Automated Flight Following A Technical Look….Past and Future Mike Russo – Technical Analyst Ministry of Forests and Range, Protection Branch Victoria BC, Canada HAC Quebec City, April 9th

Automated Flight Following (AFF) What is it? How does it work? Tracking Equipment / Reporting Frequencies Mapping Systems History AFF Specifications vs. Agency Requirements Satellite Technology Future? Who approves AFF compliancy? Automated Flight Following

Automated Flight Following (AFF) Regional Terrestrial Based “Pioneer System” / 02 Avionics industry to manufacture satellite tracking “system” / 01 A History… (In a Nutshell) Terrestrial and Satellite based systems ran side by side / 02 USFS approached BCFS for mapping display to track aircraft BCFS / USFS joint development in “AFF” standard / 04 BCFS went satellite based only Present DHC-8-Q400 flight from B.C. to Marseille, France BCFS portable systems for out of province aircraft. 2004

Automated Flight Following (AFF) What is AFF? “Automated Flight Following (AFF) is a system that automatically tracks the location, altitude, course and speed of an aircraft, providing this information in real time to dispatchers, aviation managers and other system users.” Safety! Resource Awareness! Reduce radio traffic! Reduce Check-in times!

Automated Flight Following (AFF) How does it work? 1)Tracking unit receives GPS data. 2) Tracking unit transmits data over satellite carrier. 3) Satellite carrier ground station receives data from tracking unit. 4) Ground station sends data over internet to Vendor headquarters. 5) Agency (ie: BCFS) requests data from Vendor. 6) Vendor sends data to Agency’s headquarters. 7) Agency formats data for display on mapping system.

Automated Flight Following (AFF) “AFF”

AFF Specifications One position transmitted every two minutes. Lat and Long in decimal degrees. Valid 3D positions will be used for tracking. Speed will report in “Meters per Second”. Data is secured between unit and AFF HQ. Etc… AFF vs. Agency Specifications Device must have external antennas. Device must have an STC / LSTC. One position report every 7 minutes. Device will run off aircraft’s internal power. Device must support voice capabilities. Etc… Look for a tracking device that is “flexible” Automated Flight Following (AFF) Agency Specifications

Automated Flight Following (AFF) Common Question #1: Can I guarantee the device and vendor are currently AFF Compliant? Currently, no vendor or device is “certified” as AFF compliant. Compliancy = “Performance Based” and “XML Data Standard”. Compliancy will be an “on going” performance evaluation. Performance is monitored and results displayed on a web site? AFF Compliancy can change overtime. Compliancy will be standard across North America. Available before 2008? AFF Compliancy?

Automated Flight Following (AFF) Tracking Equipment “Which Tracking Device Should I Buy?” Which satellite carrier does it use? (Transmission Costs) Can it meet the most demanding agency’s specifications? Does it meet my business needs outside forestry work? Are satellite voice capabilities important to me? Does it already have an STC for my aircraft? How much does it cost to purchase the hardware? Does the tracking device meet the AFF specs? Common Question #2:

Automated Flight Following (AFF) Satellite Technology “Which satellite carrier should I use?” Data and Voice Transmission Costs!! Satellite Coverage Area Voice Quality over Satellite Products / Hardware Available Satellite Bandwidth Speed Common Question #3:

Aircraft “History” Trail Five minute transmissions. Viewing two months of data. Points indicate transmissions. Web application. Automated Flight Following (AFF) BCFS “Dispatch” Application

Future? Eliminate 30 min safety check-ins? Send digital information from aircraft to base near real time? Reduce / eliminate the use of radio repeater network? Satellite only? Billing flight hours to tracking device start / stop reports? Send fuel levels and / or retardant levels to central Dispatch? Send manifest details over satellite? Record flight hours for maintenance tracking? Automated Flight Following (AFF) ????
