|Seats available for scientists||
Two seats side by side. Small "baggage" area for payload behind seats, max 30 kg
adapter plate for small inlets
Port side underwing pod fitted with view ports for optical sensors; these are open ports.

On each underwing pod; available via storm window and baggae area port.
Data is generally logged locally within each functional system as well as key outputs being redundantly logged centrally (2 x CSI CR1000 dataloggers) and, in some cases, on other systems where such data may be relevant. All systems are networked and real time monitoring /control as well as data retrieval are performed remotely via a central 'Control/Display Computer' (the exceptions being hyperspectal and photograhic imaging, where swappable SSD / memory cards are used for data transfer). Data may also be retrieved across the network directly to an external ruggedised PC with local RAID storage and hot-swappable drives via umbilical. The network also provides system synchronisation via GPS-based NTP signal (which is also broadcast in NMEA/PPS for precsion synchronisation where available).
|Aircraft total electrical power (kW)||
|Electrical power (kW) and voltages (V) available for scientists||
0.8 kW; Each payload bay (i.e. each pod and the cabin) is provided with 6 independently switched circuits as follows: 2 x 28 VDC; 2 x 14 VDC; 1 x 5 VDC; 1 x 115 VAC single phase 60 Hz.
