Re: R/T status in KL FIR
7 - 8 nm spacing
Our current procedures require the following:
a) radar separation of 5 nm or wake turbulence separation whichever is greater; and
b) when the first aircraft crosses the threshold, the succeeding aircraft must be at least 5 nm from the threshold.
There are others in place when visibility goes below a certain value and so on but the above two are most significant.
When KLIA is operating on a segregated mode, most controllers aim for a 6-7 nm spacing on finals to achieve the requirements of para (b). Some do actually try and actually achieve a tighter spacing when wake turbulence is not an issue.
With traffic levels going up, it is only a matter of time that the spacing requirements will be reviewed.
