Range	The range capability of the ARIA is influenced by: Aerial refueling capability Runway length, obstacle clearance, and noise abatement restrictions Runway elevation Runway air temperature Distance to alternate base Fuel reserve requirements Enroute wind conditions Aircraft altitude during data run Application of the above factors to some 25 worldwide airports produces maximum ranges varying from 2,800 to 4,500 nm without aerial refueling. Two ARIA currently have the capability to take on fuel while in flight. This greatly extends the maximum attainable range.
Navigation	Dual TACAN Dual VOR ADF radio Omega N-1 compass system* True airspeed indication system APN-59 search radar on EC-135E; RDR-1F on EC-18B APN-218 Doppler radar* Periscopic sextant Dual Inertial Navigation System (INS) Global Positioning System (GPS) *EC-135E only
