I've made some tweaks to the Simbrief-integrated profile for the Hot Start Challenger:
switched backend weights to pounds for greater granularity
MLW in pounds is no longer rounded to 37,999 instead of 38,000 lbs
airframe still works with either unit just like before
tweaked passenger weight to 165 lbs (~74-75 kgs) with 30 lbs (~13-14 kgs) per bag
still allows for 5 passengers, full fuel just below MTOW (w/default taxi fuel)
added a default Mode-S Code
required for successful CFMU validation when aircraft is J1-equipped
changed default airframe registration from N650HS to N650CL following feedback by Pilsner on Discord
it looked like it didn't take at first, but appears to have propagated to wherever it needed to now, as far as I can tell
added a default fin number (6050)
apparently the first Challenger 650 was MSN 6050; thanks, Pilsner
