Dynamic Spawn with Invisible/PAD Single FARP has very wide space requirements.

[SabreDancer]

As exists in-game, dynamic spawns with the Invisible and PAD Single FARPs require a clear area of over 100 feet between positions to spawn helicopters. If this is not followed, both FARPs will become unusable and result in messages stating "pending free parking space" and, if a helicopter is selected, "all spawns/parking slots are currently occupied. Please try again later once a parking spot is free".

As shown in the attached image, the individual spawns would be tight but doable in the Mi-8, and quite open in smaller helicopters like the Sa-342.

Additionally, adding an object underneath to spawn on, like for example M92 Sandbag 11 (the sandbag helipad), results in the same message with one invisible FARP placed upon it. Helicopters are able to spawn on this object with a traditional spawn slot.

Im doing a bunch of test with this same issue.

I have found how to make it work!!!!! so start out by placing your invisible FARP as you would have always done. 

Next set up your Dynamic slots for the FARP as you see fit. If your going to use Dynamic slot templates make sure you set them up at this stage before moving on to the next!

Using the unit ""number" of "number" increase the number of units to the number of slots you want for that FARP. They are going to show up in a line like so. 

once you have the number of spots you want to can move them around in the location you want you FARP to be at. 

Once you have them set up like you want them there is one thing you need to check. Make sure that the group name for each spot matches the group name for the FIRST spot, in this case its Static Invisible FARP-1. check that your spots match that and that the unit name increases incrementally with each spot for example the 3rd spot (highlighted yellow) is "Static Invisible FARP-1-3" as its the 3rd unit. 

 

ANNNNND that should do it.

That's a pretty handy technique! Thanks for sharing.

I know this is a slightly old thread.   However, figured I would post my fix.  I was setting up a FARP with dynamic slots.   When I placed the invisble FARP and then placed the vehicles for re-arm/re-fuel etc.   I was getting the same error.   After trying a few things, I realized that I may have put the invisible FARP too close to the vehicles and some other units placed there for candy.  Moving the FARP from 15ft away to 50ft away from the closest object fixed my problem.   I didn't have to jump through all of the hoops mentioned above.  Might work for some!

I had a similar experience as ZeroDay. I must have crowded my regular FARP with support statics too close to the 4 pads on the FARP. Once I moved the statics a little further away (still on the FARP), the problem went away.
