Only ignorance can explain someone who would call a Lancair a toy. The Lancair IV-P is the highest performance piston single-engine aircraft ever built.
Oh please....only an internet troll with flamebait intentions would bring the word "ignorance" into this discussion especially after I explained my comments once already.
Most here understand that my reference to "toy" was not indicitive of the performance of the airplane. It was in reference to Lanair's non-certified status of the kit line. And I stated that.
For better or worse, you can pretty much do what you want on the uncertified kit planes without oversight of the regulator. So lots of junk finds its way into these cockpits. Furthermore, I was making reference to the Lancair line's utility. You certainly won't (ever) see a Lancair IV
-P in commercial service. Thus it is a truly recreational aircraft and fits the "toy" category quite well when compared to a C206.
Actually, there are quite a few on very simple aircraft, like the mutltitude of Quicksilvers.
Another "toy" that enjoys even less utility than Lancairs.
Since an aircraft doesn't stall due to airspeed, but only the angle of attack of the wing relative to the airflow, yes, AOA indicators are valid pieces of equipment even for a Cessna 206. They allow you to fly the aircraft right to the limits with full confidence that it will not stall/spin/kill you.
Valid? What does that mean exactly? Usefull? Required? Pretty much anything can be installed on any airplane. That doesn't automatically make it a practical device.
TCAS is "valid" and so is TAWS and weather radar. But will you typically see that stuff on a Quicksilver, Lancair or Cessna 206? Umm...no.
And with respect to flying the aircraft "right to the limits", Bad advice. I would certainly hope that the majority of private pilots would NOT consider an indicated AOA system license to do that. Fly the airplane within the published approved limitations using the AOA indicator as a warning system and you will stay out of trouble. Conduct performance takeoffs using an AOA indicator pegged on the outer limits of the green arc, and you will crash one day....
