Issoire APM 20 Lionceau
The APM 20 Lionceau began as the Moniot APM-20 in 1992, by Les Industries de Composites d'Auvergne Reunites (ICAR).
Designed by Philippe Moniot at Rex Composites and certified in 1999 EASA CS-VLA, the APM 20 Lionceau is a very light (400 kg empty, 634 kg loaded) and economical 73.5 kW (98.6 hp) Rotax 912 ULS powered aircraft is primarily intended to be used to learn to fly, but also to travel with a relatively high cruise speed (113 knots).
Manufactured by the French manufacturer Issoire Aviation, it is entirely built from composite materials, especially carbon fibers. Design (as Moniot APM-20) was started 1992 by Les Industries de Composites d'Auvergne Reunites (ICAR).

The design features a low wing, NACA 63618 aerofoil, thickness/chord ratio 18 per cent, dihedral 3o, incidence 2o, twist 1o. The structure is Carbon fibre/epoxy. Flying controls are conventional and manual. Spring elevator tab for pitch trim.
Electrically operated slotted flaps to about two-thirds span. A refuelling point is on the port side of fuselage.
The landing gear is fixed tricycle type with spats; oleo-sprung steerable nose leg, composites main legs. Mainwheels and nosewheel diameter 330 mm; maximum pressure 2.35 bar (34 lb/sq in).
Two, side by side seats are under rearward-sliding tinted canopy. Dual controls standard. Baggage compartment at rear of seats. Fixed step forward of wing leading-edge on each side.
The prototype (F-WWMP) exhibited at Paris Air Show 1995 before first flight on 21 November 1995; third (second flying) aircraft (F-WWXX) exhibited statically at Paris Air Show, June 1997, fitted with JPX flat-four engine, which is not offered on production aircraft.
No.4 (also registered F-WWXX) was exhibited at Paris in June 1999 and No.5 (F-GRRE) in 2001.
They were certified to JAR-VLA on 17 May 1999 and to JAR-21 in 2000. The first all-carbon fibre, single-engine aircraft to gain JAR-VLA certification.
Development cost around FFr10 million. Unit cost FFr620,000, minimally equipped or FFr700,000 with standard equipment (2001). Operating cost FFr350 per hour (1998).
First flying in December 1995, the Issoire Aviation APM 20 Lionceau is entirely built from composite materials, especially carbon fibers. Production is carried out by Issoire Aviation.

The APM-22 Liondo was the prototype APM-21 F-WWMP equipped with large winglets and exhibited at Paris, 15-22 June 2003, as representative of this UAV proposal, with 24-hour endurance and 556 kg (1,225 lb) MTOW

APM-22 Liondo
A three-seat version, the APM 30 Lion, was presented at the 2005 Paris Air Show.
