Scientific Description
The Cessna Citation II research aircraft offers opportunities to perform a wide variety of flight test applications. Extensive modifications have turned this pressurised, twin-engined business jet into a versatile airborne research platform.Flight test topics range from aerodynamics, flight mechanics, zero-gravity, atmosphere, airborne remote sensing and flight test methods, to system tests, air traffic management, avionics, alternative fuel, and flight inspection.

Access to modified and instrumented Cessna Citation II research aircraft

You can get access to the flight testing services through an agreement with NLR.

Cessna Citation II modified research aircraft

The aircraft (PH-LAB) has a maximum payload of 1400 kg (incl. crew), range upto 3000 km, endurance of 5.30 hours, max speed of 840 km/h (Ma 0,705) and maximum operating altitude of 13000m (FL 430). The aircraft can be operated single-pilot IFR/VFR, allowing display and/or procedure evaluations by the customer from the right hand seat. As EASA part 21 holder, NLR has the autonomy to modify aircraft systems. For flight test purposes the aircraft features: - a separate electrical system dedicated to powering onboard test equipment - an additional stand-alone 3000 psi hydraulic system - provisions on fuselage for mounting an external pod - numerous facilities in cockpit and cabin for accommodating test equipment - an antenna box on top of the fuselage that can accommodate multiple antennas - underwing panels configured for antenna installation - a noseboom with alpha/beta vanes or five-hole probe - a fuselage fairing accommodating a forward facing optical glass - several metal plate inserts that can replace existing windows and can accommodate flight test equipment. Available flight test instrumentation consists of: - Inertial Reference System - Digital Air Data System - GPS high-accuracy positioning system (phase tracking) - Multi-channel digital data acquisition and recording system (general aircraft state parameters are real-time available in cabin) - Iridium SATCOM - Liquid Water Content sensor - Humidity sensor - Telemetry system - Digital integrated avionics system in cockpit, offering opportunities to test new experimental display formats in flight.
