  2. From Science Fiction… “The telescreen received and transmitted simultaneously… There was of course no way of knowing whether you were being watched at any given moment… It was even conceivable that (the police) watched everybody all the time… You had to live… in the assumption that every sound you made was overheard and… every movement scrutinized.” George Orwell, 1984 (1949)

  3. …To Today’s Reality The Washington Post 26 Aug 2001 p.C2

  4. Lessons in Forecasting • Yesterday’s outlandish predictions tend to become today’s mundane reality - What would a cabbie of 1949 think of the 2001 photo? • You have to look backward to measure progress forward - Change is seldom appreciated while it is happening - Orwell was off by 17 years (1984 v. 2001) = 50% • Socio-economic factors govern technology progress - Cameras in cabs driven by cost and frequency of crime • The future always holds wild cards - Who forecast the appearance of the internet?

  36. Technology Driving Markets • The aviation industry is not the driver for UA-relevant technologies

  37. UA Customer Forecast … but even if the technology becomes available, unmanned aviation will need an economic reason to grow. • What will the customer base for unmanned aviation look like in 2025 or 2050? - How many? - When? - Why? • Five markets: - Airlines and Cargo Carriers (Parts 121 and 135) - General and Business Aviation (Part 91) - Military

  43. Positive Influences on UA Growth • Military - UA program trends - Pathfinding efforts (S&A, standards) • Cargo Airlines - Long term drive to reduce crew size - Long, dull, no-pax missions into Class C airport hubs - Expressions of interest by airlines • General Aviation - NASA Personal Air Vehicle Exploration (PAVE)--2009 demo - FAA expectation of ‘mini-jets” - Flashover point in commute distance

  44. UA GROWTH BY IFR SEGMENT
