Lemhi Aerospace

Lemhi Aerospace is an aerospace manufacturer located in Sandpoint, Idaho. It employs 40 people. Lemhi produces private turboprop and jet aircraft capable of short takeoff and landing (STOL) operations.

History
Lemhi Aerospace was established on 29 April 2002 by Thom K Henson, his second company. The company was formed as a competitor to Trump Air. Lemhi currently has two products on offer, the LX-208 and LX-218. Both are capable of STOL operations, the LX-208 being powered by turboprop engines and the LX-218 being powered by turbofan engines.

Lemhi LX-208
The Lemhi LX-208 is a single-engine pressurised turboprop passenger and cargo aircraft designed to perform multiple roles and to deliver performance and safety equivalent to twin-engine aircraft. It is powered by a Pratt & Whitney PT6A-67 engine. The aircraft is notable for being able to operate in rough and rugged environments.

Layout
The cabin can accommodate up to nine passengers and features a refreshment centre, an enclosed lavatory and a rear baggage area. Other cabin configurations include executive arrangements, seating between six and eight passengers, a four-seater passenger-cargo combination layout and an air ambulance setup. The interior was designed in conjunction with BMW's Designworks division, using various textiles, leather and fine wood veneers.

Operational Design
The LX-208's PT6A-67 engine has a reputation for being at the top of its class in terms of dispatch reliability. To counteract stall-spin conditions, dual angle-of-attack sensors near the wingtips force the control column forwards prior to a potential stall. For redundancy, the LX-208 has a complete split-bus dual electrical system found more commonly on modern jetliners. The LX-208 hosts a type rating certifying it for operations in icing conditions. The aircraft features three-axis autopilot, weather radars, long-range navigation systems and radar altimeters. The flight deck hosts Honeywell's Primus Apex avionics system, hosting four high-resolution liquid crystal display screens.

Specifications
The LX-208 can be operated by one pilot. The aircraft measures 14.4 metres (47ft 3in) in length and 4.26 metres (14ft) in height. It has a wingspan of 16.28 metres (53ft 5in) and a wing area of 25.81 square metres (277.8ft2). The aircraft's cabin measures 5.16 metres (16ft 11in) in length, 1.47 metres (4ft 10in) in height and 1.52 metres (5ft) in width. The aircraft has an OEW of 2,810kg (6,195lb), an MTOW of 4,740kg (10,450lb), an MLW of 4,500kg (9,921lb) and an MZFW of 4,100kg (9,039lb). The aircraft can hold up to 1,226kg (2,703lb) of fuel, has a range of 1,845 nautical miles, cruises at 285 knots, stalls at 67 knots, climbs at 1,919ft/min and has a service ceiling of FL300. The aircraft has a takeoff run of 793 metres (2,602ft) and a landing run of 661 metres (2,169ft).

Orders
The LX-208 currently features no orders. Lemhi places a $3.2 million base price on the aircraft.

Lemhi LX-218
The Lemhi LX-218 is a dual-engine light business jet designed to be an upgraded version of the Lemhi LX-208. It is powered by two Williams FJ44 turbofan engines, and is one of the only business jets capable of operating in rough and rugged environments.

Layout
The cabin room has room for eight passengers and two pilots. The cabin has three exits, and features a standard pallet-sized cargo door found more commonly on large cargo transport aircraft. The interior colour schemes were designed by BMW's Designworks division.

Operational Design
The LX-218 features two Williams FJ44-4A turbofans mounted on the side of the rear fuselage, hosts a T-tail and a tricycle rear-stroke landing gear configuration to avoid sinking into soft surfaces. The aircraft hosts a double-slotted flap system to achieve greater performance. The flight deck features Honeywell's Primus Epic 2 avionics system, which hosts four large and two small liquid crystal display screens. The aircraft also features three-axis autopilot, weather radars, long-range navigation systems and radar altimeters. The LX-218 is one of the few business jets to be single-pilot certified.

Specifications
The LX-218 can be operated by one pilot. The aircraft measures 16.85 metres (55ft 2in) in length and 5.4 metres (17ft 4in) in height. It has a wingspan of 17 metres (55ft 9in) and a wing area of 30.91 square metres (332.6ft2). The aircraft's cabin measures 7.01 metres (23ft) in length, 1.55 metres (5ft 1in) in height and 1.55m metres (5ft 7in) in width.
