AIM - RAC 3. 10 - Intermediate stops

Intermediate stops may not be included in a single IFR flight plan. Except for
transborder flights, a single VFR flight plan or an IFR or VFR flight itinerary
including one or more intermediate stops en route may be filed provided:

(a) for VFR flight plans, the stop will be of short duration (for purposes such as
boarding passengers, and refuelling);

(b) for IFR flight itineraries, the stop will be in uncontrolled airspace; and

(c) each intermediate stop is indicated by repeating the name of the stopping point
and its duration in the route section of the flight plan/itinerary. Record the
duration of the stopover in hours and minutes with four consecutive digits.
Example: CYXU 0045 CYXU. You may include a phone number for the
stopover in the “Remark” section of the flight plan or flight itinerary, if
available, as this may be useful in case of search and rescue.

Transborder Canada / U.S.A. flight plans shall be filed to the customs point of entry
only to avoid unnecessary alerting service procedures from being initiated due to
delays created in the process of clearing customs. Flight plans for locations beyond the
customs point of entry may be filed with an FAA Flight Service Station.
When intermediate stops are planned, the “Estimated Elapsed Time” must be
calculated as the total time to the final destination, including the duration of the
intermediate stop(s). It should be noted that Search and Rescue (SAR) action would
only be initiated at the specified SAR time or, in the event that a SAR time is not
indicated, 60 minutes for a flight plan and 24 hours for a flight itinerary after the ETA
at the final destination. Pilots wishing SAR action based on every leg of a flight should
file one flight plan or flight itinerary for each stop.
