I am working on an MSc. thesis project about the electrification of aircraft. Since the rule of thumb is to design the generators for the worst case scenario, I would like to include as much information as possible in my simulation.

I was wondering the power consumption of the Electronic Flight Instrument System (EFIS) and In Flight Entertainment systems (IFE). In addition to that I also need information about the the heat dissipated from those systems, so that the cooling power needed for those units can be compensated through the Environmental Control System (ECS).

I tried to find the above mentioned values, but they are not publicly available, or need to be purchased through SAE circulars. I'm looking for information for both airliners and military aircraft.

    $\begingroup$ It's remarkable that these days, the base research of a Masters is done ........ on an internet QA site. $\endgroup$ – Fattie May 4 '18 at 11:52
  • $\begingroup$ @dalearn What I am looking for is as stated above, the heat dissipation info of any EFIS and IFE system (I'm aware military jets don't have IFEs) To be more precise; I am following the ratios of power consumptions used in this journal: journals.sagepub.com/doi/pdf/10.1177/0954410014534638 (page 448 & page 460) However, the power needed for cooling of a typical IFE/EFIS system (radiated heat from LCD screens/or any other electronics) is not included in this paper, so iterating including the ECS for an almost real-life simulation is not possible for now. Hope this clarifies a bit. $\endgroup$ – MustafaYildiz May 4 '18 at 12:13

  • $\begingroup$ The best data is the a/c design drawings, but it's not generally available as it's considered proprietary by most of the manufacturers. There are guidelines from SAE and ARINC, but they're just that, guidelines. Specific a/c systems guides can give you some reasonable numbers if you are reasonably good at reverse engineering. A good source - though not complete - of these documents is SmartCockpit. The numbers do change. OEMs constantly push suppliers to reduce size, weight, and power needs of their equipment. $\endgroup$ – Gerry May 4 '18 at 22:46
