Description

The Pilatus PC-7 Turbo-Trainer is a single-engine, tandem two-seat turboprop aircraft designed to perform training missions for military customers. It was developed by Pilatus Aircraft in Switzerland. The first PC-7 prototype performed its maiden flight on April 12, 1966, and the first production aircraft first flew in August 1978. The first production aircraft was delivered in December 1978. The Pilatus PC-7 trainer received a large number of orders in the 1980s entering into service with over 20 air forces providing basic training becoming thus the most successful military aircraft program for Pilatus Aircraft.


The PC-7 Mk II trainer was developed by Pilatus Aircraft to meet the requirements of the South African Air Force (SAAF). Known in South Africa as the Astra, it first flew in 1992 with the first delivery to the SAAF in early 1994. The Mk II features a more powerful Pratt & Whitney Canada PT6A-25C turboprop engine (700 hp), a four-bladed Hartzell propeller and airframe enhancements from the Pilatus PC-9 trainer.

The SAAF has 52 Astras in service. One is used for test flying at AFB Overberg, 6 are used by the Silver Falcons and the remainder is used for ab-initio training at the Central Flying School at AFB Langebaanweg. Approaching its mid-life, the Astra trainer will soon be equipped with a new instrument panel and undergo a state of-the-art avionics upgrade.
