Does anyone know of any good flight department staffing models? We just added a signifigant amount of flying to our already busy operation. Trying to justify the additional head-count that we're going to need to have any QOL is always a challenge with our owner. I know there are some models in the NBAA managment guide, but I don't have a copy. Right now we're staffed at 1 crew per airplane @ about 350 hours a year per a/c. Expecting about 450 hours per a/c moving forward. Thanks.
