SUMMARY

The angle of attack (AoA) for hang-gliders, paragliders, and sailplanes in still air is critically defined by their glide ratio. With a glide ratio of 4:1, the flight path is established at 14 degrees relative to the horizontal. The acceptable range for AoA is between greater than 0 degrees and less than 14 degrees, as exceeding 14 degrees typically leads to stalling. While cruise AoA for most aircraft is between -3 degrees and 5 degrees, hang-gliders likely follow a similar pattern due to their design as flying wings.

PREREQUISITES
  • Understanding of angle of attack (AoA) in aviation
  • Knowledge of glide ratios and their implications
  • Familiarity with stalling conditions in aircraft
  • Basic principles of aerodynamics related to hang-gliders and sailplanes
NEXT STEPS
  • Research the aerodynamic principles of hang-gliders and their design characteristics
  • Learn about stalling angles and their effects on flight performance
  • Investigate the differences in glide ratios among various types of gliders
  • Explore the impact of environmental factors on angle of attack during flight
USEFUL FOR

Aerospace engineers, flight instructors, hang-gliding enthusiasts, and anyone interested in the aerodynamics of gliding aircraft.

My question is, how high can be the angle of attack of a hang-glider, paraglider (the canopy) or a sailplane, gliding in still air.

Assuming a small glide ratio of 4:1, tha flight path is at 14 degrees with the horizontal line. If the glider was at the angle of attack 14 deg, that would mean he is parallel to the horizontal.
I understand, that the possible correct AOA are >0 and <14. Is this right? Is it possible for the AOA to be higher than 14 degrees?

Stalling would typically occur at \alpha &gt; 14^omore or less, this is not a cruise AoA. Any aircraft typically can cruise at -3^o&lt;\alpha_{cruise}&lt;5^o. I am not sure about hang gliders but I would assume the same would apply since it is only a flying wing.
