Aerobatic operations are to be conducted per 91.303. We recommend making position reports on the closest CTAF and maintaining vigilance as transient pilots may not be aware of aerobatics in the area. The first two links below provide general guidance to non-waivered airspace northwest of the Denver Airport that do not conflict with Class B or Victor Airways.
IAC Chapter 12 has two Aerobatic Practice Area (APA) waivers in place, Fort Morgan (FMM) and Sterling (STK) for club member use. Aerobatics must be conducted in accordance with the provisions of these waivers in order to maintain this privilege. These waivers must be activated and signed per the posted instructions on file at the FBO.
Contact Duncan Koerbel if you are a first time activater. All PILOTS MUST sign the FBO registar EACH TIME they activate the waiver and use the airspace. Duncan can be reached at 720 250 8442 or Duncindevner [at] gmail.com. See website links for FMM.
Mike Forney has arranged for this waiver. This requires one phone call to open and close the box, please be sure to sign the waiver. See below for more info.
