How to take off with this plane http://forums.ubi.com/images/smilies/351.gif

#1, dont take off with anything bigger then a 1000lb bomb. #2, dont take off from a stil carrier. Make sure its moving. #3, keep the chawks on, rev up the engine FULL for a few moments. NO FLAPS!!! #4, once you release the chawks, push the stick FORWARD! Get that tail off the deck! #5, once the tail is off, level out and now you can see the carrier. #6 When you see the edge of the deck is comming, full flaps! #7 The moment your off the deck, get those gears up FAST.

So note. Rev up, no flaps. Watch the deck. Full flaps at the end, and gear up once your off. You should be good.

You can take off with the 1600 pounder... just not from an escort carrier... The illustrious might be a challenge form the number one spot also.

From the Lex, you load out 1 1600 pounder. Go to full flaps. Before you throttle up, release chocks and let the plane settle on the deck. After it settles, then re-set chocks.

Go to full throttle and after the engine stabalizes at a steady RPM, release chocks. get the tail up as fast as possble and keep the plane straight. As soon as your gear leaves the deck, raise it and apply gentle back presure.

I've done it easy from a moving carrier, I'll have to try it from a stationary.

I can take off with a 1600 pounder from a stationary carrier no problem. Leaving flaps up as you roll down the deck and then dumping in full flaps as you roll past the edge? That simply defies all logic. You want take-off flaps down BEFORE you remove the chocks. Watch some videos from WWII... Do you ever see a carrier pilot dumping in full flaps just as he lifts off? Nope. They've got takeoff flaps down already, but not full flaps. As soon as they are off the deck, they pull up the gear as quickly as possible. When the gear is up and positive rate of climb has been achieved, then retract flaps. Says the same thing in the Pilot Operating Handbooks.

I know it defies "logic" but logic only applies to the real world. This is IL2 and runs by its own set of rules based in real life.

The rules are that flaps cause drag. In IL2, drag effects you by slowing down. I have found that SPEED is what you want more in IL2, not lift. So the more speed you have, the better your chances of lifting off.

Test it. Start your takeoff run with full flaps. Mark the speed you have the moment your wheels are off the deck. Then do it with flaps up, and then slam them down as you get close to the end of the deck.

I find that with lowering flaps at the end, #1, your going faster, #2, your aircraft is a LOT less prone to stall and roll over, and #3, I can get heavier loads up. Your still using your flaps, but your gaining more speed. It takes a little timing, but it works great. Try it!

Why would you people lower flaps on the take of run?? That's not how they did/do it in RL. With the flaps lowered before the run, they should not be a problem and I can get of a carrier deck as well as anybody that lowers them later. The flaps should add more lift than drag anyway, especially at combat or takeoff settings. All the way down, they give more drag than lift. This is pretty much the way it is in RL too. Besides, real life pilots could develop a bad and dangerous habit if they do this stuff. That's why I prefer to do it the realistic way.

ACtually - LOwereing flaps after accelerating is a technique that has been used by Bush Pilots. Don't know about WWII aircraft IRL though.

P.S. dont forget to use full rich mixture for a little extra power .

First let me preface this by saying that I am a real world pilot. I only fly Cessna 172's, but I fly nonetheless. I agree that there are differences between the real world and this sim.

However, your statement about having faster speed is better than taking off with flaps (with the increased drag) is fundamentally flawed. Here's why. A wing has a higher stall speed when it has less camber (flaps up). The wing on a Cessna 172 will stall at 44 knots with flaps up. With flaps down, that same wing will stall around 33 knots. That means the wing will be able to generate lift with flaps down at a slower speed than it can with flaps up.

In order to conduct a short-field takeoff in a Cessna 172, you put in 10 degrees of flaps, and you hold the brakes until the engine is developing full power. Then you release the brakes. At around 51 knots, you "pop" the plane off the ground but keep the plane in ground effect (flying within a wing-length of the runway) until your speed is a little higher. Than you pitch for best-angle of climb airspeed (which is SLOWER than best rate-of-climb) so that you will have cleared the 50 foot obstacle in the shortest amount of distance.

I've never had a problem taking off from a carrier with takeoff flaps down before releasing chocks. The included training missions even tell you to lower flaps before takeoff. The reason is because that is the BEST WAY to take off in the shortest amount of distance.

Like I said, IL2 some times does not fallow real world.

Im not saying to take off without flaps. Im saying deploy them once you get more speed. Thats all! You made it sound like I was saying your better off without flaps at all!

Now, whats safer in real life. Taking off at 51 knots with full flaps, or taking off at 60 knots with full flaps? Same thing I am doing on the carrier. Getting more speed by dropping flaps later on in the roll. This helps get speed up, and your not "riding a stall" like you would normally do.

This isn't real world. It's Oleg's world. Gibbage is right, if you have flaps up to gain speed, then put them down to take-off once you are in teh air you'll have more success taking off.

This was the ONLY (I repeat ONLY) method I found to get heavy aircraft off of high airfriends. Like the He-111 with 2x Sc2000 or the Ju-87 with the Sc1800. The online map I often played (with the 4 mountians with airports at about 3000M) were natorious for killing loaded pilots. With full flaps down, a loaded He-111 was not able to get enough speed to take off. Dropping the flaps AFTER I got the speed worked, and worked VERY well. Just try it before you say I am wrong. But try it a few times to get the timing of the flaps down just right before you say im full of it, K? What can it hurt other then a few virtual wrecks http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif

I am able to get the SBD3 off of a large carrier with a 1600lb. bomb without doing what Gib said.
I set takeoff flaps, set mixture to 120%, allow it to warm up for a while, then allow it to sit at full throttle for 10 seconds. Then I release the chocks and get the tail raised up as high as I can without striking the prop on the deck. Works like a charm. I get pretty close to the water but haven't smacked it yet!! And my loadout is the heaviest one for the SBD.

11-11-2004, 11:49 AM
Same here, mortoma. I can take off the SBD3 with a 1600lb bomb without any problems without using Gib's method. I'd rather use the more realistic method, especially since it works just fine. What Gib says about high density altitude takeoffs may indeed be true in this sim. But I'm taking off from a carrier, not a mountain.
