Hello Kyle
I find acft-handling in slow landing and t/o speedis very good - its a pilots aircraft - if you adopt to the nose down attitude during landing...
CL850 is delivered by bombadier as a CAT D (instrument appr.) aircraft with MLM of 21319 kgs (VREF 141kts) if you manage to "downgrade" to 21205 (VREF 140) with your CAA you might benefit from CAT C and hence lower minimums.
Also some 850īs are capable of CAT II
Wing issues:
YES definitely be careful in your winter ops - those wings have to be treated carefully
Performance:
Landing Perf. is not an issue with proper landing technique - T/O with Mtom requires at least 2200m (donīt have my books with me now..)
Extra fuel tanks: NO
no need to fix another tank - example:
typical ZFW with two pilots and FA: 15800kg (1000kg more than airliner CRJ)
MAX Fuel: 8200kg
1 PAX: 100kg incl Baggage
MTOM: 24040kg
Range:
needed fuel stop for LTN-DXB
