Logan-Cache Airport (KLGU) is a busy general-aviation field in Cache Valley, three miles northwest of Logan, Utah, home to Utah State University's flight training programme and the LE Aviation FBO. With a 9,000-foot main runway equipped for instrument approaches, it is Utah's second-busiest airport by aircraft movements and a practical destination for VFR and IFR training flights alike.
Logan-Cache Airport lies in Cache Valley in northern Utah and serves as the general-aviation gateway for the Logan area and southeastern Idaho. It is owned by the Logan-Cache Airport Authority, a joint body formed by Cache County and Logan City, and its facilities are used heavily by Utah State University's fixed-wing and rotorcraft aviation programmes as well as by LE Aviation (Leading Edge Aviation), which runs flight training, FBO services and a pilot supply shop on the field. With a long, lit runway and high volume of light-aircraft training traffic, it offers a sim pilot a realistic mountain-valley general-aviation environment with genuine instrument approach capability.
The airport sits in Cache County, Utah, about three miles northwest of the city of Logan, within the Cache Valley. Despite its size and traffic volume it remains an uncontrolled, Class G airport, with Class E airspace beginning at 700 feet above ground level overhead. Two former control towers on the field are non-operational, underlining its status as an uncontrolled aerodrome.
Logan-Cache has two physical runways. The primary runway, 17/35, is 9,006 feet long with a hard surface, lit, and equipped with an ILS on runway 17. The secondary runway, 10/28, is 4,067 feet long with a hard surface. Field elevation is 4,449 feet.
Pilots can obtain weather from the ASOS on 135.275 MHz. Flight service (Cedar City Radio) can be reached on 122.2 MHz. The common traffic advisory frequency and UNICOM is 122.8 MHz, used for self-announced traffic calls at this uncontrolled field. An ILS approach is available to runway 17.
As an uncontrolled Class G aerodrome, traffic is coordinated by pilots self-announcing on the 122.8 MHz CTAF/UNICOM frequency rather than through a control tower; the two control towers on the airport are no longer operational. Pilots should expect a mix of general-aviation training traffic from Utah State University's flight programme and scheduled cargo contract flights operated by Ameriflight and Gem Air for UPS and FedEx.
The airport is located roughly three miles northwest of Logan within the Cache Valley, bordered by the surrounding mountain terrain typical of the area; pilots approaching from the south or east will use the city of Logan and the valley floor as the principal visual references before joining for the long asphalt runway 17/35.
Logan-Cache Airport has a long history of scheduled air service: Western Airlines flew from Logan between 1946 and 1959, when West Coast Airlines took over the route until withdrawing in 1964. Key Airlines then served the field from Salt Lake City from 1964 to 1976. In 1976 the Utah carrier Transwestern Airlines based its headquarters at the airport, operating flights to its Salt Lake City hub until its acquisition by Horizon Air in December 1983. The airport was originally owned by Cache County before ownership passed in 1992 to the Logan-Cache Airport Authority, an inter-local agreement body between Cache County and Logan City. Several notable incidents have occurred at the field, including a 2005 landing accident involving a Grumman Gulfstream II with no fatalities, and two fatal Utah State University training accidents, in 2016 and 2022.
Today Logan-Cache is a general-aviation airport handling over 100,000 aircraft movements a year, making it the second-busiest airport in Utah by that measure. Scheduled activity now consists of contract cargo flights operated by Ameriflight and Gem Air on behalf of UPS and FedEx Express, along with frequent charter flights supporting Utah State University athletics. Utah State University operates a substantial aviation campus at the field, including fixed-wing and rotorcraft flight training, classrooms and a flight simulator room. LE Aviation operates as the field's FBO, providing avgas and jet fuel, hangar and tie-down space, oxygen service, ground power unit support, lavatory service, aircraft detailing and 24-hour call-out availability, together with a pilot lounge, flight-planning area and a courtesy car for visiting pilots.
