That 206 incident was during a pleasure lfight at an event. Notice the position of the windsock when he flies past it after the incident... downwind! Routines like this should always be finished in to wind and be flown by experienced pilots who know what their doing, unfortunately they too can make mistake and misjudgements. Dennis K's prang in the states is an example.

I'd very much go along with Haggis Hunter. Nice to see/practice with an experienced instructor only. There's a reason why it's not in the syllabus.

Um, I think CrashAire has a curriculum. Only thing, it's not retake-able. Laughing

As to what that maneuver was called is still up for grabs, but at the end of the video, the banner refers to it as a Bell 206 Hammerhead.

I think the only 'hammerhead' was the pilot who almost became 'turfhead' .

I heard they are going to add it to the CFI course. Laughing

The general definition of a hammerhead is as you would see it if you threw a hammer vertically.

It would sail up head first, stop, start to descend tail first, then flip onto its back or flip over forwards, and come down head first again.

In a helicopter, that can only be done in a rigid rotor like a BO 105 or BK 117. A teetering head will come off.

The move that has been described before is a torque turn, with the nose always leading the movement. It is a common practice in ag flying, to go from speed at low level in one direction and reverse it 180 to start again in the same spot, displaced slightly to one side.

I'll stick to the simple up/down and straight/level.

Laughing Getting too old for aero-gymnastics.

Torque turns and anti-torque turns were part of my training..many moons ago.... and I use them daily (mustering) though not at the speed and severity of the video. Once you get then down pat it saves a lot of stress on pilot and machine...the aerodynamics do all the work. I find the ideal situation is when flying cross-wind....torque turn into wind and anti-torque turn into wind on the following turn...you are turning into wind when at slowest airspeed.

I was told that the 206 featured in that video was (a) brand new at the time of the 'airshow', (b) the 'airshow' pilot was NOT authorised to conduct any such manoeuvre (it was supposed to be a benign level fly past), and (c) the resulting UNINTENDED touchdown damaged the aircraft. Oh, by the way, because the damage was caused by flying the machine in a way it wasn't intended to be flown the damage to components wasn't covered under warranty AND Bell refused to do anything to certify that machine post repair...it ended up being a complete write-off.

A cheap lesson for all you folks on the early part of the flying career...someone is always watching and if it feels like your tempted, THINK CAREFULLY before acting. More people get into strife doing that flypast or beat up after a family flight and thats where things come unstuck.

Hasta las vegas
