Etendard Carrier Landing Question

Hello,
Been doing lots of carrier ops lately..and since i've found the Etendard, i fly nothing else.. Great model.. Can't believe it's freeware!
any ways my problem is, landing on the Clem & and even the Nimits, The Etendard comes to a halt so fast, that it always does a wheelie on the nose wheel, then ofcoure the main wheels slams the deck with a sparky display.. no matter what speed and angle of attack i try
it seems the deck wires almost have too much tension for the Dard ,as it stops half way on the deck .and too much deceleration causes the plane to sink to the deck and perform the notorious wheelie .. Actually there's no need for that kind of super stopping abilities of the cable, half the deck is still there!

How can i change the stopping power/tension for the Dards only, without compromising stopping distances/Arresting power for other planes (T-45c and Acc. Hornet stop normally with no need to fix a gaping hole on the deck afterwards :) )
 
Tension

mar,
Well the simple answer is: The more speed on trap=the more 'cable_force' you need.

Etendard:
.......................................
As you can see, they (?) use parameters simular to the F-18 for Etendard.
//Etendard settings: (simular to F-18): This is what makes it hard to mod the cnt pts
(and compression on nose wheel, etc). Changing to '0.0, 0.0, 0.0' for both ref and cofg would require lots of work but that would be the 'definitive' fix.

reference_datum_position= 36.90, 0.00, 1.64
empty_weight_CG_position=-35.79, 0.00, 0.00

//Etendard setting: (might not be exact due to model, but s/b 'close'):
[TailHook]
tailhook_length=3.0 ;(feet)
tailhook_position=-46.9, 0.0, -0.5
cable_force_adjust=1.0

//Suggested mods:
[TailHook]
tailhook_length=1.000 //shorten hook
tailhook_position=-46.900, 0.000, -0.500 //no change
cable_force_adjust=2.000 //increase 'tension' to eliminate 'whiplash'

.......................................
//Or, it MIGHT be like this:
[TailHook]
tailhook_length = 5 ;(feet)
tailhook_position = -17, 0.0, 0.0
cable_force_adjust = 1

//Suggested mods:
[TailHook]
tailhook_length=1.000 //shorten hook //might try '2.000' (max).
tailhook_position=-16.250, 0.000, -0.600
cable_force_adjust=2.000 //increase to tame 'whiplash' //try 6.000 (max).

(Note: BUT the nose wheel compression and your landing SPEED do make a HUGE difference when it comes to the 'whiplash'). (So...keep speed to <120 kts!!!).
....................................
So, there you have it. The whole burrito on tail hook mods. Well, almost, as there IS some trial & error (testing) to do for final settings. But it all boils down to WHAT your SPEED is on touchdown, and that depends on your flying 'SKILL LEVEL'.

Hello,
I'm not sure that settings are involved in your problem.
Before any changes in aircraft.cfg entries (and especially the CG which may have a high impact on flight behavior) I'd suggest you to check your landing flight data.
The main instrument is the BIP : the 3 colors light box (AOA indexer)
You can't trap properlly without taking it into account : yellow when trapping => crash for sure!!

Please read the documentation it was written by a former Etendard pilot and instructor so you can trust it.
Regards,
Sylvain
 
sparouty, I was looking at those proposed change of

reference_datum_position= 36.90, 0.00, 1.64
empty_weight_CG_position=-35.79, 0.00, 0.00

Reference datum there I think would be in front of the aircraft and the empty weight would be behind.

Personaly I would recommend people who have no problems with the aircraft leave the aircraft.cfg alone, the tailhook settings are in the model and work ok.
 
Model?

Well, he did not tell us (me?) what model he was talking about, so my input IS pure conjecture (or, 'educated guess'?). Just because the hook 'works' doesn't mean it is correct, or that it can't be adjusted. It would require trial & error, but I don't know which model it is.

The F-18 needed cnt pts adjusted, due to nose wheel digging into deck after trap. It wasn't all hook adjust, in other words. They do work together. But no one wants to 'rock the boat', so they don't talk about it. And so they go get a Coral model, or some payware, and it's the SAME THING. Ha. Too bad, so sad. I asked one guy who runs a VA (Navy, with lots of carrier landings) to make a video as he contended the F-18's nose wheel did not dig into deck. He didn't make a video, and he never returned my emails. Ha.

I suspect this one I do not make educated guesses either this will probably get me banned. But if you do not know find out !!

I am sick of seeing Being helpfull is more important than being right, how can you be helpfull if your info is wrong it helps no one.

So its bye from me and bye from him as the 2 Ronnies used to say

Etendard IVM

I would request the originator of this thread to request it be locked there is no more to be gained by keeping it going.
 
No need to ask the thread originator about closing the thread, I'll do it because it needs it.

Our motto: "Being helpfull is more important than being right" is clearly about attitude, not fact.
