Plates are NOS, provided by the company. If you want to use Jepp, you have to buy them yourself.
Barons are based in RDU, with one based in JQF (Concord, NC). Right now, there's also a Baron based in Macon, Ga., but that's because the pilot flying that run used to be the Baron pilot in JQF. When he moves on, they'll probably put a Seneca there.
We have 4 C-402s. One is based in Wilmington, NC, and the other in New Bern, NC. Both are used for Airborne Express. These guys fly to RDU in the evening, sleep in the office and fly back in the mornings. Those runs are pretty locked in as both pilots have family in their respective cities. The other 402s are kept in RDU as spares and for on-call charter work, usually for UPS when one of their feeder planes breaks down or a plane is late.
Richmond is an all-Seneca base.
