DescriptionThis airport was actually called the Avon STOLport.
The airplane that was frequently used by Rocky Mountain Airways was the DeHavilland DHC-7 (Dash 7).
The contract for keeping the airport cleared was under the Nottingham family (Randy)
and they installed an underground heating system to actually help heat the ground
and make cleaning/clearing the runway easier & at times also completely unnecessary.
Rocky Mountain Airways had a local nickname of Rocky Mountain Scareways
and the descents into this airport occasionally produced a zero-G sensation due to the steep descents
(I have flown into that airport at least 4 times & it was better than any roller coaster ride I’ve ever been on with steep banks & rapid descents).
Missed approaches were not a big deal because the valley descends & widens very quickly 'down valley' to the west.” According to former Rocky Mountain Airways pilot Lou Popolizio,
the 11/2/79 Avon MLS Rwy 28 Approach plate indicated Avon Airport was located at an 7,538' elevation.
Rick reported, “The MLS approach had a Decision Height of 8,644' MSL.
The distance from the final approach fix (SCALI intersection) to the end of the Runway 28 was 8.7 NM & the glideslope intercept began at 15,000' MSL.
You had to descend 7,468' in 8.7 NM which is an 8 degree glideslope.
This descent amounted to an altitude loss of 858' / NM.
We typically had an approach speed of 77 KIAS which is approximately 90 KTAS.
We typically saw 1,000-1,400 FPM descents on the glideslope.” The above description has been prepared by IPACS forum user JetJockey10.
