A private jet crew's experience can appear different on paper depending on the regulatory body they flew under. Two first officers with identical careers, including the same aircraft, years, and routes, can have different logbook entries. One trained under the Federal Aviation Administration, while the other was under the European Union Aviation Safety Agency.

The difference lies in the pilot-in-command time, with one logbook showing 1,500 hours and the other showing 0. This discrepancy is not an error, but rather a result of different regulatory definitions.

Further details on this discrepancy and its implications are available from Paramount Business Jets.
