C9 Duty Max Calculator

You must convert your report time for the duty period in question to HDT (Home Domicile Time) and enter it. The calculator will not do this for you!

Report Time is the time you started your duty day and MUST be converted to your Home Domicile Time before entering. This determines not only when you started, but which actual duty max is used in the calculation. 

Answer "yes" to High Value Trip (HVT) if all are true: 

• single duty period pairing (regardless of calendar days

• report time of 0500 -1859

• has 3 or fewer segments

• 9 hours flight time or more. 

Clearing customs at the beginning and/or end of your duty period adds :15 minutes to your duty day. This field will factor that into the calculation for each customs clearance. 

Clearing customs in the middle of your pairing  does not extend your duty day and should not be included when filling this field (ie for a Toronto turn with a long sit requiring you clear immigration/customs on the sit you would not enter it).

Our duty max is based on the originally published flight times - not the updated times, regardless of how the jet stream may be affecting flight times on this particular day. Therefore, we MUST get our flight time for this field from the Scheduled pairing information and NOT from the updated pairing info. 

Check the upper left corner of the pairing info to ensure "scheduled" is in bold black and you are entering the correct info (see pic above).

As an example, if you are on a DEN pairing, then Mountain Time is your HDT. If your final segment for this duty period is departing out of LGA, then you would select HDT +2 (Home Domicile Time + 2) since LGA is in Eastern Time and is 2 hours ahead of DEN). You can use Google to verify time zones if needed. 

This is your Latest Legal Door Closure. One minute later and you are illegal for this flight. You may be required to remain on board with passengers and/or you may be reassigned to a shorter flight which will have you landing within your duty max. Go to the AFA IRROPs Survival Guide for next steps.
