The Advisory Committee agrees with the Commission that, for the purpose of assessing the present operation, the definitions of the relevant product markets are: a) The markets for alternating current (AC) generation systems within electrical systems (i) AC generation systems market can be segmented respectively into constant and variable frequency, even though the relevance of further segmenting the market can be left open for the purpose of this case. (ii) the question whether generators for different aircraft platform sizes should be defined as a distinct product market also can be left open for the purpose of this case. (iii) the question of further segmenting the market for power generation according to commercial and military applications can be left open for the purpose of this case. b) The markets for respectively primary and secondary distribution systems within AC distribution, low-voltage and high voltage direct current (DC) distribution; c) The market for aircraft engines, even though the question whether the market should be narrowly defined on the basis of the mission profiles, or whether it should be considered a unique market including both turbofan and turboprop engines can be left open for the purpose of this case; d) The markets for Auxiliary Power Units (APUs) for respectively large commercial aircraft and for regional jet aircraft, even though the relevance of a further segmentation according to power output or performance criteria can be left open for the purpose of this case; e) The markets for respectively electronic engine controls (‘EECs’), main fuel pumps, and fuel metering units (‘FMUs’) (together referred to as ‘engine controls’), even though the relevance of a further segmentation according to the size of the engine and the purpose of the aircraft can be left open for the purpose of this case; f) The markets for fuel nozzles, even though the question whether the market should be further segmented depending on the size and/or type of the engine can be left open for the purpose of this case; g) The markets for flight control actuation systems, even though the question whether the market should be further segmented as primary flight control actuators (‘PFCAs’), secondary flight control actuators (‘SFCAs’), trimmable horizontal stabilizer actuators (‘THSAs’), rotorcraft flight control actuators (‘RFCAs’) and missile actuators can be left open for the purpose of this case; h) The market for mechanical sub-assemblies specifically produced for THSA systems, even though the question whether this market should include the supply of stand-alone ball screws for THSA systems can be left open for the purpose of this case; i) The market for nacelle systems, even though the exact product market definition can be left open for the purpose of this case; j) The market for ice detection systems, even though the exact product market definition can be left open for the purpose of this case; k) The market for pressure transducers, even though the exact product market definition can be left open for the purpose of this case; l) The market for lighting, even though the exact product market definition can be left open for the purpose of this case; m) The market for helicopters, even though the exact product market definition (distinct product markets for military helicopters and civil helicopters) can be left open for the purpose of this case; n) The market for helicopter rescue hoists, even though the exact product market definition can be left open for the purpose of this case; o) The market for air data probes, even though the exact product market definition can be left open for the purpose of this case; p) The markets for component MRO services, even though the exact product market definition can be left open for the purpose of this case; q) The markets for spare parts and inputs related to the provision of MRO services, even though the exact product market definition can be left open for the purpose of this case.
