brakes too weak
« on: June 21, 2005, 02:17:40 AM »
I have read more than once of P-38 pilots who held their planes with their toe brakes with the engines revved to T/O power. I've tried to hold the P-38 and it starts moving at fairly low power, even with full fuel tanks and a full ordinance load. A moving plane should not be easy to stop with brakes, but a stationary, fully loaded plane with full brakes should not move so easily.

Best regards,

Cement

I have a hard time slowing down planes after landing since I try to land with wheels down usually.  I can get it to about 50-25MPH and the plane doesn't want to get very much slower.  This is using the keyboard for brakes if that has anything to do with it.

nirvana,

 empirically speaking, repeatedly engaging wheel brakes at intervals slow the plane down a lot faster than just holding the bakes down.

 When brakes are held down but the plane still moves down the runway, it means the wheels are virtually skidding across the runway rather than rolling, because the traction is not enough to bring it to a complete stop.  

 Therefore, by repeatedly engaging brakes, you force a 'grip' to the surface each time you press down the brake. This gives out a lot more traction than just holding the brake down and letting it skid and drag across the runway.

Gear is over-rated!  I just come in full speed and slide in sideways on my belly! :D

ha ha!  That's true, Ive had to resort to that a lot with the P-38 when I'm coming in with a dead engine.

It seems when your engines are out it takes for ever to stop when u land on runway.  Almost seems like they have hydraulics implemented in the game but never told us,lol.

Try this, get your car up to 80mph on a deserted country road. Now throw it into reverse and punch the gas. What's gonna happen?

Same thing applied to a piston driven aircraft.  Even if all you did was revese the pitch on the props the stresses would be to much.

I can land and stop most of the planes I fly using only 50% of the runway. If your having trouble stopping it means you are comming in to fast.  Kw is right pumping the breaks is the best approach.

Kw or anyone else, would adjusting the key repeat rate in the bios help guys out with things like this? It doesn't apply to me as I have pedals with toe breaks. This was a thought I had the other day while talking to someone regarding trim. They were using the keybooard and having difficulties.

He has a point. I've got training videos showing them running up and the planes staying put. Granted some can't run all the way up or the tail will start hopping out of control. Currently you can start rolling with even small amounts of power.

Ok, is this "wheels skidding on the pavement" thing moduled or a matter of any excuse is better than none? I remember when the spit was almost impossible to take off with and having it explained as torc effects etc. In the end, the problem was that the wing of the spit was dragging the ground in the takeoff module.

So tell me trufully, are the wheels skidding on the pavement really moduled?

Don't know about skidding tires, but the brakes don't even hold a stationary B-24 with full fuel load, and full ordinance. I suppose that the current brake setup is some sort of trade-off to minimize coding requirements.

Best regards.
