What is the difference between an aircraft owner, aircraft manager and approved pilot?

In AlfaCharlie the aircraft owner is the user who created the aircraft in AlfaCharlie. This can be a flying school, a club or a private user. Aircraft owner see their aircraft in the view Aircrafts under the tab Aircrafts I own.

In the case that the aircraft owner does not want to administrate the bookings on the aircraft himself, it is possible to appoint one or several contacts as aircraft manager. 

Aircraft manager

Aircraft manager can edit the aircraft profile and approve pilots for the aircraft. They also have the the rights to approve or deny booking requests and to change or delete bookings.

Manager see the aircrafts they are appointed as manager under Aircrafts I manage in the view Aircrafts. 

Approved pilots

These are users, which have been approved for a specific aircraft by the owner or one of the managers. Usually, these are club members or customers of a charter operator. Approved pilots can see more details of the aircraft booking calender and can also make booking requests.
