I once posted this in a PM for us Hollo Pointe flyers to pass data to Hornets for LGB deployment. With the JDAM out, it’s time to share and update it! This should help with those wishing to do recon & Strike with mixed airframes, or even CA.
A quick lesson for coordinate adjustment in flight for laser guided bomb deployment with a target point in the Hornet.
Since we cannot yet use MGRS coordinates in the Hornet, Long/Lat worked well but requires some conversion.
There are two common ways to show long/lat in DCS and I will show the same location here:
Direction, Degree, Arc Minute, Arc Second
Direction, Degree, Arc Minute, Decimal
Note: Rounded to two places - additional digits from TGP’s not needed for the Hornet…yet.
The conversion here is easy - 30 seconds is half a minute (50%).
|Hornet UFC (Entry)||Arc Second|
|Hornet HSI Display||Decimal|
|Hornet JDAM Planner||Arc Second|
So take a TGP decimal readout of say 87, and multiply that by 60:
0.87 * 60 = 52.2 (we’ll call it 52)
And reversed by the hornet’s flight computer:
52/60 = 0.8666666.
Now I haven’t definitively tested it, but the Hornet may round to 87 or truncate at 86. Worst case it’s off by 1% which is acceptable a laser guided bomb to still find the laser. For JDAMs, I’ll have to experiment.
