In line with my original intention on this post, more aircraft are bent in practice for an emergency that are ever bent in a real emergency.
Talk to Frank Robinson about the extremely low number of R22 that have been damaged in a real engine failure in the hover, compared to the regular rolling up that happens in practicing for them - student fouls up and pulls up on lever instead of freezing, and crunch.
Others are so paranoid about having an engine failure when taxying, that they lower their taxy height so they won't spread a skid. Frank will tell you that he has never lost a Robbo from taxying too high, but there are hundreds of dents in the ground, surrounded by broken plexiglass and rotor slash marks, from taxying too low.
Taking every auto to touchdown may make the pilot and instructor very confident about landing on a firm airfield, but in real life the ground is not going to be level, grassed and capable of holding an aircraft. More likely it is some farmer's ploughed field, or a rocky hillside, or a forest. Time is better spent on power terminations - the aim of the game, after all, is to position the aircraft and manipulate the glide to put yourself in a position to touch down. If you can do this, you are 98% of the way home. The last 3 feet is in God's hands, depending on the surface condition. And in the practice, you are avoiding the likelihood of digging in a skid and scaring the cr@p out of all concerned. Been there, done that. Bought the T-shirt, and it has worn out.
