yellowknife water AEROdrome (Cen9)
Back Bay and East Bay in Yellowknife comprise the CEN9 licensed water aerodrome. The waterdrome is subject to air traffic control by NavCanada but the tower does not have visual on either bay. Pilots must advise the CYZF tower prior to operations on Back Bay or East Bay.
The strobe light on Pilot's Monument must be activated to alert boats when aircraft are arriving or departing the waterdrome. The strobe is activated by depressing mic 5 times on 119.5 at 2 miles final or 45 seconds prior to takeoff. Pilots should be aware that the strobe is notoriously finicky and may not always respond to activation attempts.
The YZF tower will provide wind direction at the airport. Wind direction may vary a bit on Back Bay and East Bay, so pilots should assess water and wind conditions on approach and advise the tower of intended take-off or approach and landing direction. Upon landing on either bay, pilots must report down and clear.
