No on the 'new' system, the destination airfield is not notified. UKBF only notify their local office and local Special Branch.
Depending on your destination, you should book PPR separately, but most airfields accept a copy of the GAR or the new GAR receipt as a PPR request. The airfield where I work has a system whereby if you e-mail it to us, it automatically gets forwarded to BF and SB, thus you can e-mail it after the airfield closes and still give the necessary 12 hours notice where it is required.
