About TTI and TTA on F-15C

[Doug]

When an AIM-120 has been launch, we can seen in the bottom left of the HUD this: M xx yy whith xx and yy digital values.

 

What is xx and yy ?

 

Thanks.

i would assume it is the Corodinates of the Missle?

Yes but which coordinates ?

No, it's the timer ... TTI/TTA forlaunched missile, TTA for the next missile if you were to launch it now.

[Doug]

Once TTA=0, it begin a new timer whith new values like: M ?? ??

 

Look at this video (there is a mistake in the label of the video for the 2nd timer (M TTI ???)).

[GGTharos]

Yes I think there is a mistake in the labelling. It should be A counting down to 0, then it should become TTI (M) counting down to 0 ...

[Doug]

So there should have only one value by timer ?

1st: A TTA

2nd: M TTI

 

and not:

1st: M TTA TTI

2nd: M TTI ???

[GGTharos]

It's

 

1st: (A) 1st missile TTA, 2nd Missile TTA

2nd: (M) 1st missile TTI, 2nd missile TTA

[Doug]

I don't think so. Look at my video. In the 1st timer, when TTA=0, the right value is 19.

Next, in the 2nd timer, we can view the same value which continue to counting down (18, 17, 16, ....).

And which 2nd missile, I have launch one missile. It can't be the waiting missile (just before a launch) because the value T xx (in the bottom right of HUD) is different that the right value of the 2nd timer.

 

:/

[GGTharos]

Good point ... all I say is ... I don't get it :/ Must be a bug.

[Doug]

ok ;)
