    Buttonville's Safety Manager would like our assistance in keeping track of issues that should be reported as CADORS or simply things that can be managed better on the field.  If you experience this type of situation, please write it up (using the form below).  You can do this whether or not you submit a separate CADORS.

    Wednesday’s club meeting featured members Mark Brooks, David Cox, and Phil Lightstone, discussing recommended procedures for flying into and out of the Buttonville mandatory frequency area.

    Please review the excellent slides from the meeting presentation:


    Please also review this document discussing recommented VFR procedures at Buttonville. An equivalent IFR document is in progress.

    Now that the tower has closed, Buttonville is a Mandatory Frequency area.  Our president has collected a series of useful links, which are summarized here and will be maintained in the future on the Useful Links page.

    The Smart Pilot Video series is also useful for some reminder information on process in Mandatory Frequency areas:

    AeroWeather Pro (IPhone/pad app) has the LWIS for Buttonville now. You may have to pay a bit extra ($5/year subscription) plus upgrade to PRO but it is useful. You access it through the settings page in AW Pro and additional features (plus subscription).

    The Commanding Officer of the Markham Cadet Flying Site asks that we make our members aware of the following information, to reduce potential conflicts in the vicinity of Buttonville, Markham, and the Claremont practice area:

    Operating near Claremont, Markham or Buttonville?

    The Air Cadet League of Canada operates 8 Gliding Centres from various small airports across Ontario each Spring and Fall.  The Markham Cadet Flying Site (Markham CFS) operates from Markham Airport (6.5NM NE of Buttonville) and would like to make you aware of our presence.  A recent review has identified traffic conflicts occurring at an increasing rate. The most alarming were aircraft that blundered through the circuit area, unannounced, at circuit altitude operating to/from Buttonville or the Claremont Training Area.

    Quick Facts

    • Markham CFS operates from April through mid-June and late August through mid-November
    • Operations occur only on:
      • Weekends and holidays during Day VFR between 0800 and sunset, and
      • Occasional Friday afternoons during Day VFR until sunset
    • All active operations are advertised by NOTAM and are included in the Buttonville ATIS
    • The tow aircraft and up to 2 gliders will only be found in the red box bounded by:
      • Markham airport runway 09/27 centre line and the town of Stouffville
      • McCowan Road and 10th Line
    • All operations are conducted from the surface to 3,500’ ASL
    • Glider and tow aircraft continuously monitor and transmit on VHF 122.8
    • The tow aircraft uses TCAS technology and will detect aircraft operating a transponder
    • Markham Unicom or “Glider Ground” will provide GTGC operational status on VHF 122.8
    • During active operations, the tow aircraft and gliders remain in the north circuit–all other powered traffic remains in the southern circuit.  Circuit joining via overhead is not authorized.
    • Markham is a PPR (Prior Permission Required) airport. Permission must be obtained from the airport operator by phone as per the CFS.

    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.


    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.

    As a refresher, please review the Transport Canada one-page pdfs on uncontrolled airspace operations:

    VFR Communications Procedures at Uncontrolled Aerodromes With MF and ATF Areas
