My thoughts on this whole speed stuff!
1. On reaching TOC ATC are informed if your TAS will be say+/- 10kts from FPL. We can then amend the FDR in the blink of an eye and all sectors down the line will have the info. So will MAESTRO.
2. With respect to descent speeds and the current situation i.e. Raffertys Rules. If you are not asked what your speed will be on descent prior to TOD then when assigned descent clearance read back the assigned level and your planned descent speed.
Simple stuff really. Maybe i`ll start the paperwork tomorrow. We should have something in AIP by 2007.
