JTAC 9-line
-
Yeah it is a bit confusing to me. The disconnect seems to be that a point on the Bravo 090 radial (B6 or B25) is called the IP (Line 1) when in fact the heading for the run-in on target is not 270.
The operational IP would be somewhere on radials between A and B - and closer to B than A - from which one can assume a heading of 247. But maybe the idea is that the “IP” stated is the best approximate cardinal direction best suited to line up properly on 247. If so, flying through B6 gives very little room to manouver onto 247. B12 or B15 would make the run-in more doable.
I tried to sketch how I view it, it might be off but at least it is easier to talk about visuals that way:

To dissipate any doubt, Echo is not target location. It’s probably not too far from it, but it can be as far as B6 is from Echo in BMS standards (6 nm).
-
@LorikEolmin Right, I was referring to the Line 6 coordinates as the Echo point. They may be different.
-
I’m understanding now, the only thing that is not clear to me is the Offset. I don’t know at what point it should be done.
-
@Leandro over the IP - check out that diagram I snipped from the training manual in my prev post
-
so is this?
-
@Leandro disregarding the training manual - go with what the JTAC says - the IP is B6, start a quick offset and then turn quickly back to FAH 247 in time to release. I need to reread up on the gbu54 and it’s minimum release range/ symbology …
-
@AWmk1 okay, I’ll do that

Re: JTAC 9-line
Was watching this video slightly confused myself on orientation and direction.
So clue is follow JTACS instructions.
Is it tied into way-points
This whole offset aim-point and offset direction thing throws me off.
-
@Reaperdog1 lol this is my video, ahhh … sorry reaper.
-
@AWmk1 Aah, sorry to quote video it is good though high lights points to discuss and get things right.
Probably a case of RTFM but these type of videos help define how to do it following steps.
So where are we at?

Some official info from the Army/ Air Force

:
h) JTACsdetermineIP/BPandegressplantosupportattackgeometry(lines 1,2,3,9). JTACs should strive to use control points for ingress and egress that do not make it necessary for aircraft to make inordinately large turns in order to abide by FAHs.a) Final Attack Heading (FAH). See Chapter III, “Planning and Requesting,” paragraph 14c(3)(d), “Final Attack Headings,” for more information on FAHs. When using cardinal directions for the attack heading, aircraft FAH should be +/- 45-degrees of the cardinal/sub-cardinal direction (i.e., if north to south, then aircraft FAH should be 180 +/- 45, or 135-225).
As a technique ,FAHs should not be planned over friendly positions (i.e., occupied HAs, BPs, OPs). However, on linear battlefields where aircraft traditionally hold behind friendly positions, JTAC/FAC(A)s should be aware that attacking aircraft must often overfly friendly positions en route to the target area
JTACs/FAC(A)smustbeawareoftheeffectsofshortorlonghitsalong the bomb-fall line or weapon-to-target line. In general, FAHs should be planned to be as close to parallel to the FLOT as possible.
————-
On LINE 2:Line 2―Heading and Offset. The heading is given in degrees magnetic from the IP to the target or from the center of the BP to the target. JTACs/FAC(A)s give an offset (offset left/right) if a restriction exists. The offset is the side of the IP-to-target line on which aircrews can maneuver for the attack. Give 3 digits sequentially “One eight zero.”
—————
Something missing from bms’ JTAC is him providing us a holding point, such as Bravo 25,or “orbit overhead echo point” or something:a) Aircraft Routing/Holding Instructions. Upon initial contact, each controller shall at least give “maintain” instructions in order to establish control of aircraft (see Figure V-3 for an example of routing calls).
Example Routing Calls
“Proceed xxxx and report established”
Call for aircrew to proceed to a location/elevation and verbally report when established
Directive call for aircrew to hold at the specified location/altitudes
Call for aircrew to verbally report passing the specified altitude
“Maintain xxxx” “Report passing xxxx” -

@AWmk1 Damn had to ask lol now got homework, I’ll give it a good run through when got time ~ thanks though
-
@AWmk1 @Leandro @Reaperdog1 In addition, here are the updated pictures for U1.
Hopefully its clear now :
If not let me know.
-
@Micro_440th is there a way to have the JTAC assign the CAS pilot to orbit somewhere? Or is that implied as out past bravo 25?
-
@AWmk1 No, the BMS JTAC is not able for now to assign flights to their holding point (as mentioned in the training manual)
-
@Micro_440th I don’t expect the U1 to arrive, it look greats
