|Seats available for scientists||
main doors : W0.86 m x H1.78 m (two forward, two afterward).
Upper and lower lidar windows in real fuselage. Standard fuselage windows can be replaced by mountings for lightweight instruments.
Range of hard points for intakes around the forward fuselage. Hard point under each wing (outboard of engines) carrying pylon with 5 mounting locations for standard PMS/DMT canister instruments.
Aerodynamic external blister on port forward fuselage, containing 3 bays for mounting radiometers. Instruments in blister have views of both zenith and nadir. Bays can be adapted to a range of instrument mountings.
