I think 'Land After' is a cop-out at precision IFR ATM airports such as Heathrow. It's lacklustre and brought about by the high pressure on runway utilisation. Because of the confusion highlighted above I think that 'Land After' should be consigned to the nats Room 101 bin of doubtful, non-robust procedures (such as 2.5 nm spacing). If the airport cannot operate using standard robust procedures then take some of the runway utilisation pressure off in the interest of the flight safety of the fare-paying passenger. It took a whole raft of go-around incidents at Heathrow before robust (non-intervention) go-around procedures were introduced. Every approach is to a potential go-around, so there should never have been any need for reactive intervention. I think 'Land After' at major international airports such as Heathrow shoddy buck-passing. If there is insufficient spare capacity for a robust landing clearance, then airport operators should create some by relieving the pressure.
