The Alap-Alap Formation display team uses three of the four RBAirF / TUDB
Pilatus PC-7 Mk.II turboprop aircraft purchased from Switzerland in
1997, a low-wing tandem-seat training aircraft powered by a
PT-6A-25C turboprop engine driving a four-blade variable-pitch
propeller. All four PC-7 aircraft of the RBAirF are liveried in a white, blue, red, and yellow colour-scheme. The three aircraft used by the Alap-Alap Formation display team (
registration numbers: TUDB-302, TUDB-303, and TUDB-304) are fitted with two under-wing smoke pods, mounted on external hard-points, which generate white smoke during displays. ==Operation==
