APPR mode uses parking brake?

So I recently learnt that apparently the break button is actually the parking break. Wouldn’t that mean that APPR mode is using the parking break since it gets turned on automatically after landing?

I mean, I guess it would. I don’t really see how you could designate it as the “parking brake” since it’s used for slowing/stopping the aircraft in general.

The APPR uses the brake, because… how else will you stop without using your device? I usually turned APPR off 3 miles out.

Apparently IF’s insta account replied to someone’s concern about the change of the brake location by stating it’s the parking break.

Yes, APPR uses the park break, but because that’s the only option. When you pull down on the rudder (currently, progressive braking is being worked on) it enables the parking break still. So yes, it does, but only because it has to.

Actually I hate the rudder brake thing. Sure that is a good way to brake and rudder at the same time, but having to grab the rudder when braking can make me go off the runway

That’s one of the reasons why the nose gets slammed to the ground when using APPR , the parking brakes are too strong , it would be nice if parking brakes wouldn’t be set automatically with APPR .

We don’t have any other brake in IF than a parking brake. Just as @KaiM and others mentioned, we use our parking brake for breaking, cause it’s all we have.
And yes, APPR mode applies the (parking)brake after touch down.

It’s not pretty, but we manage…

We do have a feature request for variable breaking though. See here.

I agree. Most of the time I turn it of on short final

There is no need for parking brakes on touchdown , you can use the thrust reverser to slow down , sometimes I manage to disengage the parking brakes just after touchdown and it makes a much smoother landing .

IF physics issue, but thrust reversers don’t really help with breaking apparently

Right now brake in IF apparently works as both brake and parking brake.

In real life autoland doesn’t trigger autobrake after touchdown. But based on what you said, IF might integrate braking into the autoland system.

Well it is more realistic that way. When I did a flight lesson in a Cessna 172 that was one of the harder things, you use the toe breaks, and each break pedal controlled that sides breaks independently, so it was actually really easy to shoot your self off the runway. Not sure how that works on airliners and stuff, I know they use toe breaks to, but that’s totally how it works on small planes. 🤷🏻‍♂️

Airliners use thrust reversers and aero breaks for a lot of there stopping power, depending on runway, weight, etc, they will go down to like 70kts before ever touching breaks, because of you touch down at 140kts and slam the breaks you risk significantly damaging the tires, and breaks, at worst you run the risk of a fire…

The only way to fix that is by disengaging the brake once it’s applied and disconnect the AP and reverse that’s how I used to do it

Yep your right but most time 60KT is the speed they manually brake the stow the reverses at 70kt and some times slower

Turbojets have autobrakes and pilots will set it to the level they need before landing under most circumstances.

It really depends on SOP. I can’t say for all but I’ve read some airlines’ SOP for 737 that 80kts for reverse to idle, and disengage autobrake when close to taxi speed.

That’s not the only problem though. If I’m holding the rudder already to the left or right to align on the runway, sliding down might not register so I have to release the rudder the break

I usually break with the rudder button. when you slide the rudderbutton down, its also used as a brake. asbI have my right thumb on the rudder anyways when landing, for me its the easiest way to brake. as I only use appr to establish on the ILS and usually don’t land with it, I’m actually not sure if the brake gets activated automatically
