I was reading the NOTAM yesterday on the A1 UK Notams which does say that due to poor height keeping, the EMB 135/145 and the 146/RJ family are not approved to fly above FL290 and operators should plan accordingly.(A1871/01). How come BAeSystems haven't done anything about it especially when RVSM has long been planned and most of the 146/RJ's are in the UK.What are (ex)Flyer and British European going to do now? It's not exactly the best time to start increasing fuel burn? Or am I talking totally out of tune-do most of these flights ever operate above 290?
