It’s a super confusing formula used to limit you to a rolling credit of 90. Each month it looks back of your last 8 months credit then uses 82 (i think it’s 82) as the credit for the 9th month and adds them together then takes an average. Whatever that number comes out to be is your “imax”.

Basically you can credit a lot for 8 months then the 9th month you’re “imaxed” and only have to fly what your limit is. You then get paid the minimum line construction value while only having to work up to your imax. So you could work zero days and still get full pay. If you drove your imax low enough you would only have to fly a portion of the following month as well.

I probably explained that really bad but it’s a good deal if you can get it to work for you. Lots of guys don’t mess with it.
