The Cessna Citation II (PH-LAB) is the research aircraft operated by NLR Flight Test Operations. It offers opportunities to perform flight test applications in a flexible and affordable way. The aircraft is operated from the Amsterdam Airport Schiphol in the Netherlands. 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.
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 fugelage 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.
The aircraft can be operated single-pilot IFR/VFR, allowing display and/or procedure evaluations by the customer from the right hand seat. The aircraft has been operated in different parts of the world, including cold weather areas and remote locations.
