Domestic flight time limitation...30 hrs max in any 7 day period

Wayst

§ 121.471 Flight time limitations and rest requirements: All flight crewmembers.
(a) No certificate holder conducting domestic operations may schedule any flight crewmember and no flight crewmember may accept an assignment for flight time in scheduled air transportation or in other commercial flying if that crewmember's total flight time in all commercial flying will exceed -

(1) 1,000 hours in any calendar year;

(2) 100 hours in any calendar month;

(3) 30 hours in any 7 consecutive days;

(4) 8 hours between required rest periods.





You can't fly more than 60 hours in a two week period. This is why the ACMI companies have a much lower min guarantee because you are working two weeks a month (potential 60 hours) instead of pax companies where you work 4 weeks a month (potential 100 hours).

It's not three separate certificates, it's three authorizations in OpSpec A001.

Note: yes, AAWH actually *does* currently operate three certificates, but that has nothing to do with this. Atlas, Polar, and Southern each have similar authorization language in A001: Domestic, Flag, and Supplemental.

It is up to the certificate holder to determine which authorization should be used for a particular flight, in accordance with all applicable limitations and authorizations in the OpSpecs and regulations.

This is all transparent to the flight crew. Our procedures and policies in the flight deck are identical for all three operations.

Most of the burden is on crew scheduling and their software (AIMS), to determine our required rest and legalities for each of the various operations (also gotta throw 117 into that mix, if operating a pax flight). The robust programming of AIMS is the biggest reason why the FAA allows us to operate this way.

Seems sketchy at first, but you get used to it. Stockholm syndrome and all that, ha!

Most ACMI carriers are supplemental.

Supplemental carriers operate under 121.500 time and duty.

121.471 is for DOMESTIC carriers. Only applies if your carrier has domestic carrier in the op specs.

Might want to look up the deference between Supplemental and Domestic carriers.

Agree with your whole post, and just wanted to add a note about the quoted portion. (my emphasis added)

There is only one FAA air carrier that is authorized to 'mix and match' 117 rest rules with 121 rest rules: Atlas. As far as I know, no other ACMI is authorized to use 117 some time, and 121 the rest of the time (including, notably, not Polar, or Southern).

117 rest rules must be fully complied with when operating a pax aircraft (whether or not there are actual pax onboard). All other Atlas aircraft may be operated under the applicable 121 rest rules (Domestic, Flag, or Supplemental).

Except for domestic day or
Base Trip Lines, which are full of them.

According to Carlson at the court case in D.C., there are two operators who have that authorization: Atlas and ATI (believe it or not). I believe that's due to the 757 combis that ATI operates. Obviously, their operation is not a very close resemblance to ours.

Just a point of order that the fuel reserves and alternate requirements are still different. One of the memos that came out said the releases would start showing what rules the flight is operating under next year.

If it is done right you can also do 350/90 days.

That sounds like a hoot! Sorry but my goal is to retire the lowest time airline pilot in history.
