A-4E-C LABS vs COMPT?

[FalcoGer]

The weapon mode selector knob has 2 positions for computer assisted bombing. LABS and Computer. What's the difference between the two? The A-4E Community guide doesn't include the computer position.

What's the difference between the two?

When do you use each one?
How do you use each one?

Is there a more updated and more in depth manual for the A4? I have HECLAK's guide, last updated 4th June 2019

Computer is the one you should use since last couple of versions. It is a sort of CCRP system, and it is quite accurate for its time and purpose, at least in DCS. In older versions of the mod, since CMPTR position of the dial wasn't yet animated, this functionality was accessed through the LABS position of the dial.

 

LABS isn't modeled in A-4 right now, but if you wonder it and have F-86 you can test it there. Basically, it was made for "over-the-shoulder" delivery of tactical nuclear bombs. You pull straight up right over the target area, depress the bomb release button, a gauge shows you your deviation in x and y axes since you've depressed the button, and once you reach a certain angle the system decides that the bombs will fall where you've pressed the bomb release and pulled up, and releases them. In practie, you're lucky if they even fall in the same postcode you intented  It really was meant more for using with tactical nukes.

 

A-4 being newer, LABS system may have seen some improvement in the meantime, don't know, but don't think it'll be night and day better.

 

So even if LABS was implemented, for great majority of stuff we tend to do in DCS, computer is the one to choose: CAS or strike missions with conventional bombs. It is a lot easier to use, and a lot more accurate.

Looks like for CP-741 function the Func Sel Sw should be CMPTR.

 

LABS is for nuclear weapons delivery with various options including the famous dramatic looping flight path.
