Doolittle flight - takeoff

Featured Replies

Has anybody managed to get off of the carrier deck using the recommended settings? After taking a dozen or so swims,:-vuur I finally tried full flaps instead of 1/2 flaps and got off on the first try.:-yellow1The briefing also says to keep the nose higher than normal on the roll but I also can never get the nose to raise at all before rolling off the edge of the deck. The elevators simply aren't effective until you gain some more speed. I'm only making about 50-60 mph as I leave the deck.:-eekA real challenge and a great feeling when you pull it off!:-beerchug

Try this: Set up trim above normal take off setting, Fs2002 implements trim by actually shifting the C of G. More up trim will encourage the nose to lift earlier.Full power under brakes, two notches flap and hold on brakes. Let go brakes and keep all control inputs minimum - rudder input in particular creates drag and delays acceleration.Try a little less fuel than max recommended for carrier take off. Expect slight altitude drop after leaving carrier end. Nurse aircraft into level attitude then slow climb until airspeed sufficient for higher climb rate. Clean up gear and flaps soon as practical.This is UNOFFICIAL and could result in an early bath!Rob YoungMAAM-sim

I think I know what your problem is. Open the weather menu and see what the wind is showing. If you do not have a 50 knot headwind from 345 degrees, which is exactly what the Doolittle Raiders had, you will never get off the deck safely - and neither would they have!If you are flying with real weather or something else has altered the weather from the wx file that came with the flight, you are doomed to failure. That 50 knots was a combination of the Hornet's headway, and a brisk wind. If your ASI isn't registering 57 mph with the brakes set, that's a dead give-away that the wind is not there.If you have the headwind, and follow the briefing techniques exactly, you should lose no more than 30 feet, with no further adjustments.Bill Rambow MAAM-SIM - Rambow, Visser, Banting, and Younghttp://www.fssupport.com/maam_sim/maamsim_logo.gif

After years of FS Carrier Ops on the Zone -- only a few words. Follow the advise given. Taking off is optional. Landing is mandatory. The B-25's didn't have to land on a carrier. Thank God. It is a marvel they took off at all.Not sure if the flight model of the B-25 holds the bomb "load-out." The bays are empty. No bombs that I can see. That should make it much easier. I can do it (see pic somewhere below) But, it is by the skin of your teeth. No sudden movements. Everything must be smooth. Flaps are a drag to accelation. So is the rudder. You need speed!! The air under your wings. Deploy the flaps just before going over the edge. Pull your gear up immediately. Heck, you won't need them if you hit the water. You may need them later. You will notice the airspeed pick up as the air drag decreases.Just some words from an old GZR with many hours in CFS1 and CFS2 in combat on the Zone.Frenchy -- out.

Frenchy, take another look in the bomb bay. There are six 250 pounders hanging in the racks.http://www.fssupport.com/maam_sim/bombs.jpgBTW, 'BT's bombs are not fiberglass replicas - they are real 250's discovered abandoned in a Pennsylvania factory. These, along with the armor cheek plates you see on the nose, the armored bulkhead behind the bombardier's seat, and elsewhere, along with eight real Browning "Ma Duece" machine guns with their ammo make this one of, if not THE heaviest B-25 still flying today.We have room for a couple more bombs on the shackles, if you happen to have a pair in your garden shed. :-)Incidentally, guys, I have set a full fuel load for this flight to give you a challenge that approximates the one 61 years ago this April. Follow the briefng instructions to get rid of some of that fuel and the wind before you make your approach at KSFO.

Good God Almighty. I sniffed around up there looking for the "load out". Going to go back up again and look. Really glad to see that. Full fuel -- nice. I never dump fuel in combat unless 100% absolutely necessary for survival of the aircraft. Question? -- (this isn't a fair question) How does one drop the bombs? Arrrrggh. Frenchy -- go back to CFS2. This "work of art" has a lot of potential. A whole lot. You guys done good. Thank you for all your hard work. It is most appreciated.Frenchy -- out.

Bill,After loading the John C. Stennis carrier, I selected the flight according to the instructions, and got off the deck just fine. I flew a short pattern and brought her around for a deck landing as well. Got her down on the deck and stopped fairly quickly, even with the fuel and bomb load! Indicated airspeed was around 92mph on touchdown, which would only be about 50mph onto the deck.Sweet!

BINGO!I had the "taxi winds control" option checked in FSUIPC that keeps the winds at no more than 5 knots while on the ground.Now I'm impressed that I was able to launch at all even with full flaps!:-lol
