AIRCRAFT GENERAL DESCRIPTION

GENERAL DESCRIPTION

The Learjet Model 31A aircraft, manufactured by Learjet, Inc., are allmetal, pressurized, low-wing, turbofan-powered monoplanes. Thehigh-aspect ratio, fully cantilevered, swept-back wings with wingletsare of conventional riveted construction except for the upper sectionof the winglets, which utilize full-depth honeycomb core bonded tothe outer skin. The fuselage utilizes "area rule" design and is of semi-monocoque construction. Two inverted "V" ventral fins (delta fins)are fitted to the aft section of the tailcone to provide the aircraft withfavorable stall recovery characteristics and additional lateral/directional stability. Thrust is provided by two pod-mounted TFE-731turbofan engines manufactured by Garrett Division of Allied Signal.Each engine is provided with an independent fuel system with fuelstorage provided in the wing and fuselage tanks. Engine-driven hy-draulic pumps provide hydraulic power for braking, extending or re-tracting the landing gear, wing flaps, spoilers, and thrust reversers.Fully retractable tricycle-type landing gear with dual main gearwheels, anti-skid braking system, and nose-wheel steering is utilized .The ailerons, rudder, and elevator are manually controlled throughcables, bellcranks, pulleys, and push-pull tubes. An electrically-actuated trim tab is installed on the left aileron and rudder to providelateral and directional trim. Longitudinal trim is accomplished bychanging the incidence of the horizontal stabilizer with an electrical-ly-operated linear actuator. Aircraft air conditioning systems provideheating, cooling, and pressurization for the crew, passenger, and cab-in baggage compartments.

COCKPIT DESCRIPTION

The instrument panel and pedestal are accessible and readable by ei-ther crew member. Circuit breaker panels are located on the cockpitsidewalls. In some aircraft flashlights are installed above the circuitbreaker panels . In some aircraft a pencil holder is installed under theglareshield on both the pilot's and copilot's side . A magnetic compassis installed on the windshield center post. The side panels above thearmrests contain the oxygen control valve (pilot's side), instrumentlight controls, oxygen masks, and smokegoggles. No switches (exceptdome light switches), instruments, or placards are located overhead .Map storage is provided in the aft portion of each armrest. The pilot'sand copilot's seats (figure 1-8) are adjustable forward, aft, and vertical-ly. Acurtain or door, located behind the crew,maybe closed for privacyor to darken the cockpit.Ahandheld fire extinguisher is readily acces-sible to the crew.

CABIN DESCRIPTION

The aircraft cabin is divided into two areas: the passenger area and thebaggage compartment. Access to the baggage compartment, located inthe aft cabin, is accomplished through the cabin. Thecabin window ad-jacent to the wing leading edge on the right hand side of the cabinserves as an emergencyexit . Individual reading lights, fresh-air eyeballoutlets, and passenger oxygen masks are located in the overhead con-venience panels above the seats.

Specific seating arrangements and passenger accommodations are se-lected by the owner and are not included in this manual.
