Nosewheel goes haywire in high speed runway landings

[TeeJay82]

As i was training on safer landings... i encountered trouble with the nosewheel... as the track shows it goes completly haywire... if i pull back on the stick... it stabilises.. if i push it forward... the wheel breaks but only with brakes applied.... now.. should it not be opposite at least? as a wheel get lifted it should lose traction and hence become unstable.. and forcing it to the ground should give it more traction?!? Or are my understanding of physics completly off? :P

I cannot view the track right now. But, most aircraft use a shimmy dampener on the nose wheel so it doesn't shake like hell. When it goes bad, the wheel will shake when it is under a load at high speed. The more weight you put on the wheel, the more shaking it will do. This can be a very violent event in a small aircraft.

Good practice would be to ease on to the nose wheel at a slow speed. I try to ride the main wheels only in the shark. It will slow down faster on landing with backpressure on the cycling to hold the nose off while holding the brakes.

Mi-8/17 (IRL) will do this sometimes if you land too fast and not perfectly straight, just add some power to get the nose wheel off the ground, slow down a little bit, and put it down again.

From what I recall the manual said that the max rolling landing speed is around 40km/h. The shaking will occur because the nosewheel is free-spinning and can't be controlled like the A-10's.

Aha.. ok ty for your time gents :)

80 km/h :)

Thanks for the correction, I rarely do rolling landings.
