B4-PC11
Pilatus B4-PC11 AF D-3993.jpg
Role Club-class glider
National origin Switzerland
Manufacturer Pilatus
Designer Manfred Herbst and Rudolf Kueppers
First flight 7 November 1966
Number built 322

The Pilatus B4-PC11 (also known as the PC-11 in the Pilatus numbering sequence) is an all-metal intermediate glider built by Pilatus Aircraft of Switzerland.

The B4-PC11 is designed to Standard Class specifications, which means that it has a 15 metre wingspan and no flaps. Air brakes are provided on the top surface of each wing for glidepath control. Construction is aluminium, with foam ribs in the mainplane, fin and tailplane.

Development[edit]

The design of this glider originated in the 1960s, when the company Firma Rheintalwerke G. Basten (from which the "B" in the original designation is derived) manufactured the first two prototypes. The designers were Manfred Herbst and Rudolf Kueppers. The first flight of the first prototype took place on 7 November 1966. However, no series production was started.

In 1972 Pilatus bought the manufacturing licence for the B-4 and renamed it the B4-PC11. In the spring of the same year the first production example (numbered HB-1100) undertook its first flight.

A total of 322 B4-PC11s of all versions were built by Pilatus by 1980, when the license to manufacture the craft was sold to Nippi Aircraft of Japan, who only built 13 examples, plus a two-seater designated the Nippi B4T.[1]

Subsequently, in 1994, EWMS Technomanagement bought the rights to produce and service the B4-PC11. This company also specializes in renovating and upgrading older B4-PC11 craft. In addition, it manufactures a motorized B4-PC11.

Variants[edit]

B4-PC11
permitted to fly a number of aerobatic manoeuvres, it was not permitted to do inverted loops or flick/snap/quick maneuvers. The B4-PC11 was available with either fixed or retractable landing gear.
B4-PC11A
developed to perform inverted loops and was also able to handle higher g-forces.
B4-PC11AF
released in 1975, with full aerobatic capabilities.
Lynch B4M1
a motor glider conversion in Australia by John F. Lynch, powered by a 17.9 kW (24.0 hp) König SC 430 engine.[2]

The changes in construction from B4-PC11 through A and AF variants were to add extra ribs through the fuselage section (increasing torsional rigidity), and to modify the control column stops and shorten the rudder giving greater control surface deflection.
