I submitted a question on the "Charter" forum, but I think I should have maybe posted it here.

Where can I find any rules/guidance pertaining to the seating requirements when a 3rd pilot is required onboard due to flight time. I haven't had much luck looking through the FARs, maybe one of ya'll could point me in the right direction.

Thanks folks

Sec. 135.269
(5) Adequate sleeping facilities on the aircraft for the relief pilot;

Now, that is some grey area there. lol

Google FAA AC 121-31 from 1994, for description of crew rest facility in flight. There may also be a FAR 25 AC on acceptable means of compliance. Google it and train loads of info.

that ac is for 121, anyone have any guidance for 135? the potty seat is good enough for us

Doesn't the AC only kick in under FAR 121 ops that are more than 12 hours aloft? Some of our freighters don't have a bunk and are limited to 12 hours aloft.

121.485 and 121.523 specify that adequate sleeping facilities are only required when a pilot is scheduled for more than 12 hours of flying.

On the other hand, 135.269 allows a max of 12 hours aloft for a three-pilot crew, yet specifically requires adequate sleeping facilities for any crew of three or four pilots.
