Frequently asked questions
Is fuel available at Thayer Memorial (42M)?
Thayer Memorial does not list confirmed fuel types in current records. The field is unattended (UNATNDD), so any fuel arrangement would need to be confirmed directly with airport management before a flight. Dispatchers should plan for the possibility of no on-field fuel and identify an alternate within range. West Plains Regional, about 27 nm away, is one nearby option worth checking.
What runway lighting is available at 42M?
Runway 09/27 at Thayer Memorial has non-standard low intensity runway lights (LIRL), activated by keying the CTAF frequency 122.9 five times. Edge and threshold lights are placed 15 feet off the actual pavement edges rather than the standard offset. Pilots operating at night should account for this non-standard lighting placement when assessing runway width visually.
How is customs handled for arrivals near Thayer Memorial Airport?
Thayer Memorial (42M) has no onsite customs processing. The nearest customs facility is at KSGF, located about 97 nm away. Flights requiring customs clearance need to route through KSGF or another designated port of entry rather than clearing directly at Thayer Memorial.
What obstacles should pilots be aware of near the runway at KThayer Memorial?
Thayer Memorial's runway 09/27 has multiple close-in obstructions on both ends, including brush up to 15 feet high near the runway end and ground rises close to the pavement. Runway 27 additionally has fencing and brush ranging from 1 to 21 feet within 65-80 feet of the runway end. Wildlife is also reported on the runway during early and late hours, an added consideration for approach and departure timing.
