Logbook Apps

Digital Logbook Apps

The following apps have been reviewed by USPA staff and deemed in compliance with SIM 3-1 C logging guidance. Jumps tracked with these apps can be used when verifying licenses and ratings qualifications as well as skill requirements.

Note: Instructors, Examiners, S&TAs, or USPA Board members who are verifying logs towards license and rating qualifications must still check that the jumps were signed by another licensed skydiver, a pilot, or a USPA National or FAI Judge who witnessed the jump. Jumps to meet skill requirements must be signed by a USPA Instructor, Examiner, S&TA, or a member of the USPA Board of Directors.

This list is maintained by USPA Department of IT for informational purposes only to assist instructors, examiners, and S&TAs in their responsibility to accept digital logbooks while still complying with SIM 3-1 C. USPA does not specifically endorse any of the apps or associated products. There may be other apps that meet logging guidance that are not listed here.

How do I know what logs are acceptable?
There are many legitimate ways of logging jumps whether it be digitally, on paper, or a combination. First, make sure the jump contains data in all of the required fields listed in SIM 3-1 C. Next, decide what the jump should be used for. Jumps for license and rating qualifications—that is, to count towards total jump numbers—must be signed by another licensed skydiver, a pilot, or a USPA National or FAI Judge who witnessed the jump. Jumps to meet skill requirements—for example an accuracy jump—must be signed by a USPA Instructor, Instructor Examiner, Safety & Training Advisor, or a member of the USPA Board of Directors. Finally, check there has been no alteration of logs. If logs are digital, make sure none of the required fields can be altered after the signature is gathered. If logging was done on paper, make sure there are no marks or writing over required data. If in doubt, contact signatory and check. Printouts of jumps from manifest software programs signed by a drop zone authority are acceptable if all of the data required by SIM 3-1 C are present.
