Landing correctly

[Flamin_Squirrel]

I second that ^

 

But the distance to the runway itself can be confusing. I mean usually, the waypoint is center runway, not the edge. How to remedy?

 

You can use your pitch scale in the HUD to get the correct approach angle. Line up with the runway then fly to put the runway halfway between the 0 and -5 pitch lines. That'll be close to the 3 degree slope you need. Then put the VV on the threshold and adjust throttle until the AOA indexer indicates you're on speed.

I second that too.

[Yurgon]

Or.... you take a 'space shuttle flying brick' aproach... :wacko:

 

[...]

- The speed can be at 300 +, apply flaps 1, gear down, this is the pre-brake stage.

[...]

 

That sounds like fun. Can you do that and record a track for our entertainment? :lol:

 

Just one tiny detail: the flaps won't come down at more than ~190kts and will automatically retract if the A-10 goes faster. If you crash on your space shuttle style approach, blame it on that. :thumbup:

I was just about to land after a test mission and i decided to Fraps it to demonstrate how i do the straight in approaches. Nothing fancy, nothing complicated. But it's a 100% success every time with this procedure.

Very nice :thumbup: and it's the same no matter the plane and weight. jst keep your VV on the threshold (or third wire ;)) and AOA in the green.

Overhead break.

Any truth to the braking being calculated on a wet runway causing very inefficient wheel braking?

Braking will be worse in any wheeled vehicle on a wet surface since friction is reduced. Plus the pilot needs to be more careful applying brakes since the surface may not be uniformly wet.

 

An important thing IRL is plant the wheels firmly, not gently. You need to break the surface tension and get the wheel on the runway surface otherwise they can aquaplane, which can generate enough heat to cook the tires.

 

Other than that it probably depends a bit on the weight of the aircraft and surface area of the tires as to precisely how it reacts to water.

 

You probably don't have to worry about any of this in any simulation except maybe reduced friction (ie. less effective braking and possibly aircraft skidding) when it rains.

[Kibblez]

It is also effected by tire pressure. It wasn't a major point, but this was part of flight training back in the day when i had first started flight training.

 

It is directly related to the square root of the tire pressure. According to testing cited by the NTSB (National Transportation Safety Board) the speed at which a normal tire will begin to hydroplane is 10.35 x the square root of the tire pressure. So, if the recommended tire pressure for your vehicle is 36psi, the speed at which you can expect to hydroplane would be 62 mph. Let that tire pressure go down to 25psi and you're hydroplaning speed drops down to 52mph!

Are you referring to the discussion about a year ago?

 

I have no clue if it's implemented in 1.2.0, imho, you don't stop any faster in 1.2.0.

Oh, it's true alright. braking sucks in the wet. I just loaded up a quick test to try it out. Hit the brakes after accelerating a bit and almost did a 360 degree sliding spin.

Side note: Our min required landing distance data IRL for the jet I'm currently flying (CRJ 900) increases by as much as up to 40% for wet runways. All depends on the runway, its gradient, other factors etc. calculated by data provided from dispatch... but just to give you an idea. The actual landing distance doesn't increase as much as the required distance (unless you hydroplane of course), but it can be a significant number, too.

 

Now, consider what an icy, snow-covered runway will do... :P

[ENO]

I was unclear except maybe to dej. What I meant was that when ED crunched the numbers to generate a traction profile for the aircraft- that the figures used for a dry runway in the game are actually emulating wet strip performance irl.

[Corrigan]

Wow, really? So how much faster should we be stopping (on a dry runway)?

[ENO]

Well- if there is any truth to it (which is what I'm wondering) then I suspect a fair margin. I've always been a bit dubious at how horrible our wheel brakes are but then I stumbled upon two pieces of info:

 

1) I was landing too fast

2) this wet runway possibility.

 

I'm getting a bit more confident in my approaches and have been touching down early- fully deploying speed brakes and on most runways I'm able to almost roll to a stop with only a last second partial application of the wheel brakes. Most of this ability came from sliding off way too many runways with every ounce of brake pad I had on the plane turned to dust.

[Corrigan]

Maybe some of our clever members with IRL Hog experience could comment. Is there perhaps any real stopping distance data available?

[Dejjvid]

We've discussed this in another thread. Can't find it now, search function has some development potential when you're on an iPhone..
