Self Launch/Motor Gliders

     An aside on justifications,
 misconceptions and capabilities of
        self launch gliders
 Self Launch/Motor Gliders
• Opportunity
  – Launch when/where you want
  – Self deploy and safaris
  – Landout avoidance - Push harder,
    experiment, fly in more marginal conditions
• Not “Tow plane avoidance”
• Disadvantages
  – Complexity, reliability, maintenance
  – Safety (complexity, engine failure TO, stall
    under power, poor risk judgment)
  – Cost
