Brakes

Featured Replies

Hi all,

Just downloaded and installed the Learjet and I have a strange issue.

When landing on touchdown full braking is automatically applied, causing some very short landing distances.

The red brakes box in fsx is also highlighted.

As far as I was aware the Learjet does not have autobrakes.

This also happens if I am performing an aborted takeoff and close the throttles at speed on takeoff.

Can anybody help?

Kind regards

Greg

Hello Greg,

First I'd check to make sure you don't have the parking brake set.

Second, you didn't say what sim you are using, or if you use FSUIPC, but often there are usually  'REVERSE' check boxes associated with brake controller assignments that typically need to be checked.

Hi Al,

Thank you for getting back to me.

Definitely don’t have the parking brake set. I can for example taxi, get to the runway, accelerate to 100kts and as soon as I idle it applies the brakes.

Im using FSX and only use the free version of FSUIPC.

This is the only aircraft I have this issue with.

Kind regards 

Greg

Have you been flying a plane which DOES have autobrakes prior to using the Lear? Or pehaps have a default flight set with an autobrake-equipped plane (with autobrake selected?).

Just throwing possibly dumb questions out there to maybe help the thought processes..

Since loading the sim I have only loaded the Learjet. 

I also tried loading the default FSX trike too and have the same result.

Kind regards

What controls are you using - stick, yoke, quadrant, mouse? etc? I'm out of ideas apart from a recalibration of the peripherals.

Good luck!

Only a stick, this is really strange as all my other aircraft default and payware are working fine.

By this do you mean you loaded the Trike and then switched to the Lear?

If so, at this point I would try uninstalling and then reinstalling the Lear.

Hi Al,

I’ll give that a go.

Issue seems resolved after reinstall 🙂

How do the emergency brakes work (red lever) or are they not implemented?

Good to hear you got things working.

Well, you should be able to move the red emergency brake lever up and down using the left and right mouse buttons, but apparently that's about it as currently implemented.

I checked and there is an Lvar (variable) that represents the position of the emergency brake handle so I suppose we could write a Lua script to activate the sims 'normal' a/c brake system as if the rudder pedals toe brakes where being applied. For example, the . (period) is the sim default key for applying brakes. So perhaps a script could be used to have that key also move the emergency brake handle. Not sure what the real benefit of that would be, however.

As I recall,  in the real a/c the emergency brake system uses air pressure instead of the hydraulics used by the regular brake system.

OK, couldn't resist, so wrote two tiny (one line!) Lua scripts so that when you press the period key the brakes are applied as normal, but also the Lear's emergency brake lever is activated; and when you release the period key, the brakes go off and the emergency brake handle goes back to off. The typical rudder pedal toe brakes are not effected by these scripts.

As always, to run the scripts you need a registered copy of FSUIPC. Setting things up will also require editing the FSUIPC.ini file with a text editor just a little bit since the period key is now used to both activate the scripts and also the normal sim brake system.

I'm still not convinced there is much benefit to all this, but if there is interest by 'brake aficionados' I'll be glad to post the necessary info here.

Hi Al,

Or anyone - since we're having the brake discussion...

I don't use Rudder Pedals since they just don't work with my desk...

In the past I've just used two buttons on my throttle for brakes - left and right - but they don't have any granularity - simply on or off... While not as much of a problem with the Lear - since it has "anti-skid" - other aircraft I fly simply lock their wheels and drag them down the runway... Even with the Lear - I desired more granularity... 

So - then I had an extra axis on my joystick - I decided to try and use that for both brakes - so I could gradually apply them progressively as I slowed down - worked well too - except it can't handle differential braking needed sometimes in sharp turns...

The issue - is both these functions seem mutually exclusive - if you use an axis for brakes you the buttons stop working...

Any thoughts on how I could get the best of both worlds - with two buttons and one axis ?

Thanks...

Regards,
Scott

FWIW as I currently don't have any rudder pedals, only the proportional rocker switch on the throttle of my TM HOTAS X, I allocated one of the hotas buttons to toggling anti-skid. The trigger on the joystick activates the brakes. I would never want to intentionally lock up the wheels so I may as well have anti-skid active for any and all aircraft in my virtual hangar :wink:.

IIRC I can apply rudder deflection and then pull the trigger to get differential braking, or just use the number pad keys. Agreed, they're just on/off, but at least the wheels don't lock.

Scott -- check email. Sent you an 'experimental' Lua script to try.
