Alright,
4.C.1. Reserve Line Guarantee: The line guarantee of a reserve pilot for credit purposes will be his ALV minus two hours, but no less than 72 hours and no more than 80 hours,...
So reserve guarantee is ALV - 2 hours. But it cannot be less than 72 hours and cannot be greater than 80.
23.A.2. ―Average line valu (ALV) means a number of hours established by the Company between 72 and 84 hours (inclusive) that is the projected average of all regular line values, for a position, for a bid period.
So min ALV is 72 hours and max is 84. Reserve guarantee is not 70-82 hours but instead has it's floor and cap limits of 72-80 hours.
Looking at the ALVs in PBS for March this matches.
- ATL 330B ALV is 72 hours, RES GUAR is therefore at the min 72 hours.
- ATL 320A ALV is 84 hours (the ALV limit), the RES GUAR is therefore 80 hours or the max reserve guarantee.
- ATL 320B ALV however is 76 hours and thus the RES GUAR is 74 hours or 76 hours minus 2 hours which is 74. [/INDENT]
23.S.2.a.1): A reserve pilot will not be assigned a ration that will cause his credit to exceed the ALV plus 15 hours.
23.S.2.d.: A reserve pilot will not be required to remain on call after his accumulated credit equals or exceeds his reserve guarantee.
The best summary here is from the December Crew Planning news:
MAX RESERVE AND RESERVE FULL
Beginning with the December bid period, PWA Section 23 S.2.a.1 becomes effective. Previously, a reserve pilot would not be assigned a rotation that would cause his credit to exceed the ALV. The new language will allow a pilot with whose accumulated monthly block and credit is below the reserve guarantee to be assigned a rotation as long as it does not cause his credit to exceed the ALV plus 15 hours.
Also in the December bid period, Section 23 S.2.d. becomes effective. This states a pilot will not be required to remain on call after his accumulated credit equals or exceeds his reserve guarantee. However, Crew Scheduling will attempt to contact a pilot who is on a reserve on-call day the last day of the current bid period to advise him of an assignment to a rotation or short call if on a reserve on-call day the first day of the next bid period.
So as I see it, reserve guarantee is somewhere between 72-80 hours, if you haven't exceeded that you can be assigned a trip as long as you don't go above ALV+15.
