Can’t find it now but I do recall seeing it. I see them at work and maintenance of ELA is mandatory for airliners.
The only downside I see is that you have to buy these standards, unlike the FAA publications which you can just download over the internet. When I looked into the c2490 of working up an Electrical Load Analysis for the FormI found nothing in the legacy Part 23 or Advisory Circular guidance that outlined the requirements.
A summary can then be used to relate the ELA to the system capacity and can establish the adequacy of the power sources under normal, abnormal, and emergency conditions.
I personally cannot make any sense of it.
The video is under a picture of Michael Huerta with a small red link marked ” Video” almost at t2490 end of r2490 article. When possible, the basic format of the original ELA should be followed to ensure consistency in the methodology and approach. The FAA defines a light sport aircraft as an aircraft, other than a helicopter or Powered-Lift that, since its original certification, has continued to meet the following: This is achieved by evaluating the average demand and maximum demands under all applicable flight conditions.
Norma ASTM F()
Note 1 — The ELA should be maintained throughout the asrm of the aircraft to record changes to the electrical system, which may add or remove electrical loads to the system. The significance for zstm, is that a light sport aircraft can be flown by a pilot using just a drivers license as a substitute for a medical certificate, instead of having to get a third class medical. Speed in Level Flight at sea level at standard temperature: The Eng-Tips staff will check this out and take appropriate action.
These new specs whilst useful to the Experimental aircraft movement, are not aimed specifically at them.
But like all FAA activities there is always another shoe. Some maybe-useful MIL-data, this subject Today, some 12, ASTM standards are used around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence.

I will understand perfectly if you just red flag it. Historical Version s – view previous versions of standard. I did a little bit of work on the Tiger that Lopresti did the speed mods and the better looking cowling on. There is more going on in the industry though, although I don’t know how or when it will unfold. You are judged not by what you know, but by what you can do.
Link to Active This link will always route to the current Active version of the standard.
ASTM F2490 – 05(2013)
Not sure how much traction they are getting at this point, but there was f249 Notice in the Federal Register a couple months ago about setting up a working group. Are you an Engineering professional?
Make from it what you will. The specification titles lead me to believe the existing guidance is or may soon be obsolete. Where I have been working to the existing guidance which does seem adequate I’d like to find out more about what’s headed our way. No items in cart.
