I had RC for a very short while but kicked it into touch

when Dave M bought out PFE.
The voices are REAL,(radio distortion as an added extra) you have Oceanic procedures,contact Shanwick or Gander Oceanic,Taxi Guidance from Gate to runway and to Terminal or Gate at your arrival airport.
You can alter the altitude in flightplanning to suit your flight to follow proper flight levels...East to West etc.
SID's and STAR's can be added using proper procedures or you can use PFE's SID's or STAR's as an option.
PFE and FDC can be used together which adds to the realism.
And finally....if you have a problem and you can't find what you are looking for , you can
usually get answer within 24hrs and sometimes within an hour depending who's online..
