Installation design and modernization of aircrafts' avionics

 
As a result of dynamic development of technology and wide rage of products offered by avionics manufacturers there is great demand for aircraft modernization including new avionics equipment in order to improve pilotage comfort and flight safety.

Drabpol, designs and modernisations
The only one in Poland

In order to satisfy the needs of aircraft users, Drabpol created first design office in Poland where designing of avionics equipment changes on aircrafts is performed.

We have Approved Maintenance Organization in accordance with PART 21 focused on avionics electronic systems for aircrafts certified in CS 23 categories (normal, utility and acrobatic category aircrafts with MTOW up to 5670 kg and twin-engine, commuter category 3 175 kg).

We prepare aircraft avionics modifications projects which meet requirements specified by EASA.

We develop STC documentation or Minor Change required during installation of new equipment on aircraft depending on change complexity in respect of technical and essential aspects.



 
 
 

STC/Minor Change development includes:
- technical documentation (electrical diagrams, drawing documentation, energy balance, balance analysis),
- operation manual (flight manual supplement),
- trial programs including ground testing and flight testing.

With support of our own PART 145 team during our work focused on avionics modernization we have the possibility to perform simultaneous installation of new equipment on the aircraft as well as ground testing and flight testing.

First in Europe

 
The most popular helicopter in Poland and top selling in Europe + equipment which does not constitute its standard equipment but is considered a part of standard equipment in majority of new light aircrafts... We took up the challenge! As the only company in Europe we developed modernization, performed the installation, testing and certification of Avidyne’s TAS 615 collision avoidance system and TWX 670 lighting detection system on Robinson R44 II Raven helicopter.

BEFORE

Any aircraft modifications are not only performed in accordance with EASA requirements but also approved by EASA.
 
Any works we perform are based on aircraft technical documentation developing which as a result is verified and approved by issuance of STC certificate by EASA.

AFTER

Finished project includes design documentation referring to installation of device and completion of aircraft operating documentation.

Next, the modification of avionics and electric equipment together with mechanical installation is performed on the aircraft on the basis of possessed documentation and authorizations in the line maintenance facility in Modlin. In the picture- traffic advisory system (TAS 615) and tactical weather detection system (TWX 670) on MHD 300 display in new R44 panel.

Our engineers work on modern CAD systems (computer aided design) creating 3D models of components in the field of modification. Thanks to CNC machine tool owned by PART 145, previously designed installation elements and panel are manufactured internally.

We also work on projects to be implemented by other operating organizations in Poland and Europe and complete projects – starting from idea, documentation to training stands for flight schools.

Ongoing projects:

  • Development of Avidyne's TAS615 system on Robinson R44 helicopter
  • Development of Avidyne's TWX670 on Robinson R44 helicopter

All projects are subject to internal control and consistent with valid standards and regulations.

Office work requires active involvement of not only constructors but also designers, graphic designers, electronics engineers and mechanics. Teamwork makes possible to develop optimal project in order to meet customer’s requirements referring to construction, graphics and esthetics.

On each stage of our projects we take care and provide the highest quality. For his reason we employ only experienced constructors and use specialty software.


The office works on the basis of procedures included in the ISO, AQAP quality systems, requirements of Civil Aviation Organization for PART 21 design organizations.
