Official FAA learning statement

Recall regulations - intermediate airport authorizations

What this means for your checkride

In domestic operations, an airplane that lands at an intermediate airport specified in the original dispatch release and remains there for not more than one hour may continue without a new specific dispatch authorization. In flag operations, no person may continue a flight from an intermediate airport without redispatch if the airplane has been on the ground more than six hours. These rules govern when a new authorization is needed after a stop en route.

Crews must know the time limits that determine whether a flight may continue from an intermediate airport without new authorization or redispatch.

Where to study it

Before your checkride (14 CFR 61.39)

A code on your test report is an area of deficiency. An authorized instructor must review it with you and endorse that review before you take the practical test, and the examiner may revisit it during the oral. Study it until you can explain it out loud, not just recognize the answer.
