Nealius Posted March 30, 2019 Posted March 30, 2019 So, I know AB usage on takeoffs is prohibited due to asymmetric thrust issues, but is lighting the cans at the end of the cat shot okay realistically? I find that the Tomcat struggles to get airborne with a MIL power cat shot, and drops a good 20' or so once off the deck even with a GW as low as 52,000lbs, so I always have to use AB to avoid skimming the water.
Sadist_Cain Posted March 30, 2019 Posted March 30, 2019 I recall someone saying that take offs with afterburner 'depends on who's watching' lol On a tangent are you sure you're trimming enough for take off? I find it to be very nose happy without enough trim which causes it to drop off the end of the boat.
Possum Posted March 30, 2019 Posted March 30, 2019 You can light them at the end of the cat shot. At night, the deck crew appreciated AB full flap climb.
Nealius Posted March 30, 2019 Author Posted March 30, 2019 Cool. What trim settings should be used? I don't recall seeing any specific trim settings like the Hornet, but I probably just overlooked them. I've been taking off with whatever automatic trim the plane gives me with full flaps, which looks to be about 2-3 NU or so.
Possum Posted March 30, 2019 Posted March 30, 2019 I think it’s supposed to be 0/0/0 for trim, but I don’t remember for sure.
viper2097 Posted March 30, 2019 Posted March 30, 2019 IIRC the trim depends on the COG and should be somewhere between 5 and 9. There is a table in the NATOPS. Also I don't have a problem takeing off mil with even 6 phoenix on the turkey. Just pull the stick have way back in the middle of the cat while launching. When airborne, check the horizontal and vertical speed and trim accordingly. Steam user - Youtube I am for quality over quantity in DCS modules
Sadist_Cain Posted March 30, 2019 Posted March 30, 2019 I think it’s supposed to be 0/0/0 for trim, but I don’t remember for sure. That's what it has you doing in the startup and how I've been doing it, much less horrifying. Follow with a 10° to 15° climb out and bobs your uncle. there's a shiny graph in the natops with the CG and whatnot but I'll be damned with that
Nealius Posted March 30, 2019 Author Posted March 30, 2019 What page is the chart in NATOPS? Or just title so I can ctrl+F that junt.

WildBillKelsoe Posted March 30, 2019 Posted March 30, 2019 according to the bundled training tutorial mission, you should set a 2 degree nose up trim for cat shots. AWAITING ED NEW DAMAGE MODEL IMPLEMENTATION FOR WW2 BIRDS Fat T is above, thin T is below. Long T is faster, Short T is slower. Open triangle is AWACS, closed triangle is your own sensors. Double dash is friendly, Single dash is enemy. Circle is friendly. Strobe is jammer. Strobe to dash is under 35 km. HDD is 7 times range key. Radar to 160 km, IRST to 10 km. Stay low, but never slow.
Victory205 Posted March 30, 2019 Posted March 30, 2019 Trim is not a massive issue like it is with a separate stabilizer and elevator configuration. 3 degrees TEU will be fine for all takeoffs in all configurations in the sim, because the pilot doesn't have to overcome stick forces to any real level. If you are more than about six or seven degrees TEU, the aircraft will tend to overrate on a cat shot. The compressed nose strut releases its energy at the end of the stroke to help the nose rotate. There is a ballistic moment while the aircraft settles slightly as the pilot rotates to a lift producing AOA. It's normal. Rotate to 10-15 degrees of pitch attitude for all takeoffs depending upon weight and adjust from there. Takeoffs are pretty benign as long as both engines are running. As always, be smooth and feel the aircraft. Don't yank it off of the deck. Fly Pretty, anyone can Fly Safe.
viper2097 Posted March 30, 2019 Posted March 30, 2019 Is it true that you pull the stick half way back about the middle of the catshot? Did that with 0-1 trim and take off "felt" quite good. Keeping a slow climb, accelerate, and trim... Steam user - Youtube I am for quality over quantity in DCS modules
VC Posted March 30, 2019 Posted March 30, 2019 Training video also says something about staying below 500 feet until 7 miles clear of the boat. Doesn't a full AB climb off the shoot kind of fly in the face of that? I usually have the opposite problem, after the initial jolt and pull-up to not end up in the sea, I have to keep the nose down otherwise I'm at 1,000 feet before I've finished clicking the landing gear handle. Without AB. VC =X51= Squadron is recruiting! X51 website: https://x51squadron.com/ Join our Discord: https://discord.gg/d9JtFY4
viper2097 Posted March 30, 2019 Posted March 30, 2019 I would think, that the "stay under 500ft" thing is according to have no problem with aircrafts in the landing pattern. So if the sky is clear, and there is the necessary, than why nit climb with ab? Steam user - Youtube I am for quality over quantity in DCS modules

Without AB. That's standard CASE I departure: Parallel BRC, 500' AGL, 300KIAS. I don't have much of a problem with the burner; I have more problems with the massive increase in lift and the drastic acceleration increase at around 250kts, but that's a different discussion. Still gotta shove the stick forward to keep from going ballistic, anyway.
Wrightie Posted March 30, 2019 Posted March 30, 2019 Was it only a certain model of Tomcat that restricted AB use on Cat shots? I've heard this a lot recently but a cursory look at Youtube and you can find Tomcat cat shots using AB. The opening of Top Gun has one too If i remember rightly.
Nealius Posted March 30, 2019 Author Posted March 30, 2019 B models were restricted. A models were allowed up to zone 5 AB (IIRC).
