in IND i sat 1 month of reserve once i could bid. in ATL or ORD, get ready to spend a lot of time waiting by the phone.
coming from the 145 will be a near cake-walk. the FMS is very similar to the honeywells in the 145, the switchology is identical, and the panels and systems are almost identical. only difference is more things are automated and you can take off your headset at cruise.
