Speed is just as important as heading and level requirements because if you get the speed right you can avoid heading and level restrictions. I totally disagree with PERA about not saying anything. I never coordinate to the next agency about speeds because we get too busy but what i say to the pilot is "CONTACT.....ON.....REPORT SPEED ON FIRST CONTACT" If I was a pilot I would always tell every controller what my speed was when decending into an airfield you know the sky is littered with like minded pilots wanting to get on the ground. Good airmanship at the console or in the cockpit is invaluable but obviously too much info can be a problem. Different acft speeds is what causes most conflictions so it makes sense to call it. If we all flew the same type at the same speed everytime we all know what the outcome would be.
Most readouts controllers get on screen is the ground speed which is calculated mathematically by the system from the raw radar feed. So ground speed and IAS can be substantially different and there is nothing worse than asking a pilot with a whopping ground speed, closing in on another guy, to reduce to 280/290kts and he is doing 270kts. Constant speeds for the pilot are appreciated and save fuel which is high on any airline agenda and if I had my way, speed would be a mandatory piece of info in an arrival call prior to decent.
