Rex owner Lim Kim Hai is worth billions so I am guessing he already said "Yeah, nah. No money from me now off you go".

If that is correct, our government could say to Lim Kim Hai, that we buy Rex off him for an advantageous price. Then the Government would have all of the routes that were bugbears for the large airlines, (the regional routes). It could service them at a loss, getting levies from the states per pax carried? It could also do East West (Sunstate) and also use Rex on money for jam routes to keep any major airline honest!

(Only my 2 cents worth)

That seems to be it in black and white.......

How about this?

 

Let's place our plane on that treadmill and see what happens. If the wheels were perfect - that is, there is no friction in the bearings (and no deformation of the wheels as they spin) - then something interesting happens. When we turn on the treadmill, the plane stays stationary on its own. The wheels simply spin along the track, and impart no force to the plane. If you had a car with frictionless axles, and you disconnected the whole drive train, the same thing would happen to your car.

 

The only reason that a plane or a car moves backwards on a treadmill is that the wheels are somehow partially locked to the axles. In a plane, this is because of minor friction in the bearings. In a car, it's because of the drive train. If you want the car to stay still, you have to turn the drive train at the proper speed. If you want the plane to stay still, you have to overcome the minor bearing friction. And again, since friction does not change with speed, you don't have to exert any more force at higher speeds. If you run the treadmill at 5mph and turn on the plane's engines just slightly, they will provide enough thrust, pushing against the air, to keep the plane still. If you then increase the treadmill speed to 500 mph, you won't need to adjust the throttle on the airplane - it will remain stationary. That's because it's seeing the same frictional force that it was at 5mph. Thus, it doesn't matter how fast the treadmill is moving - if the pilot does not want to remain stationary, then he won't. It only uses the very first bit of power from the engines to keep the plane stationary. As the throttle is increased from that point, it moves forward just as it would on any other runway. It's pushing against the stationary air!

 

If you don't believe me, imagine this (or even try it at home): you're standing on a skateboard on a treadmill. You hold onto the handrails of the treadmill and turn it on. Of course, you'll remain stationary (relative to the ground). In fact, you only need to use a very light touch to stay stationary - perhaps a few fingers pressed against the handrails. Crank up the treadmill speed as high as you like. You'll still only need the same light touch to remain stationary. At any time you like, you can move forward - closer to the treadmill console - by simple pulling on the handrails. If you had a jet engine, or super-strong hairdryer, you could use this to propel yourself forward instead of holding onto the handrails. In fact, if you're really careful, you might be able to do this at home with a skateboard and a leafbower, but I doubt you'll have a sensitive enough control of your leafblower thrust to get yourself to remain stationary.

 

So you see (oh please tell me you see), the conveyor operator cannot force the plane to remain stationary. And if the plane isn't stationary, it can take off.

 

There's a dedicated website for this!

 

Airplane on a Treadmill

The question is NOT asking you to insert heat, friction against treadmills, etc!

It is asking you to"HYPOTHETICALLY" accept that the "CONVEYOR BELT" is perfect and can maintain the exact speed of the plane's momentum even under changes to forward or backward movement.Then, the plane will NOT take off!

Take the analogy of the wheel brakes being on and irregardless of whether the propeller is at full speed, full pitch or just idling, the plane will NOT take off! (unless the brake is released)

In real life, there is no perfection and "hypothetical". Natural forces come into play and the plane will take off!

It's quite simple. The aircraft is not anchored to the runway. The air that it is in is stationary (assuming nil wind). The propeller will pull the aircraft forward through the air. The aircraft will move forward as usual but the wheels will be turning twice as fast as normal because the runway is moving backwards.

 

The runway could be going backwards at light speed and assuming the wheels have friction-less bearing the plane will still fly.

The conveyor will increase it's backwards movement to match the plane's forward movement, so the plane is still not moving and will not fly.

(This conveyor has a control system that tracks the plane speed and tunes the speed of the conveyor to be exactly the same (but in the opposite direction). Can the plane take off?"

Joew49, I don't know how as a pensioner you can afford to save to buy an aircraft. As a pensioner myself I find it hard to save to buy toilet paper.

My Mum passed away in December and I stand to receive a small inheritance, which, with the few dollars that i have saved should be enough to do the things that I need. However, as the AU$Dollar is falling through the floor I may have to wait for better times, Mate!

Put the Donate button or first class thing back up again..I will throw some money at it and I am sure a lot of others will....maybe also its time to think about a subscription arrangement...setup a paypal for say 10 bucks a year with the recurring feature or something like that for everyone. I donate to a few via patreon and thats US$1.00 per month via paypal and that works well for them to keep content coming

1/

Ian perhaps consider going wider to the whole aviation community via a crowd funding organisation. Us members can help make that fund request "go viral" posting it to all the existing aviation media be it online FB, Instagram print media orgs etc and to flying organisations such as AOPA, SAAA, RAAus etc. That's a lot of people I am sure don't know about the site.

2/

With some of the funds place ads in aviation media to gain new members, site awareness benefits etc.

3/

Charge members an annual fee equal to a magazine subscription or part thereof. ($20?)

Offer a 3 month trial fee of $5.

 

4/

See if you can become a spot/ click fee agent for sales on all/any aviation shops, products (EFB memberships) /organisation and list links on your site. Don't know how hard this is to set up.

 

I am happy to contribute a membership fee or donation.

 

Keep your chin up and keep networking out to that big ocean of abundance, it usually bring rewards and support as you can see from this thread. .

 

Regards

""Charge members an annual fee equal to a magazine subscription or part thereof. ($20?)"" Unfortunately it needs to be more than that! I would envisage $10 per month, plus maintain the gold members! Those are people with spare cash the they can afford and which some of us struggle to.

Ian, I've been thinking for some time about this. Can I still kick in and become a "first class" member?

 

Mark's idea is good too. Times will be a bit tougher for everyone but I reckon you'll find people would go for an annual subscription if it helps keep the site afloat.

Yes, How about a $10 a month subscription and the donation as a first class member with a "minimum" ???

I don't mind to "donating" as a first class member. I can afford the $50.00 as a pensioner, but , would be hard pressed to donate much more. I need to save to buy an aircraft and have flying lessons to have an RAAus certificate, to be able to fly the same aircraft.

I am not a computer genius but would distributed computing work? i mean, there are all these computer times of members that could be used for free?

What nasty piece of work you are? Angry little man by the looks of things! When you've worked 10 years in the EMS field & seem the stupidity of people breaking the gazetted laws as well as natural law then you might grow a brain!

Ignore for you!

Why, Mr Maktuk, how easily the veneer of civility has cracked! When you criticise other people it’s ok, but as soon as someone dares to criticise you, the wheels fall off!

I leave you with a fine quote suitable for this occasion: Laws are made for the guidance of wise men and blind obedience by fools!

Dear Mr Maktuk, did you thank all of the people who died just so you can fly relatively safely?

You are running down people, calling them names, and for what reason?

Is it to get your name up in lights, is it because you are on some power trip? I am sure that you’d like to be the boss of CASA and bring some more rules to make the life of others hard!

What happened to minding your own business?

I am afraid, the likes of you are the reason that I haven’t built and flown my own aircraft yet.

Somebody mentioned Gus Grissom, in a previous quote. I remember the exact day when he died in an engineer designed and proven flying machine and could also name a vast number of others that met their end the same way.

Just a little hint for you: If you have nothing good to say about someone, don’t say anything!
