AFI Standards
Hi Chris - not much has changed except "authorities" insisting on the implementation of RVSM in this deficient region. ICAO guidelines are published for this, however, not too many of these are ever met! Efficient/reliable two-way comms being just one of them - how often are carriers unable to raise Kinshasa on HF for a few hours and this region lies within the ITCZ! Turbulence will/is going to cause unnecessary RA/TA's with no one aware that should suspend RVSM until it subsides. Just what percentage of over-flight charges are ever put back into the necessary resources???
