Detailed description of the facility
The Cessna Citation II aircraft is operated from the Amsterdam Airport Schiphol in the Netherlands
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)
Liquid Water Content sensor
Digital integrated avionics system in cockpit, offering opportunities to test new experimental display formats in flight.
The aircraft is operated in partnership with TUDelft.
