parallel approach

[wingtip777]

hello all!
what are the difference between: independent parallel approach; dependent parallel approach: segregated parallel approach.
thanks!

Hmm, only guesssing.. Independent could be where no separation is provided whilst the aircraft are established on the respective ILS approaches. Segregated parallel approach - could be 1) where there is no official separation (like at Heathrow) so radar, or visual, separation has to be provided between a/c on each runway. Dependent PA... no, try me on something easier!

Simultaneous operations on parallel or near-parallel instrument runways

1- Independent parallel approaches: approaches which are made to parallel runways where radar separation minima between aircraft using adjacent ILS ARE NOT prescribed

2- Dependent parallel approaches: approaches which are made to parallel runways where radar separation minima between aircraft using adjacent ILS ARE prescribed

3- Simultaneous instrument departures: simultaneous departures for aircraft departing in the same direction from parallel runways. (simultameous dependent parallel departure mode of operation is not use due to wake turbulence considerations)

4- Segregated parallel approaches/departures: one runway is use for approaches, one runway is use for departures.

5- Semi-mixed and mixed operations: one runway is used exclusively for departures, while the other runway accepts a mixture of approaches and departures; or one for approaches only and the other for approaches and departures,or simultaneous parallel approaches with departures interspersed on both runways........

and the room goes quiet ;) . right, on to the next thread.

He's very good, isn't he?

I like how we got more than we paid for.

Me, I'm stunned. WTG, Gryphon!

THANK YOU ,Gryphon!
YOU SAID SEGREGATED APP\DEPARTURE. BUT AT SINGAPORE CHANGQI AIRPORT, THEY ONLY SAY SEGREGATED APPROACH BUT NOT APP\DEP. IS THAT ANY DEFFERENCE?
