Drone photography in Dalhousie, Alberta

Dalhousie answers to two pieces of airspace at once — the CYYC control zone measured at about 10 km, and the Alberta Children's Hospital heliport operating about 3 km away. An operator who plans against the airport alone can put a flight path across a hospital helicopter approach without knowing it, and that is the kind of error that ends a shoot on site.

Both constraints are plotted before booking: the NAV CANADA authorisation covers the control zone, the flight plan keeps clear of the heliport approaches, and the work is delivered in the standard turnaround.

Airspace. Dalhousie lies inside the charted CYYC control zone, about 10 km from Calgary International. Work here flies under an Advanced RPAS certificate, and the NAV CANADA RPAS authorisation is in hand before a shoot date is confirmed. Alberta Children's Hospital heliport operates about 3 km away, and flight plans keep clear of its approaches. Before any flight, the exact site and altitude are checked against NAV Drone. This is a corridor-level assessment; the specific address is confirmed against NAV Drone before every flight.

Terrain. A mature plateau community on the shoulder of the northwest hills, with Nose Hill Park rising to the east and the ground falling south toward the valley communities.

Wind. Chinook belt. West wind crosses the community's open upper streets at strength, and Nose Hill to the east does nothing to slow a westerly.

Light. Mature tree canopy means the community reads greenest in full summer; in winter, low sun and bare trees open up sightlines that the canopy hides in July.

On the ground. Launching and landing in City of Calgary parks and on pathways is restricted by parks bylaws, so Dalhousie flights are staged from private property with the client's consent. About 20 minutes from the base. Same-day scheduling is realistic, and Hawkwood, Silver Springs or Varsity can be shot on the same trip.
