Dragon1-1

Viper has a different datalink system, and can't receive 9-lines in text form. It's a feature of SADL, which our Viper doesn't have (IRL there exists a different block that does).

"Nails" is the word for an RWR indication. "Contact" is the one for radar.

Ships in DCS are simplified, and they have way too much hitpoints. AGM-88 would do nothing. IRL, it's not a good way of dealing with a ship's radar, either. It could damage one of the antennas (ships typically have a lot of them), but it won't do much otherwise.

It doesn't. AIM-7M is new enough that the delay had been practically eliminated. It's got digital electronics and a new seeker, which went a long way towards making it not suck.

This is not possible IRL, either. Shrike is essentially a Sparrow with the seeker retuned to seek a specific kind of radar. Later variants had some flexibility, but it was for most part hardwired. Even if it could track Patriot radar emissions (I'm not sure if it can), a corresponding head was never designed, because why would it be? Even if we're considering Iran, Shrike was long out of service by the time Patriot came around, and it doesn't really have the kinematic performance to hit it from outside its range.

It is working correctly, from what I gather, this is just a display bug. FYI, the BA you set on the MFD does not actually affect the bomb, the setting is a physical switch on the casing that has to be set on the ground (something we can't do in DCS yet), and you later set it on the MFD to match, so that the jet provides you a proper solution cue. Since you can't have it at anything other than 1500ft, the setting on the MFD doesn't actually matter AFAIK.
New fuzing will introduce both a way to change the actual BA, and necessitate the proper data entry for it to work.

You won't see damage after a single flight. You will see damage after doing it on every flight, day after day, for some time, and then landing the thing on the boat. Your crew chief will likely see it first and be ticked off at what you're doing to his jet. The squadron CO wouldn't be happy about having to write a jet off early. That's the sort of thing we're talking about here. 
A plane in Red Bull Air Race has to hold together for the duration of the race. That's it. A Viper doesn't deal with salt water, carrier traps, carrier launches and all the general beating up that Navy birds have to endure. I don't know what was the official policy on the "Top Gun switch" in the USN back when the old Hornet served, but it had to do with preserving the jet's operational life. 

They mostly flew Yaks, Pe-2s and (most famously) Po-2s, though. I'm not sure about the La-7, but the I-16 was mostly an early war thing and unlikely to have been assigned to female pilots. By the time they were having women fly, there was plenty of Yak-1s. Also, Lavochkins were the best the Soviets had at the time, and as it happens, the good stuff was rarely assigned to female regiments. As such, it's probably not historically accurate for either airframe.
It'd actually be really nice to have the Yak-1, seeing as it was a docile, well-behaved aircraft that was nonetheless still able to run circles around the German fighters of the time. Armament wasn't terribly heavy, but it was powerful enough, and being mounted on the centerline, rather easy to aim. We don't have an appropriate map anyway, but any of the Yak's incarnations would be a joy to fly.

That's because you have NVGs on, not HMS. I think the defaults might have gotten swapped around.

In the A-10, you shouldn't be seeing any of them during the day. The director lights were designed for the likes of B-52, with the receptacle way behind the cockpit. Both are visible in the F-16, for example, although by no means easy to see. The A-10 has its slipway in the nose, your reference is the boom itself (it gets illuminated by your AAR light at night), not the lights. 

It's a legacy mode meant for strictly preplanned strikes. It was originally designed for use with nuclear weapons, but it should work well enough to also loft CBUs. For regular bombs, it's not the best because of low accuracy. 
Basically, the use case is when you want to follow the exact loft parameters you planned. Otherwise, it's inferior to CCRP (DTOS is a visual designation mode, LADD works off the SPI).

How about an answer that doesn't take 12 minutes to watch? Dunno why would it be marked as solution, I wasn't able to find the answer skipping through the video.
For the record, the reason is that the Viper's FLCS in roll is actually pretty dumb. AFAIK, it was decided not to overcomplicate things when the Viper was being developed, the designers had no idea if the relaxed stability concept will pan out, and as such, made it as simple as possible. The pitch component was a really big deal, due to relaxed stability, but roll wasn't unstable, so they didn't bother implementing a system to keep it in check.
Here, and it took much less than 12 minutes. Reading>videos.

For the first part, it's probably rounding error. DCS is made by an European company, so internal values are metric. One kg is about 2 pounds, so you can expect errors of that magnitude when things start to add up. Basically, what the system shows you as "4lbs" may internally be something like 1.67kg, which, when multiplied by two, will give you 3.34kg, which would be shown as 7lbs. So you appear to lose a pound somewhere, and depending on the rounding method used, those errors may accumulate.
Second part looks like a genuine bug.
