FBO One sends handling confirmation messages as PDF documents by email to the operator. You can setup the body text of the email message that accompanies the PDF document in the email settings screen. It is also possible to send a text-only version of the handling confirmation, without the PDF attachment. You setup the text-only confirmation here.
It is also possible to automatically attach backup documentation to the handling confirmation email message. Examples of this are a flight chart of the airport, or the FBO price list. It is even possible to send information regarding particular third party services. For example, information about the hotel that was arranged for the crew, and how to reach it.
