Parallel Runways

Sat Oct 07, 2000 11:43 pm

Does anyone do the minimum distance between 2 parallel runways so that they can be used at the same time?

750m Max

Hello,

I know that parallels runways are at maximum 750m far one from the other to be considered as parallels.

Best regards,
Alain Mengus

In order to operate simultaneous operations (two aircraft landing at the same time), you need 4300 feet inbetween the centerlines of your parrellel runways.

The 4300-ft rule (US only?) refers to simultaneous independent instrument landings. If ATC keeps the aircraft staggered (i.e. not alongside each other) ILS approaches can be flown to closer parallel runways, and of course in clear weather airliners land side-by-side on SFO's runways 28L/R, which are 750 ft center to center. The legal minimum is maybe 700 ft (?).

At SNA the runways are quite close together between each hold short bar there is barely enough room for a 757. So I would guess it is about 200 feet. With 19L being 75 feet and 19R 150 feet, that makes them very close together.

SNA

If we can believe the lats and lons on www.airnav.com then SNA's two runways are 500 to 501 ft apart, center to center.

What about FRA? as far as I know they cannot use their runways simultaneously for landings. Hopw far are they apart?

We land on both of them all the time but they can not do dual ILS approaches, which requires more room.
