Keep your ear to the ground regarding the introduction of the new FDR's. These are being phased in on old aircraft after 2005, and on new builds from 2003. To meet NTSB recommendations A99-16 to 18. Get some money into Spirent Systems (used to be called Penny & Giles) if you want to see it grow. Their new MPFR is a nifty bit of kit and 35% smaller than the old ones we have at the moment.
