As of Thursday July 19, the Buttonville control tower is operating between 0800 and 2000 local time (EDT/EST). This is a reduction from the previous hours (0800 – 2300). While the tower is closed, the airspace is MF uncontrolled.
The ARCAL system is now operational on 124.8 — 5 clicks to engage, 3 clicks to disengage. The timer is 30 minutes, and at this time only the maximum lighting intensity is available.
Update:
The ARCAL at the airport has been adjusted to give you 2 different intensities.
Now 3 clicks on the microphone will activate the medium lighting for both runways.
Now 7 clicks will activate the high intensity lighting for both Runways.
The original 5 clicks will no longer work.
The lights will then time out after 30 minutes.
