by Global Aerospace Services Inc. (35%). LEAT provides design, manufacturing and qualification of avionic equipment, new product technology insertion, upgrading or replacement of obsolete equipment, MR&O services and calibration services. As an EASA 21J certified company, LEAT is also able to design minor and major changes of avionic configurations, interiors and structural repairs on small/large aircrafts. LEAT has also an accredited calibration laboratory (LAT. n. 061 certified by Accredia, the Italian Accreditation Body).

Thanks to its solid experience and perfect understanding of client’s needs, LEAT can respond to the customers with tailored and timely solutions.

LEAT was founded in 1962. LEAT started its activity in overhaul, maintenance and upgrade of communication equipment, instrumentation and audio recorders for military avionic applications. Since the beginning, LEAT core business was focused on maintenance, repair and overhaul of avionic equipment and navigation systems in compliance with EASA Part 145. In 1987, LEAT was acquired by Ciset SpA. In 1992, Ciset merged with Vitro Selenia generating Vitrociset SpA. LEAT has been part part of the Vitrociset group for many years. Since August 2010, LEAT is part of the Globavia Group.

Keeping a strong focus on its original activity, LEAT current business is also represented by design, manufacturing and qualification of avionic equipment and/or systems; new product technology insertion; upgrading or replacement of obsolete equipment and product enhancement. Last but not least, LEAT is involved in some important R&D programs for military and civil application.

LEAT excellence becomes tangible through its engineering creations:

Universal Adapter
The Universal Analog / Digital Avionics Interface Adapter solves most of the obsolescence problems regarding avionics of an aircraft in which the new equipment (digital interface) must communicate with existing equipment (analog interface). It is made on a modular platform with internal bus connections between the different interfaces in order to achieve the desired conversions. This way it is possible to meet many requirements with a minimal/none aircraft modification (wiring, weight, space encumbrance, etc.) with significant cost and time savings. Suitable for conversions between analog / digital, digital / digital, or analog video signals to digital.

Video Converter
The video converter is a line of products designed and manufactured to meet the customer requirements and intended applications. These types of converters allow to convert analog signals (PAL, NTSC, VGA and STANAG-3350) in digital signals (DVI, SMPTE ) or viceversa. These equipment can be qualified in compliance with DO-178B and DO-254 guidance rules.

Data Converter
The data converter is a line of products designed and manufactured to meet the customer requirements and intended applications. These types of converters allow to convert analog signals in standard digital avionics signals (Arinc 429) or viceversa. These equipment can be qualified in compliance with DO-178B and DO-254 guidance rules.

Avionic Computer
The Avionic Computer is a new device that combines Mission Computer and OPLS System. The avionic computer is equipped with a Core i7 processor and a dedicated frame grabber card that allows the processing of video sources up to 1080p resolution.

Wiring Integration Assemblies
The Wiring Integration Assemblies (WIA), are systems located on the AW609 Tiltrotor. The WIA consist of metallic casting boxes that contain some electrical passive components and wire bundles. These boxes also provide with a suitable circular connectors to interface the aircraft harnesses. Main purpose of the WIA is to locate into closed boxes the relays, diodes, fuses, bussing and grounding terminal boards required for the Electrical and Avionic systems installation in accordance with the applicable Wiring Diagrams. A second purpose of these boxes is to allow and simplify the harnesses system separation in accordance with the FAA recommendations and with the aircraft harnesses architectures. The WIA Shipset for each aircraft consists of 11 boxes, located in different part of the A/C. The Shipset is composed by 10 Part Numbers.

Nacelle Downstop Sensor
The purpose of downstop sensor equipment is to provide the Flight Control Computer with a feedback of the load the nacelles are applying to the downstop when the aircraft is operating in airplane mode. The downstop sensor is composed of six half-bridge strain-gages connected in a full-bridge configuration. Strain-gages will be able to properly measure the stress induced in the vertical web of the downstop striker support by the nacelle conversion to airplane configuration. The downstop sensor comprise an adequate conditioning circuit capable of handling the signals provided by strain-gages.

Crash Protected Mass Memory
The Crash Protected Mass Memory is a rugged Data Storage. The main function of the device will be to storage Data and Video signals provided by DAU, CVFDR or others device. The input signals that will be stored, must be processed in external devices from the CPMM, in this way the input signals are digital data delivered on Serial ATA interface. The signals that can be recorded will be data signals ARINC (429, 573/717), GPS Signals and on request Voice/Video Signals.

Crash Position Indicator
The need to accurately pinpoint aircraft’s location through the use of a Crash Position Indicator (CPI) has been always crucial for any aircraft’s safety. The increasing use of Cospas/Sarsat and Global Positioning System (GPS) has highlighted the need for a CPI which has expanded capabilities. This CPI has integrated GPS and the activation of all system is controlled with integrated gyroscopes that reveal a loss of altitude out of the standard. The CPI can be manually operated via the cockpit control panel. The CPI is compliant with the new regulation on the frequency of transmission.

In addition to the above projects, LEAT has been selected by Trakkacorp as the final assembler of the searchlight Trakkabeam A800 on Agusta Westland aircrafts (AW139 – AW169 – AW189 – AW101). The Trakkabeam A800 searchlight is a fully automated multi-mission searchlight system, with an integrated pan and tilt that can be remotely positioned in both elevation and azimuth. It is the most advanced searchlight available for airborne, marine, law enforcement, search & rescue, firefighting and military applications. Within November 30th 2013 ten systems will be delivered (5 to the Swedish AirForce + 5 AW101 CSAR). After that date, LEAT will be able to release the system with a LEAT P/N and with an EASA Form 1.


As an EASA 145 certified company, LEAT offers avionic maintenance, repair and overhaul service to military and commercial operators.
