Technical Advisory Committee (TAC)


The role of the TAC is defined in Article 17 of the EUROCAE constitution. In addition to giving advice to the Council, it provides recommendations on the creation and modification of new standardisation activities, namely Working Groups. TAC is composed of 12 members that represent the different stakeholder groups in EUROCAE. The Secretariat is also a key participant in the TAC. TAC Members are appointed by the Council for 3 years, any EUROCAE member can apply.


The TAC meets roughly four times a year, synchronised with Council meetings so as to allow a fast flow of information. During its meetings, it monitors the progress of the Working Groups and looks into what actually happens in the standardization world outside at RTCA, EASA, SESAR, ICAO. This work is done in close cooperation with the Secretariat.

Most intense debates happen about the start of new WGs or follow-up work for existing WGs. It has to make sure to align the work with the activities of other bodies (especially RTCA and SAE), with the needs of European Industry, and sometimes to prioritise in order to make best use of scarce resources of members.

Once a year, the collective experience of TAC members is brought into the EUROCAE Technical Work Programme (TWP). This programme captures the scope of EUROCAE work into 9 Domains (e.g. on-board avionics) and undertakes to foresee the development in each Domain to capture possible future work for EUROCAE (roughly five years in advance). The TWP is approved by the Council and then provides the basis for future work, especially guiding which new WGs need to be created.


Why does EUROCAE afford something like a TAC? Standardisation would work as well with able Working Groups alone.

TAC is quite a unique establishment. At EUROCAE, the technical expertise of its various aeronautical industry stakeholders is bundled in TAC, as a delegation from the Council. This has its merits, as TAC ensures from the outset that prospective work is aligned with EUROCAE member interests. An additional benefit is having representatives of key European aeronautical organisations in TAC (e.g. SJU, EASA, EUROCONTROL) to align work with SES-development in Europe. Via the General Secretariat and direct contact with RTCA, the transatlantic alignment of work can be assured as well. Close coordination between General Secretariat, TAC and Council leads to an efficient and well balanced operation of the organisation.

In a nutshell, the strength of TAC for EUROCAE is to focus standardisation work towards the interests and usefulness for its stakeholders, in coordination with external forces and regulatory bodies. Above that, a high quality level of output is assured by thorough discussion in TAC and finding resolutions in consensus.


First of all, TAC will continue providing its service to the Council and support to the General Secretariat.

Meanwhile, TAC is also focussed on all active EUROCAE Working Groups so as to maintain their efforts in line with the EUROCAE overall work programme.

Hence, contact with the Working Groups has been recognised as an important aspect. TAC relys on the reports of the Technical Secretariat that closely monitors the progress of WGs. In order to establish a more direct and also personal contact with the WGs, we plan to involve the WG chairs more directly in TAC meetings (by teleconference or direct participation) and TAC chairs will participate in the annual Chairperson Club meeting.

Also, in the framework of the Council Efficiency Initiative, the time to set up new Working Groups shall be shortened. In addition, for a WG approved by Council, the TAC will get more autonomy to set the direction of work progress. We look forward to working closely with our WGs and sharing in the discussions.
