Basically the title.
IRIS-T triggers both the track warning of the F-16 RWR as well as the missile warning launch, which makes zero sense. It's an AESA radar, assuming it's a Giraffe 4a, so I'd expect it to be able to provide datalink guidance for the IRIS-T missile while in TWS-like mode. Especially when the missile drops the nose cone cap and switches to IR guidance, even then the RWR missile warning stays on.
