Oh wow. I didn't know bad angle of attack is the only thing that can make a wing stall. This means I can fly level at 2 mph! I'm going to try that the next time I get to fly a real plane!
Yes, you need to do some reading, but there is also some free video on the internet that will do a good job explaining AOA, Relative Wind, cord line.
this from the FAA
"The widespread presence of angle-of-attack indicators in general aviation aircraft could reduce fatal loss-of-control accidents caused by inadvertent stalls, said the FAA, announcing an initiative to promote installing the devices in aircraft and educate pilots in their use.
In an Information for Operators (InFO) publication released July 25, the FAA’s Flight Standards Service called for voluntary installation of angle-of-attack (AOA) based systems in GA aircraft as original equipment and for retrofitting. The InFO, geared toward airmen, builds on a previously issued policy memo from the agency’s Aircraft Certification Service on "streamlining the design and production approval process of non-required/supplemental AOA-based systems for GA airplanes."
Notice they are not talking about airspeed to prevent stalls. Remember that any aircraft will stall at any airspeed fast or slow. It's the AOA that causes a wing to stall..
