That makes more sence. The heading from the IP can be close to the FAH, if the attack geometry is what the JTAC wants, but does not need to be. Usually in the remarks section of the 9-line the FAC/JTAC issues any FAH restrictions.
I would recomend maybe making a note of that in the mission briefing though as line 2 (heading) and FAH are usually briefed seperatly.
*shifting gears*
The missions of the campaign I have played are awesome. It is really cool to be put in a stack at a holding attitude and hear the other strikers getting pulled out to do the work. Some things you might consider when building future missions (of which I am sure to buy) is putting any bombers and UAS at the top of the stack as they don’t usually go low. Also to increase the level of ‘real,’ pull from the bottom of the stack and step down the holding sections, or, if pulled from the middle of the stack, issue specific egress instructions with altitude assignments to de-conflict with other A/C when routing back into the holding stack.
Either way, I am thankful for content creaters such as yourself! Thank you for making campaigns for DCS! More harrier please!!!
