No National Guard UH-72A Lakota,12-72228 with FLIR and Camera.
Aha, it didn’t show the helicopter icon (I saw one of those too on my screen). It has very low speed at times (as low as 39mph in “turns”) so I was curious…
This is what I was expecting to see (Bell 407).
To choose an icon, dump1090/skyview either needs to know an aircraft type (by looking up the 24-bit aircraft address in a static database) or see an ADS-B identification-and-category message (only available from ADS-B equipped aircraft, obviously, and even then the category is often not set). If it doesn’t have either of those available you’ll get the default icon.
