Assumptions Jason Cornelius
• There is value to keep the 2nd attendant seat in the cabin
– 505 EMS Kit could be sold in the United States
• First Responders will be on scene prior to aircraft arrival
• Goal of Bell cost (for mat’l, manf, labor of installation) is 5% of the aircraft price
• Determination of Non-Recurring Engineering (NRE) cost is considered out of scope for this project
