Breaking News : LPV minimums approved and published for CYBW RWY 17 & 35.

After many years of joint lobbying by SABPA and the CAA,  Nav Canada has published on July 19th 2018 in Canada Air Pilot (CAP 3), and other products, new LPV minimums for RWY 17 & 35, both with Minimum Descent Altitudes (MDA) of 250’ (same as the ILS RWY35). This is a great achievement.

New LPV minimums for Rwy35 CYBW


  1. The airport is authorized for Code B aircraft, which include a wingspan of up to 74 ft, and up to a gross weight of 40,000 lbs.  Many of these aircraft cannot land here when the runway is contaminated by rain, ice or snow. A runway extension would allow this type of Code B aircraft, operated by pilots with even the basic skill levels, to come and go under virtually all climatic conditions. 
  2. A runway extension would attract more itinerant, corporate and private aircraft to the field, relieving YYC from it’s continuous pressure and allowing YBW to develop as a true “reliever” airport. 
  3. A true reliever airport, fully capable of handling all Code B aircraft, would contribute greatly to the Calgary, and indeed the Alberta air traffic infrastructure, reducing the delays, holding patterns, requirement for slot times and additional frustrations so often encountered in trying to arrive at YYC.
  4. Moreover, the lack of a suitable FBO has been identified as a hindrance to operations at YBW.  This runway extension would also allow for the development of the “critical mass” of traffic, which is obviously required to make the sizeable capital investment in a new, large FBO economically viable.  
  5. It goes without saying that an increase in this type of aircraft at YBW would benefit all of the existing businesses, also creating spin off economic benefits for the airport community, the County of Rocky View, the town of Cochrane, and the surrounding area.
