New Flight Approach to Be Tested at Trail Airport After Previous Procedure Loses Authorization
Why It MattersThe case shows how regulatory shifts can strand existing approach procedures at smaller airports, forcing operators and consultants into a deviation-approval process before poor-weather reliability is restored.
What happened
Trail Airport will test a new flight approach procedure next month after its previous approach lost authorization under new Transport Canada rules. Airport manager Enrico Moehrle told city council this week that consultant JetPro will seek a Transport Canada "criteria deviation" approval following the flight checks scheduled for next month.
JetPro had originally aimed to reinstate the previous straight-in approach, which Moehrle described as crucial for Pacific Coastal Airlines operations and medevac flights. Moehrle noted that while the airport has other approach options, the straight-in procedure was considered more reliable in poor weather conditions.
JetPro has also completed a separate new circling procedure that follows the contours of the surrounding valley. That procedure is already fully compliant with regulations and will be submitted to federal authorities for approval after next month's tests.
Industry impact & what to watch
This case illustrates how a rule change at the regulator can invalidate an approach procedure an airport and its carriers had relied on, even when no physical or operational change occurred at the airport itself. Smaller regional airports that depend on a single reliable approach for weather-constrained operations, including medevac flights, are particularly exposed when such procedures lapse.
Approach design and certification work of this kind typically runs through two tracks at once: the deviation request needed to keep a previously used procedure alive, and parallel development of a fully compliant alternative, here the valley-contour circling procedure. Running both tracks lets an airport avoid being left with no viable low-weather option while the deviation is assessed.
The next milestone is the flight check scheduled for next month, whose results will determine whether Transport Canada grants the criteria deviation for the straight-in approach and whether the circling procedure moves into formal federal approval.
