121 Supplemental Duty/Rest
Does anyone have or know where to obtain a good algorithm for 121 Supplemental flight time/rest requirements? The type that helps you figure out if your crew is legal for a trip. Trying to make one and need a benchmark to compare, perhaps improve upon. Thanks.

Basic Crews or Heavy Crews?
or try FAR 121.5xx

121 subpart S does not seperate domestic and international, however, it does extend flight times for "international/overseas" operations. You have "duty" time limits depending on how many pilots/FEs are operating the trip.

(d) If a flight crewmember is required to engage in deadhead transportation for more than four hours before beginning flight duty, one half of the time spent in deadhead transportation must be treated as duty time for the purpose of complying with duty time limitations, unless he is given at least 10 hours of rest on the ground before being assigned to flight duty.
(e) Each certificate holder conducting supplemental operations shall give each airman, upon return to his operations base from any flight or series of flights, a rest period that is at least twice the total number of hours he was aloft as a flight crewmember since the last rest period at his base, before assigning him to any further duty.

Now with all that said............
The question is:
When you are flying international, do you, as an airman, still have to have to abide by paragraphs 505b, 507b or 509b?
I don't see anything that waives or overrides those paragraphs.
If anyone can find something that does, please post it!

121 supp.
As I understand it...
International basic crew in 747-200 (2 pilots & 1 engineer) under the FAR's there is absolutely no published FAR duty limitation. If you camp out, waiting for a maintenance delay at a tech. stop and have 10 more hours to fly your are still good to go as long as you are under the scheduled 12hrs flight in 24 consecutive hour limitation. So, the finalduty limit is the 1 in 7.
If you go from basic crew to heavy/double and back you are limited to basic crew rules, 121.525c. Here is the test for that...Been scheduled in a basic crew more than 20 hours in the past 30 days? OR Had basic crew interrupted by heavy crew in the past 30 days? Then...limited to basic crew rules 121.525c.
Now you see why I am building a flow chart. After 24 hours it is too hard to think in these terms at work.
