Tracking Flight Time Limits and Rest Requirements: FAR 117

This section builds on the material discussed in the previous section, Tracking Flight Time Limits and Rest Requirements: FAR 121, FAR 135, and Transport Canada. Please make sure you understand the previous section before reading this section.

Keep in mind that for FAR 117 tracking it is especially important to enter the correct number of scheduled pilots for each flight schedule.

Additional Duty Time Types for FAR 117 Requirements

In the previous section, we entered all schedules as type Flight Schedule, Duty Schedule, or Deadhead. We use these schedule types for FAR 117 tracking as well, but we also introduce two additional duty types:

Rest Within Duty

If you are provided with a rest period during your duty period, enter this time as Rest Within Duty. Note that rest within a duty period can be either on the ground, or in the air.

Short Call Reserve

For any time spent on short call reserve, enter an operational record of type Short Call Reserve.

Augmented Crew

If you are scheduled to fly with a flight crew size larger than the minimum required, check the "Augmented" checkbox when entering the corresponding flight schedule.


In the previous section, you set up your home airport code under Contact Details. Your home airport code is part of what goes into an "acclimation" calculation.

For each flight and duty schedule you enter, ZuluLog will use the start point and end point to determine where you are (i.e. your "theater" in FAA-speak). Once you have spent sufficient time in any one place, you are then "acclimated" to that theater. Of course, ZuluLog performs all these calculations for you—all you need to do is enter accurate flight and duty schedules.

FAR 117 also imposes certain conditions when you spend enough time away from your home base. ZuluLog takes care of these calculations for you—the important thing to remember here is to enter your home base airport consistently under your Contact Details, your flight schedules, and your duty schedules. For example, if you've set up your home airport as KJFK, make sure to enter KJFK rather than JFK in all flight and duty schedules. If you use JFK across the board instead, that's ok too—you just need to be consistent.

Checking Your Compliance

This works the same way as before—go to Currency/Schedules -> Flight/Duty Time Compliance. Select "FAA 117 - Part 121 Passenger Operations" from the drop-down, and click Calculate.

The system will perform all relevant calculations for you, and display the results in a table. For each applicable section and paragraph within FAR 117, you'll see a list of messages, for any concerns or violations found. As always, no news is good news—if you don't see any messages listed against a paragraph, your schedules are compliant.

As before, the system will look at all flight and duty schedules in the future, and all flight and duty schedules up to one year in the past, when calculating compliance.

Also, because of the way the language of FAR 117 is structured, you may not see table rows for all chapters. For example, FAR 117.15 (Split duty) is not represented as a separate row in the result table, because its calculations affect other rows when appropriate, by removing a valid split duty period from other calculations. Rest assured that your compliance with FAR 117 regulations is being calculated, and any concerns are being reported to you.

Creating Flight Entries From Schedules

As before, once your scheduled landing time has passed, you can pull up a flight schedule entry, enter the actual flight time, and click Create Flight Record to generate a flight entry in your pilot logbook. You can then edit the new flight entry to fill in additional details such as instrument approaches, remarks, etc.
