Ok heres the problem,
im trying to sucessfully land my airplane i get it on the air and press "G" to retrieve the landing gear. I make a couple of air tricks an all that crap then when i whan to land i press "G" to place out the landing gear and the landing gear doesnt work .
Is there another button to put the landing gear down?
-
It sounds like you are flying too fast to lower it. Gear does not come down if your overspeed. Also if you forget to take it up it will break when you go fast.
Get the speed down to around 150 or lower and try again.

THANKS i did just that and it worked!!!!
-
the number is actually 200mph for all planes before you can get the gear down, but if your doing 200mph and put the gear down and accelerate theres a chance it will break off
just thought u shud know the absolute limit, might come in handy in a situation
-
160 is the magic number for most aircraft.

Max speed for gear is usually between 170 and 180 mph. An exception being the F4Us, as they use it as "airbrake" and can lower gear at speeds up to 350 mph.
-
what was so special about the f4u gear that it didnt break off at those speeds?
-
Hmmm..just tested a bunch of aircraft offline.
All seem to have the magic number of 200 mph to lower gear, although if you sustain that speed they eventually rip off, so you need to keep decelerating if you lower them at that speed.
The difference of course was the F4U, I was able to lower the gear at 390+ mph with no trouble.
Porkfrog, The F4U used it's landing gear as a speed/dive brake as well, hence the ability to lower them at higher airspeeds. They are pretty beefy landing gear.
Funny, I wonder why I had 160 mph so imbedded in my tiny melon for so long?

The F4u gear is very tough - dare I say tough enough to survive a ground loop! ;)
Schatzi has the real answer, they can be used as an air brake, although I must admit to not knowing if the any of the wheel well fairings have been designed with this secondary use in mind.

RTR - Some planes, Spits for example, require your speed to be less than 160 to drop flaps. Maybe that's why you had 160 on the brain.

Probably because it is a sensible maximum to use. - Its trhe figure I work to to! I just tried a hurricane and got the gear down at 200 then a second or too later it was whisked away without even time for the metal to creak!
I am not in favour of dropping gear for any other purpose except landing (F4u excepted). A side slip and cranking in some G turns will do a far better job at scrubbing off speed, so on that count, 1cemanVS why drop gear at its maximum limit ?
Advice to joseph_v was to make sure he was likely to operate the gear at a safe speed and so be successful in getting it down whatever he was flying

Well there's rather a few scenarios
-In an engine-out situation returning to base, you have not correctly judged your AoA and are too fast coming into the runway.
-Overshoots
-Caught too fast on the deck in a low speed performer, your instinct tells you that you can get off a good shot if you just come around fast enough.
Gear down + rudder will bleed E faster than rudder alone, and sometimes you do not want to pull heavy g manuevers in bleeding airspeed (such as forcing overshoot with intent to kill). Hey even if the gear rips off its all good. Belly landings :aok

Good Grief. In either of the first two you can't fly well if you need gear drag as well in a desparate attempt to drop from 200mph due to a hopelessly reckless approach. In some a/c you will not even be slow enough to drop flaps for landing! - No dispute that gear adds drag but it is relatively small compared to other means
Check out the best corner speed of your aircraft - If it is above 200 why try to slow below that for your turn. Remember your "too fast" scenario here is the max speed you can drop gear at!
Just chopping the throttle to force an overshoot with some yaw will work I think you are overating the amount of drag you get from the gear over and above what you get from other actions.

im not saying you have to lower your gear at 200, but its good to know that u can get your gear down at 200 if an emergency arises, i generally bring my gear down at 200 with the intent on slowing down further, never had anything rip off and means i can approach the runway quicker if i need to...thats all

"I am not in favour of dropping gear for any other purpose except landing"
One wildcard is the Me163, which has a landing skid rather than landing gear. I have landed with the skid, and without, and I can't tell the difference; in both cases the aircraft comes to rest much more smoothly than I expect a real Me163, landing on concrete, would have done.
The Ju87 Stuka and D3A1 Val have fixed landing gear. According to Soda's wonderful article on the Ju87, the landing gear rips off at 500mph, leaving the aircraft slightly faster but otherwise unaffected!
The C47 has semi-recessed landing gear that pokes out of the nacelles a little bit. I have never belly-landed a C47.
I drop gear at 190mph, but only if I am slowing down. Because I can.
-
I believe the gear on an f4u is designed to be an airbrake. The gear panels are facing flat against the wind when lowered to slow you quickly.
If you doubt the validity of their use in a fight, try going up against blukitty in a hog sometime. You WILL believe.
-
The gear on the F4U was reinforced for carrier landings and use in dive bombing. They have flat panels on the front of them to help create drag. I have more than once forced an over shoot by adding full flap and dropping gear in a slow fight then cleaning up in a hurry to get a shot off, it works very effectively as not many planes can stay afloat as slow as the hog can. (don't try against a zeke :p )
S!
Rocket
p.s. I always use them in the traditional role of dive bombing to help keep me slower longer on steep decents. Keeps a more stable platform to drop bombs from IMO. Once the bombs are gone, clean up and zoom out as the hog will accel quickly in the dive.

I'm not sure what you mean by hopelessly reckless. If you have been gliding without an engine for a while back to base, you are certainly going to overestimate to make sure you at least can make it to the runway. In landing on a carrier in such a situation, overestimation is even more important. You may find yourself crossing the threshold of the runway/flight deck at 200mph or so. Why not drop the gear at its earliest possible time, so you, in turn, can plop down safely at the earliest possible time?
And how is forcing an overshoot considered "reckless"?

Which aircraft are these? I'm not doubting you, I'm just curious. I'm pretty sure I've attempted a landing with every aircraft in the game, and I can't remember one that I couldn't drop flaps in.

Every bit helps, if the situation calls for it. No point in not taking advantage of something positive your aircraft can provide you with.

I may be overrating the amount of drag, but, again, every bit helps. Obviously yaw will work better, but in situations where you know that once the bogey overshoots you can knock him out of the sky, the less yaw the better. Your nose will be in a better position to take that shot.

The Ki-84 can't drop landing gear above 160mph. Perhaps you fly the Ki-84 a lot.

Trotter,
Remember the context of my comments relates to dropping gear at 200
If you have ever arrived at the threshold of a CV with 200 on the clock I reckon you will drop the entire aircraft! - There is no landing that I can think of where you even want to be 200mph at the final stages. With so many alternative means of getting speed off in good time, having to drop gear at 200mph is in my opinion reckless! - In your opinion it isn't, so fly as you fancy!
At 200 you will not be able to drop flaps in most british aircraft. You are taking my comment out of context as all aircraft with flaps will be able to drop them providing you are at an acceptable speed for type. Alternatively your comment "I'm pretty sure I've attempted a landing with every aircraft in the game" suggesting you can drop flaps at 200 with all is rubbish. Try any of the Spits, any Hurricane or Typhoon
You won't ever need to drop gear at 200 if your flying is half decent, why risk wrecking your gear ? - But if you need to carry on!
By the time a bogey is even level with you in an overshoot you should have been done trying to slow down! - But if you need more time to stop yaw then I suppose you do!
At the end of the day it's a game and from a gamers point of view, anything goes if it works. Perhaps I have allowed the thought that this is more than a mere game. But if the attitude of players gets to being that they prepared to wreck their landing gear just to try for a better chance of a kill then I am sorry, they certainly are not playing for the same reasons I do, so good luck to you.
-
I think you have misunderstood what I am saying. I am referring to the specific situation of approaching a landing when your engine is non-operational. The last thing you want to do in that situation is come up short of the runway, so, I usually over-compensate and purposefully come in a little faster than I should. I agree with you that no landing with a working engine should be in its final stages at around 200mph.
When you said that there are some aircraft that won't ever allow deployment of flaps in the landing, I thought you were referring to all landings, not just the "200mph" variety we had been discussing. Yes you're absolutely correct that some aircraft won't deploy flaps at that speed.
But anyway this is getting way off topic.
Where I still disagree with you is you assuming that dropping the gear in a risky situation just to get a kill somehow indicates a different breed of flyer than one who wants to preserve the gear intact. To me, this is the same thing- except for one wants another kill, and the other wants to make absolutely sure that they can land their kills. And besides, you seem very confident in your landing abilities; a belly landing should be no problem for you. :aok

"a belly landing should be no problem for you".
Quite So Trotter, but too many of 'em unfortnately as I still remember doing them!.
Have a good Christmas :cool: :aok
