DLINK Behaviour at start up?

Thanks for responding. That is what I have been doing and having success for Instant action missions. Seems this campaign mission behaves differently for unknown reason.

Is this a cold start instant action? For any hot starts, the jet should spawn fully aligned, MIDS on and with DL working. 

Campaign could be using an out of date .miz. But iirc power cycling the MIDS switch has always been a surefire way to correct any problems as long as the alignment was done correctly. Try a stored alignment and wait until it is flashing on the HUD, switch to nav quickly (don't linger on the normal alignment position, double click through it) and turn MIDS on afterwards. 

If it's an old .miz you might see GPS time set to Off in the LST ENT DED page. If you want, turn it on, or don't.

The LST ENT DED page does indeed 'turn on' with GPS time set to On, whereas before it would be Off. Same was true for hot starts and was a recent update.

Is there a specific issue you're encountering during startup? Idk if this is the correct behavior, but I haven't noticed any in my starts. GPS time shows correctly when verified against the f10 map clock. 

I'm not 100% sure GPS time does anything currently, but I could be wrong. 

there is no problem, its the change that is in question , my understanding is that GPS time should be set to off in a cold start, and the fix should only have impacted hot/air starts 

GPS time is required for DL to work correctly

That's my understanding as well. 

I've always turned mine on, but the few times I've forgotten with a hot start, DL updates appeared to sync just fine. I haven't seen it confirmed whether it's actually doing something in DCS and the clock shows the correct time when it started in Off from cold.

I suppose it's a moot point now.

Thanks for trying to help. I've tried everything recommended with no success so far.

While I thought this was a general F16 issue, it seems to only occur in one or more specific campaign missions. I've joined a thread in that forum with other people observing the same or similar issue.

It is a cold start, on taxiway, in Syria.
