5.2.1 General

a. The date, times and points of takeoff and landing on the flight concerned must be verified, and there must be evidence that recording devices used for flight evidence were in the glider concerned during the flight.

5.2.2 OO presence at the event

OOs may certificate individual events (such as sealing and breaking seals, installation and removal of equipment, takeoff, timing at start and finish, landing, etc.) if they were present at the event for which certification is required, or are able to satisfy themselves either through evidence from persons who witnessed the event or from other reliable sources. Evidence from air traffic control or club flying logs may be used. Barometric pressure may be obtained from the log of a nearby meteorological office.
