RWY 33

Bert Mooney Airport sits in Butte, Montana at 5,550.5 ft MSL. It has two asphalt runways. The longest is runway 15/33 at 9,000 ft. There is no control tower, so plan on CTAF 123.0 for local traffic and UNICOM 123.0 for field services. The airport has one ILS approach to runway 15. Pattern altitude is not published in the facts. Use the standard 1,000 ft AGL for light piston traffic unless the current FAA Chart Supplement says otherwise.

Butte Aviation is on the field. It carries 100LL, Jet A and Jet A Prist. If you are bringing a larger aircraft, note the published restriction on taxiway D for wingspans under 100 ft unless you have prior permission. The field also has cold weather notes. Altitude correction is required at or below minus 24 C. Snow removal can be active during snowy periods. Deer are also reported in the airport area.

Terrain matters here. Runway 33 has a VASI that should not be used beyond 1.5 NM because of high terrain. Runway 30 has a PAPI that is limited to 2.1 NM from the threshold. The PAPI on runway 12 is also restricted to the right of centerline. Check the current FAA Chart Supplement before departure for any operational changes, especially if you are flying a commercial aircraft or anything over 9,000 lb.

Frequently asked questions

What is the field elevation at KBTM?
KBTM sits at 5,550.5 ft MSL. That elevation matters for takeoff performance and winter density altitude planning.
What is the pattern altitude at Bert Mooney Airport?
The facts do not publish a pattern altitude. Use the standard 1,000 ft AGL for light piston traffic unless the current FAA Chart Supplement says otherwise.
Does KBTM have an ILS approach?
Yes. KBTM has one ILS approach to runway 15. Check the current FAA Chart Supplement for the latest approach details before you fly it.
Is Bert Mooney Airport towered?
No. KBTM has no control tower. Use CTAF 123.0 for traffic calls and UNICOM 123.0 for field coordination.
What is the longest runway at KBTM?
The longest runway is 15/33 at 9,000 ft asphalt. That is the main runway to plan around for heavier aircraft and winter performance.
Which FBO is on the field at KBTM?
Butte Aviation is on the field. It carries 100LL, Jet A and Jet A Prist. Call (406) 494-6694 for current service details.
Are there terrain or lighting issues at KBTM?
Yes. Runway 33 has a VASI that should not be used beyond 1.5 NM because of high terrain. Runway 30 has a PAPI limited to 2.1 NM from the threshold. The runway 12 PAPI is unusable beyond 5 degrees right of centerline.
Are there any special operating notes for KBTM in winter?
Yes. This is a cold temperature airport. Altitude correction is required at or below minus 24 C. Snow removal operations can be in progress during periods of snow, so expect changing surface conditions.
