1.2 DESCRIPTION
The Esqual is a two seater light plane manufactured in carbon fibre with high density PVC
foam and Epoxy resins. Laminated in a mould and vacuum cured in an oven at constantly
controlled temperature and humidity. The fuselage is monocoque.
The low cantilever wing has positive changing flaps (as high lift devices). The wing structure
has a composite sandwich skin with a main double “T” composite spar and an accessory spar
near the trailing edge.
The empennage has a conventional cross shape.
The cockpit seats are side by side.
The landing gear of the Esqual has a classic tricycle gear which is made of 7075 T6 aluminum
grade. The main gear legs are suspended in the main carry through beam together with the
reinforced wing spar zone.
The nose gear leg is supported in the engine mount and equipped with a free swivel nose wheel.
The main wheels are equipped with independent hydraulic toe brakes for steering.
The safety belts have four anchoring points.
The rudder pedals are adjustable in flight.
The luggage compartment (with 50lts capacity, 18 kg) is located behind the seats and can be
accessed during flight.
An optional ballistic parachute can be mounted.
The safety reinforced cockpit has twin axle composite beams all around its frame.
Independent ventilation openings are standard; a cabin heater is an option.
1.3 REFUELING
There are two independent fuel tanks, one in each wing, with their openings on the upper
surface. The fuel caps do not protrude over the wing surface and can be unscrewed with the
Esqual key-ring. It is always recommended to filter the fuel and to attach a mass wire to the
exhaust pipe when refueling.
