Avionics Division

The activity of Avionics Division is focused on research & development, design & engineering, and short ‑ run manufacturing in the area of avionic equipment and systems, measuring and diagnostic systems, as well as electric systems and installations for airplanes, helicopters and unmanned air vehicles (UAVs). One of the units of the Avionic Division is the Laboratory of Environmental Tests, certified by the Polish Centre for Accreditation.

The Avionics Division has been engaged in national and international projects (ERA, EPATS, SOFIA, Super SKYSENSE, CESAR).

The Avionics Division has the power of Manufacturing Organisation and Servicing Organisation.

The Servicing Organisation of the Institute of Aviation, confirmed by Civil Aviation Authority in Poland due to the Disposal of European Parliament and Council of Europe no. 216/2008 and the Disposal of European Commission no. 2043/2003 according to the Chapter A of the Annex II (Part‑145), is allowed to perform servicing procedures of parts and equipment listed in aforementioned documents of approval, and to issue the appropriate documents of performed servicing procedures in the form of EASA FORM 1 document.

The Avionics Division declares the capability to carry on projects focused on design and development within the following areas:

Systems aimed at aircraft and RPAS motion within the controlled airspace during each phase of flight;
Avionic systems, especially for classical, remote and/or automatic flight control and stabilisation, for RPAS, satellites and other systems.
Avionic equipment for measuring flight parameters (e.g. CDA, radio‑altimeter), spatial position (e.g.: INS, AHRS) and other parameters (e.g. fuel gauging system);
Mathematical modelling of flying object’s motion;
Design of microprocessor units – specialised data transforming interfaces for measuring units and stabilising, control and diagnostic systems, especially for avionic equipment, RPAS, satellites and other units and/or sub‑systems which need computing platforms for numerical algorithms implementation;
Prototyping of avionic units, assembling and certified manufacturing for commercial users;
Investigations and tests of durability and resistance of units and technical installations, especially aerial and avionic systems and also other systems and sub‑systems designed in the Institute of Aviation which need such investigations, to the effect of mechanical factors (vibrations and shocks) and climatic factors (ambient temperature, high humidity, low pressure).

Expert evaluations, references, products

Avionic Division is capable to prepare expert evaluations and opinions for aircraft equipment, systems and installations, concluded with written opinions on compliance with the following standards and regulations: RTCA, ARINC, MIL, TSO, DO-160C.

Products designed and manufactured in Avionic Division are installed on many polish aircrafts. The following are worth a special attention:

the autonomous recorder of fatigue loads data – AROS,
Testing instruments for on‑board radio‑transceivers TRS 6113‑2, fuel gauging systems TPPM‑1, radio‑altimeters T4S, torque‑meters UD‑100M, and radio‑navigation systems MRT-3.

Laboratory of Environmental Tests

In February 2007 the Laboratory acquired the Testing Laboratory Certificate No. AB 132, issued by Polish Centre for Accreditation, in compliance with PN‑EN ISO/IEC 17025:2005 standard requirements. The scope of this Certificate covers tests of robustness to mechanical hazards, climate stresses and functional inspection of products.

The laboratory is capable to carry on tests of products for military applications within the frames of the system of management satisfying the AQAP 2110:2009 regulations, as well as products for the army and/or police for special use within the range defined by the Licence No. B‑003/2010 obtained from the Ministry of the Interior and Administration.
