Pittsburgh/Butler Regional Airport (KBTP) is a general aviation field in Butler County, Pennsylvania, roughly five miles southwest of Butler itself. It offers a single hard-surfaced, lit runway with an ILS approach, making it a useful and well-equipped stop for VFR and IFR pilots operating in the wider Pittsburgh area.
Pittsburgh/Butler Regional Airport, also known locally as Butler County Airport, sits in Butler County, Pennsylvania, about five miles southwest of the town of Butler. It is a general aviation airport at an elevation of 1,234 feet, equipped with an instrument landing system on its single runway, which makes it a practical and instructionally interesting destination for both VFR and instrument-rated pilots training or flying in the Pittsburgh area.
The airport lies to the northeast of the Pittsburgh metropolitan area and is served by Pittsburgh Approach/Departure for arriving and departing traffic in the surrounding airspace, with a dedicated clearance delivery frequency also available. It occupies around 304 acres of land approximately five miles southwest of the town of Butler, Pennsylvania.
The airport has a single physical runway, 08/26, 4,750 feet long with a hard surface. Both ends are lit, and runway 08 is equipped with an ILS approach, giving the field a genuine instrument capability despite its general aviation character.
Pilots should expect the following frequencies: Pittsburgh Approach/Departure on 124.75 MHz, Pittsburgh Clearance Delivery on 119.4 MHz, the AWOS-3 automated weather observation on 121.45 MHz, and a combined CTAF/UNICOM frequency of 123.05 MHz for airfield traffic and radio communications. An Altoona-based navigation aid, RDO, is listed on 115.8 MHz. The single runway, 08/26, carries an ILS on runway 08, supporting instrument approaches into the field.
As a non-towered airfield, traffic at Butler is coordinated by pilots self-announcing on the shared CTAF/UNICOM frequency of 123.05 MHz rather than through a control tower. Arriving and departing IFR traffic works with Pittsburgh Approach/Departure on 124.75 MHz, with clearance delivery available separately on 119.4 MHz.
The airport is located approximately five miles southwest of the town of Butler, Pennsylvania, which serves as a convenient visual reference for pilots inbound to the field from the surrounding area.
The airfield has been known under several names over the years, including Graham Field, Butler-Graham Airport, and Butler County-K.W. Scholter Field, reflecting changes in ownership and local naming through its history before settling on its current identity as Pittsburgh/Butler Regional Airport.
Today the airport functions as a general aviation field supporting local flying activity in Butler County, with published instrument approach procedures making use of the ILS on runway 08. It operates without a control tower, relying on the shared CTAF/UNICOM frequency for traffic coordination.
