If you would like to enforce that users have checkouts before scheduling an aircraft or boat, you will need to do the following:
1. For each aircraft/boat, go to the edit page for that resource. Check the check box labeled 'Requires checkout' and be sure to save by clicking OK. The check box is highlighted in the image below.
2. For each user, go to the Pilot/Personal page of that user's account, and add any checkouts that they have completed. The checkouts can be specified by individual aircraft or by model. See grid highlighted in red below.
3. Contact Time Sync to let them know you would like checkouts enforced for users. Currently checkouts can be enforced by model.
