Airspace Flying South on Front Range

We have discussed airspace when flying South along the front range at club meetings, but you may be a new member or may have missed the meeting where this was discussed. Here is information to help avoid airspace when flying South from Lookout, or Boulder!

The issue is that many commercial flights into Denver (DIA) are given the Larks Four Arrival procedure. This heads along the path of the V160 airway towards the Falcon VOR (South of DIA, East of Buckley AFB). In the lower left hand corner of the chart you can see the LARKS waypoint. Commercial jets arrive there at 14,000ft and start descending to approach altitude. Those pilots are briefing their approach at that time and since they are being guided by ATC they expect a clear path with no other traffic (i.e. they aren’t watching to avoid HGs or PGs). In the image you can see that the Class B airspace near Chatfield is between 10k and 12k. Technically you can fly above 12k and avoid airspace, but that could put you right in the path of a large, fast, airplane on the Larks Four Arrival. The airspace extends along the Western edge of Chatfield park and continues South past Roxborough Park before arcing to the SE over Castle Rock. The Airspace floor is 10k.

Good stuff,

Thanks JJ

When you are circling or on glide keep scanning the horizon for anything airbourne that appears not to be moving. That’s because it is coming straight at you. It’s best if we don’t cross a busy street that has commercial air traffic descending clean and fast. It’s good if we are aware of these flight routes and don’t dawdle there in lift.
