The Mission Request Vade Mecum has been developed to help emergency front-line personnel to safely deal with helicopters. Policemen, firefighters, ambulances, and all the personnel who may be involved in requesting and handling a helicopter mission will benefit from the tool. A comprehensive document explains what information should be given to the helicopter pilot and describes how to set up the landing area. Together with the emergency dispatch centre they can go through the R.O.M.A. checklist in order to quickly check all the required information and safety provisions. Finally, a ready-to-use Mission Request presentation can be tailored by the training organisation in order to spread the operational and safety knowledge to the front-line personnel.
