    “Stalling in circuit” ?????????you’ve got me there, ???

    Was using this as an example of risk in fixed wing aircraft where we are at most risk in the circuit, either power loss on takeoff or overcorrecting turns on landing approach with lack of airspeed. If you know what the risks are associated with your aircraft being aware of them will help avoid getting into strife. Was not inferring that rotorcraft stall in the circuit.

    What is the cause of loss of control whilst airborne?

    What's a power pushover?

    Adding to the explanation by Russ

     

    My understanding is there are two main causes of airborne loss of control in a gyro.

     

    Flat spin with a backslide caused by negative airspeed and no rudder authority and a pushover. High thrust line gyros where the thrust is higher than CofG are more prone to this. I believe most gyro prangs are due to rotor mismanagement on the ground.

     

    Power pushover is generally caused by a pilot with uncontrolled oscillations (porpoising) which causes the rotors to unload. This is where the relative airflow hits the top of the rotor rather than impacting below.  Once unloaded the energy of rotation is lost, rotors are no longer coned up and results in a loss of control. It is also a risk as described by Russ in a steep climb and loss of power. (High risk scenario for all aircraft).

     

    Many accidents early with benson style home build machines were people teaching themselves to fly (a bit like early days of AUF or before). Gyros are no more subject to catastrophic component failure  than any other machine depending on maintenance. In Australia Gyros are used extensively for mustering and many of these machines work 1000+ hours a year. It is not uncommon for many of them to have 5000 - 10,000 hours on them (or more).  My old style high thrustline gyro now has almost 6300 hours on the hobbs and is on its 2nd 2.2l subaru car engine. Did 3 hours of fun flying this weekend in it. Plenty of people criticise anything outside mainstream for reasons I can only speculate. 

     

    Many modern Gyrocopters are well over $200,000 new and are very sophisticated. Like fixed wing and stalling in the circuit, know the risks, know your aircraft, stay current. They are an amazing platform. Training, airmanship, maintenance. Good to go.

     

    Probably a bit off topic now!

    Class E LL5000, would be acceptable.

    Not acceptable in areas where that is ground height or close to it. Plenty of terrain in VIC to NSW corridor puts us very close to or into the dirt at A050. There are some very strong responses being written for submission which speaks to how seriously disturbing the proposal is being viewed in the community.

  4. I don't recall seeing any instructor driving a mercedes. It must be a labor of love. I recently spent time with one who is running 2 aircraft, they are averaging 300 hours a year in total with less than 40 students on the books. They take the time to pre and post brief training flights, time which is not charged for. The tuition charge for test preparation is $80per hour. Flying charge is $200 an hour.

     

    While I was there on each day I saw at least 1 cancellation due to no show or last  minute withdrawal. Tjat impacts a one peron operation

     

    They told me they were exhausted after 5 lessons in a day and I am not surprised. Four hours in a day on an average nav wears me out.

     

    This person like many others is over 75 and unbelievably experienced.

     

    These operators are often in regional areas and there doesn't seembto be any sucession planning probably for a few reasons.

     

    It seems to me that he large commercial operators are romanced by oversight bodies as it allows outsourcing of many functions that they should be responsible for. This in turn increases the cost to consumers as profits take a driving seat. It also means the time and financial costs associated with complience must make smaller opeations evermore unattractive to pursue.

     

    As others have  pointed out there are some bad ones, and remember we can all have a bad day, it must be a tough gig being an instuctor at times.

     

    Most of us will benefit from a bfr if for no other reason but some reassurance that we are going okay. We should celebrate the overwhelmingly positive impact our instructors have on our sport.

  5. I have been told that livestock and roos get confused by a continuous sound like a horn blowing and they can't work out the direction and location of the sound. An intermittent beep beep beep beep (for example) gives them a clearer indication of distance and location of where the sound is coming from, this allows them a better chance of moving away. There are bushies who have a constant beep beep horn they can run at night while traveling and they swear by this. I have tried it by just using the the horn with regular short bursts as I approach and it seems to work. Emus are a different kettle of fish and at times have suicidal tendencies.

     

    Recently tried to clear some roos off a nearby strip, after they refused to move on the first run I did a second just over their heads and they still would not budge, I went and landed elsewhere. When they are in poor condition they are sometimes just too buggered to move.

  6. I am currently mentoring/supporting my 14yo though his RAA theory subjects prior to commencement of flight training. It has been 35+ years since I did the theory myself and have found the process really good for a refresher. Having said that it has highlighted to me how much the questioning style leaves to be desired rather than sensibly actually testing knowledge. It has been like that since I did mine and I thought it may have changed since then but no.

     

    On the matter of BFRs - due to COVID this year I used an instructor I haven't used  previously. The cost was $240 for .5 in my own aircraft with a cup of coffee before hand, I thought that was expensive especially as it was instant. On the last circuit, while completing a no flap simulated engine failure the feed back was its all good full stop here I've seen enough. Later when paying, as I was leaving I accidently grabbed a document summarising the BFR which was being sent to RAA in which it discussed how lousy my rudder control was and that I had received corrective instruction. When I asked if I was going to get the corrective instruction the response was that my rudder control was good and the document is only to show RAA that something had been corrected. I was unhappy that the system must make people feel they need to do that and make stuff up. 

     

    I fully support BFRs and always ask that I am pushed or challenged. I love flying and feel so lucky to have been born in a time and country which allows me to have a hobby like aviating.

  7. There are many options available to get you in the air if its the flying that you are after. If commuting or speed are important then your options go a different direction. Power paragliders, trikes, gliders, gyrocopters are recreational flying machines that will safely get you into the air and can be very inexpensive depending on which way you go.

  8. Old thread but wondering are these thermostasis regulators a common installation or not. Does anyone have a 2nd hand thermostasis regulator for sale or know where I might get one in Australia. 

  9. Lots of great advice here. I'd add a photo of the cockpit of your aircraft and put it up on your big wide screen TV. Lounge chair fly (imagine/pretend) you are flying and practice radio calls with physical movements operating your imaginary controls. Really useful after a lesson for revision. You will look like an idiot to someone who doesn't know what you are doing but helps build familiarity and muscle memory. Go outside and draw a big runway on the ground and walk it. Pretend you are taxying entering backtracking rolling departing and the rejoining for a circuit. Talk it out loud including your calls. I think a lot of circuit training value is lost with the pressure of radio calls. This is what I am doing with my 14yo who is currently learning, he is assisted by his two younger brothers who are also learning simply by association. Effort equals reward in everything. 

    P.S. this is an old pic!

  10. Thinking out loud here about replacing the surge/overflow tank on my gyro with something like this. Currently has a 1.5 litre tank fitted. 1I like the idea of this which is 10 litres and has a fuel level sender. Would be mounted below the seat tank and give a better indicator of fuel remaining than I currently have which is a site tube on the side of the seat which cannot be seen while strapped in. Anyone done anything similar or used this style of tank. Picture flogged from eBay which has many sizes and designs on offer.
