Well well well... So JIA gets a rapid exit taxiway.
The poor ATC's there have got used to being blamed for everything related to delays. Whenever someone hits the heidelberg hold, atc dla. The fact that the radar systems are being upgraded to the tune of approx 230mil ZAR, it's only fair that now acsa started spending a little of its gigantic profits on the airport infrastructure.
Prior to this, only when landing on 03R and vacating on taxiway E, it led to a somewhat high taxi speed, as it isn't a perpendicular exit. At joburg the traffic is spaced 7 or 8 nm on final for the same runway where a heavy is in front, whereas the rest of the world is between 3.5 and 5nm only due to rapid-exit taxiways. You do the maths and see how many more aicraft can land per hour...
URC
