Ever since the pfm upgrade I've found myself using TWS less frequently. In scan mode all visible targets are displayed on the HDD with their speed(not in numbers) and relative altitude. Besides the fact that TWS goes dead in the presence of jamming, placing the box over a contact does not show the speed and altitude anymore. Which makes me wonder, what is the point of having TWS mode? Is is it still useful for anything? Is there something about is which is not modeled yet?
