Need some basic help with the airspeed indicator

[sirrah]

I thnk I have been spoiled with all the digital HUD indicators on all modern aircraft I've flown in DCS, because I'm struggling with some basics in the F-14.

 

On page 48 and 49 of the HB manual it states:

 

3. Indicated airspeed scale (inner) - Readout for indicated airspeed from 200 knots to 850 knots. Covered by airspeed dial until relevant.

 

I don't understand how to read this on the airspeed mach indicator.

 

E.g.; Can somebody point out to me how I can see I'm doing 350kts at landing before the overhead break?

What you dont see here is that as you get faster the mach part of the gauge moves around clockwise so that mach 1 will be where the orange 5 is on the picture above.

 

As you accelerate and the mach numbers move clockwise you will see 200knts, 300kts, 400kts etc all start to show up where the orange 3 position is in the picture above.

 

The needle (orange 1 in picture above) will show what your airspeed is and mach number as you accelerate.

 

So for example at approx 23,000ft doing 400 knts (pictured below) you'll see that the needle shows you doing 400 but will also be pointing to mach 0.90. This means at that altitude doing 400kts will give you mach 0.90 however this will change with altitude, so at 40,000ft you could be doing 300 kts at mach 0.90 (not accurate just an example) and the gauge would show 300knts and mach 0.90 instead of 400kts and mach 0.90.

The indicator has two scales, one outer from 0 to 200/250 kts then switching to Mach scale. The second inner, continues from 200/250 kts to 850 kts and is shown in the gap, between the needles. Try to remember typical clock position on approach. 7 o'clock equals about 350 kts, etc.

Mach scale is important when at altitude as it compensates for pressure altitude and is more relevant when in combat.

Thank you both! That explains it.

 

Next step is to be able to actually read the gauge in VR, but that's more of a hardware issue on my side ;)

I'm struggling to read it too.. And even not in VR! ????
