7. Other Instruments Are any of the following required ?
Mini-LIDAR (16kg optical head, 158 kg rack)
Manchester Aerosol Rack-SP2 (224 kg)
Any of the “new” racks, fitted/about to be fitted since the last instrument discussion in 2009:
CIMS/CW-QCLAS (224 kg)
Strathclyde 4C-PQCLAS (approx 140 kg)
LIF (approx 220 kg)
BBCEAS (220 kg)

8. Seats, WAS and Crew The weights shown are based upon:
All 9 pairs of seats fitted
A full set of WAS cases on board
An initial transit crew of 2 Pilots, 1 Operations, 1 Engineer, 1 CCM, 6 Science Crew (11 in total)
A crew in Canada of 2 Pilots, 1 CCM and 9 Science Crew

9. Aircraft Weight (with the Configuration Shown) for Science Transits
Basic Operating Mass = 28068* kg
Zero Fuel Mass with proposed minimum crew (2 Pilots, 1 Engineer, 1 Ops, 1 CCM) = 28409* kg
Science crew of 6 (92 kg each) = 552 kg
Mission 1, PTRMS, Core Chem, Flight Manager, WAS/Filters, AMS = 6
Zero Fuel Mass with crew (2 Pilots, 1 CCM, 1 Engineer, 1 Ops) + Science Crew = = 28961* kg
Max T/O Mass = kg
Therefore there is 13223* kg available for crew baggage, pack-up and fuel
Max fuel = kg
*Preliminary figures based on the current aircraft weight & balance manual
With 7 WAS cases in the rear hold, included in the BOM

10. Aircraft Weight (with the Configuration Shown) for Science Flights
Basic Operating Mass = 28068* kg
Zero Fuel Mass with crew (2 Pilots, 1 CCM) = 28225* kg
Science crew of 9 (92 kg each) = 828 kg
Mission 1, Mission 2, Mission 3, PTRMS, Core Chem, PAN/WAS, Flight Manager, AMS, Filters = 9
Zero Fuel Mass with crew (2 Pilots, 1 CCM) + Science Crew = = 29053* kg
Max T/O Mass = kg
Therefore there is kg available for fuel, but max fuel approx is kg
Therefore there is room for more instrumentation/crew and still allow a full fuel load on board
*Preliminary figures based on the current aircraft weight & balance manual
With 7 WAS cases in the rear hold, included in the BOM

11. Opportunities to save extra weight
The aircraft will be weighed after its repainting in May. The new paint scheme will hopefully save us weight
As we will strip the aircraft before painting, we will take the chance to remove redundant cabling etc
We could remove seats - including at the detachment base (34kg per seat-pair) if we have less crew on board
