ylhelico, I do not agree with you as far as having a stuck pedal. The amount of coanda effect is also affected by the air coming out the slots from the fan. The pitch of the fan is directly connected to the pedals. Lots of air means lots of anti-torque you do not need. And add the thruster equation to that also.. .. .What is worse, is the manual says that if you have a fixed thruster setting "Use powered landing, otherwise it is unlikely that an autorotation can be accomplished.". .. .I am not sure if you have practiced something like a stuck right pedal (say pushed by the instructor 1 1/2") to touchdown. The factory pilot says in that case, touchdown needs to be in the area of 60 kts or greater. <img border="0" title="" alt="[Eek!]" src="eek.gif" /> There is another method of a manuver simular to a power-on auto, making the nose swivel to the left on your decent and touching down at about 10 kts as the nose is swinging right. . .. .There is no question about the safety of the NOTAR as far as the tailboom hitting something verses a tailrotor.. .. .Part of my job is searching for lost hikers in the mountians. I do a lot of confined ops along with one-skid/toe operations. The difference in control between the two is vast. The NOTAR is like a wallowing pig compared to a tailrotor. And we could add the lack of power they have. . .. .Nick, the best we have been able to get the MD people to admit to is anywhere up to 210 hp to run the tail when asking for a bunch of anti-torque. I believe that the most the "E" will grab is around 65 hp. And even though the NOTAR burns around 6-8 gallons more an hour, inorder to carry the same that a 500E will, we have to carry less fuel.
