It's not Navtech but the company. Because they are separate systems they don't talk directly. On the morning of the 13th planning will download a history report for all pilots and load that into PBS. That's the snapshot that we all bid around. They take another one right after the bids close on the 17th and load it to deal with any final changes.

The 7 day lockout serves a couple of purposes and one of them is to save the pilots from themselves. Because the data isn't real time if you make changes to your schedule in those last 7 days they don't reflect in PBS on the calendar screen or the carry-in results under the reasons tab. Pilot bids based off of what they see in PBS. So if PBS shows them off 29-30 and they were able to add a trip 29-30 while we bid that trip wouldn't be reflected in PBS.

This prevents them from getting a trip on the 1st. They end up on reserve. Get all ****y that "my pbs showed I was legal for a trip on the 1st" which you were before picking up that trip. And causes a lot of problems.

(And I just re-read the question and realized I kinda missed the point). The snapshot lookback data is taken initially on the 13th when PBS loads and then in the 17th right after it closes. History files are downloaded from CrewTrac and imported into PBS.

Did that answer it?
