Hi,

When i land with a 737-400 for example. I use the reverse thrust, spoilers and maybe some breaks.
What is the proper way to land in any commercial aircraft, because i find using the reverse thrust and spoilers not enough, and when i add the breaks it is sharp. Im landing at approx. 130

Any tips or advisorys.

thanks as usual
Jimbo

I believe you go reverse, which the spoilers then extend and below 80kts you use manual breaking (also I

Landing breaking

autobreaks

I think you mean braking & autobrakes. Breaking has a completely different meaning & involves damaging something.

On landing you will usually have full flap - so on touchdown go to reverse thrust full - spoilers -

For a dry runway, use Autobrake 1.  Full spoiler and reverse thrust should be more than enough.  You can stop the 737 in like 2,000 ft with the proper config.  Below 60 kts, spoilers retracted, idle thrust.  Begin flap retraction.  Turn off autobrake at your discretion.

Hagar, i changed the name for you. Im from up north so please excuse me...

if your saying your coming in too fast, try using lots of trim, that slows the aircraft down at gets you at the proper angle to land, make sure you've got full flaps. A few hundred yards before the thresholdstart to ease back power. ->if this has no effect pull the nose up a tad more, ->if you stall, add a touch more power (should be at around 51 on the main engine gauge)

only use spoilers incrementally, i.e, if you suddenly need to loose speed and altitude, using these on approach at a low altitude can end in disaster often enough.

you really should use approach hold, this'll get this absolutely perfect for you. then at a hundred foot, turn off the autothrottle, then hit z, cut the power and flare, once your on the ground brake then hit F2 if your still fast, (spoilers should deploy automatically anyway)

hope ive helped
will

oh one more thing, even if you've just turned off the autopilot after an IAS Hold, the autothrottles still continue to be armed, these MUST be turned off, otherwise the plane will be a bitch to slow down, and will rapidly accelerate the second the break is released. Try to set the autothrottle arm/disarm key to an easily accessible/memorable key like ESC, ENTER, BACKSPACE, OR SPACE.

Hey jimbo, don't put your self down for being up north!!!! I too am from sheffield (near dinnington if you know it) and have this debate with my Birmingham Uni flat mates almost everyday, they're from london and seem to put 'r's after every 'a'! if that makes sense. They seem to say grarss instead of grass and grarph instead of graph. We are the ones speaking properly, we dont add letters here and there to try and sound posh, we tell it as it is! UP THE NORTHENERS!!!!!!!!!!! I think Commoner will back us up on this one if he gets wind of this message!

Just getting the hang of these semi-automated approaches, but one thing I've learned is: if you're using auto. thrust on approach, you've gotta pull your joystick (or keyboard) throttle down to idle, so when you turn off the AP (including autothrottle) at touchdown, then apply and release reverse thrust, it won't start speeding up again. If you have auto braking, use it- it'll usually do a smoother job than you can.
 If you're not using autoland (many aircraft don't have it), you might just be landing long. Using the ILS or a GPS approach won't take you
all the way to the runway, unless you have autoland, so you may be too high "over the fence", which uses up a lot of runway. In a big jet, you should be flaring before the numbers, and touching down on the numbers or just after.
As far as spoilers/slats go, I believe they're not meant to be used on approach, but rather are armed then deployed automatically when reverse thrust is applied. Maybe in a dire emergency they could be used in flight, but normally if you have full flaps and the right pitch and power settings, you should be coming in plenty slow enough, without too high a sink rate.

i think jr pilot is right

I'm not sure if FS models this or not. In real life, autobrakes provide a set level of deceleration for each setting, not a set level of braking force. As a result, you don't slow any faster by using reverse thrust, it's just the brakes don't work as hard. Of course if you add so much reverse that you exceed the deceleration setting of the autobrake, then the brakes won't be doing anything.

In real life, very rarely is full reverse used...it's quite loud and causes a lot of vibration which scares pax. Also full reverse tends to kick up stuff which is then sucked into the engine...not good.

Also in real life, reverse is set to idle or you go back to normal thrust when below 60-70 knots. This goes back to the ingestion of foreign objects, which is bad for the blades.
