  1. Many of the maxi yachts no longer have mast stays, with the power in those sails, the masts manage it.....amazing
  2. 22’s never ever full auto to ground, never. Low inertia blades dont give much room for error, if any. 44’s heavier blades good, but rare to find instructor / company that will allow auto to ground. There must be some around the traps that do auto somewhere. Heard the 206 etc can auto to ground and then lift again and rotate 180........that’s impressive ...
  3. 98.4% (-: of incidences are weekend worriers, total hrs per yr less than 50. The musterers log up 100’s +, running out of fuel pops up, blade strike on them pesky trees comes up, the flick and bank rarely comes up.
  4. Ok......power push over.......you’re on a powered nose high climb, and you shove stick forward to commence a descent. The gyro will pendulum at a point at that roll over and the rotors will strike the tail...game over. 1 alternative is.....power off, EASE stick forward, so you gently roll over, over she goes then commence descent in the normal safe way. there are several ways to go from hard climb to immediate descent, but i won’t explain here, it needs to be hands on with suited instructor, don’t want a pilot reading here, and going out to give it a try. loss of control........mec
  5. Who’s “they”.........lots of “stories” get spread out there, some are true, many false, many exaggerated.
  6. @ wara ........i heard asra had abandoned a vital service ( forum etc ) why ???? It’s just crazy logic. Folks lurking / seeking info have lost a great service. The “HF” is another strange logic, new faces onto committees etc can bring crazy ideas sometimes. asra began a strange pathway about 10yrs ago, has resulted in many members being disappointed. Safety has always driven asra, and thats a good thing, instructors are regularly assessed to maintain standards, thats another good thing. The cost of some machines blows me away, almost half the cost of a half decent 44 with good
  7. At fact.........Blades have an infinite life, the hub bar is the worker, hence they must be crack tested ( X-ray or dye penetration ) every 500 or so hrs, or whatever the manufacturer states, could be even more / less. Blades........the system is a “teetering” system, they tilt left / right whatever, the retreating blade balances the advancing blades lift to give a perfectly balanced inflite operation. Gyros generally have a VNE of less than 90kts, so this teetering system is fine with that, 100% ok. If gyros were to get to much higher speeds then the rules change, matters like re
  8. Yen......the golden rules.....dont do power push overs, dont introduce purposing, don’t rush your blades ( startup ) Blade flap.......gee how to simplify it, here goes.......at very low rpm as your taxiing to get blades to flying speed, if you rush the blades, the advancing blade generates too much lift to allow the retreating blade to teeter enough to balance that lift, that retreating blade hits it’s stops whilst that advancing blade is still teetering up, then things get nasty. Blades over flex, the power building there is massive, it starts to break things and worse........so d
  9. No...they don’t “stall”.....pull off power to zero airspeed, blades no longer able to sustain current height, machine now vertically descends, keep a tad of rudder to stop rotating, and down you sink ( vert drops ) safe as, but not desired landing procedure, machine will bounce on ground, likely to then roll on ground, plus bend undercarriage etc etc. Mindset is different in a gyro.....you must be saying “ can i take off from there”......you can almost land a gyro anywhere. This mistake by pilots is not uncommon, they’ve landed and realise they’ve got problems getting off again, too short
  10. Auto rotations are a requirement of training, but many, if not all insurance co’s will not cover helo if damages are auto related. So training is up to the last bit before touchdown, its the touchdown bit that student really needs to master, especially when you have low inertia blades. Air speed with exact flare, then settle. Gets the pucker valve working.
  11. A little off topic, but....Yet to find an instructor that will teach full auto rotations to full stop on ground in a helo. Sometimes i wonder if they can actually do it themselves. Most power up 100....200ft AGL, if not higher.
