SID/STAR discussion for everyone but Razza

(1/2) > >>

EHM-0654 Murray:
Jon Rasmussen sent me a PM this afternoon asking for a basic explanation of what SID/STARs are and how they work.

That got me thinking, so in hopes of a "sticky" topic in the future, and for the benefit of everyone else, here's what I came up with after answering Jon's queries...

You can think of SID and STAR charts a bit like AutoRoute maps that work in three dimensions - they tell you (the pilot) how to get from point A to point B along proscribed "roads", and they throw some altitude minima/maxima into the mix (STAR charts will often add a speed limit as well), in order that you stay safely away from other traffic.

For a SID, point A will be the departure runway (at runway alt) and point B will be a navigation point of some description (usually a VOR, but not always) where you can join the en route airways (at or climbing to your cruise alt).

For a STAR, points A and B will both be navigation points of some description. Point A will be some distance away from your target airfield (sometimes at your cruise alt), and point B will be closer to your target airfield (and closer to the ILS intercept alt).

(there will be more...)

EHM-1500 Jim:
Yep...SIDs and STARs are as Murray says...basically pre-programmed departure and arrival routes to an airfield...allows ATC to ensure that all inbound and outbound traffic is on a specific route and at a specific altitude so they stay out of each others way and ATC doesn't have to keep telling them where togo - i like to think of them as the slip roads on and off motorways at the beginning and end of your journey - SIDS tend to be specific for each runway and can be affected by your desti9nation heading...STARS are not runway specific, just get you close to the airfield from where you will receive vectors to intercept ILS....

www.ais.org.uk

Registration is required but is free. This gives you access to all UK charts including SIDS and STARS. Great resource and really worth getting in to.

Best of all it also links out to similar resources for other countries so you can pull down data on SIDS STARS for pretty much anywhere - it is certainly easy to use for most of continental europe.

i found www.ais.org.uk very very useful for getting SID/STARS its very simple to use aswell a really good site thanx
