Instrument Procedures - Departure
hello all
well im a studient pilot at the moment , i have came to a chapter in Airlaw ATPL book , that i really dont understand which is (Instrument Procedures - Departure ) i just dont get it , what is SID points (standard instrument departure) and i have looked over the internet , it got something to do with the Flight managment computer FMC , thx , hope i get an answer :) |
its just points on a departure which we have to fly through while flying from an airport.
You don't need any fancy kit to do it with they can all be radio aids and intersections or distances. |
SIDs (and STARs) are mainly used at bigger airports. If a normal departure is to go direct to "A" then "B" then "C", crossing "C" at 3000 feet and then going direct to "D" and crossing "D" at 5000 feet and departure control will be on 123.75, ATC can publish all that and call it the Apple1 departure. Then all they have to say is, "You are cleared the Apple1."

so its more like a way point , when at point a you increase altitude , point b you turn heading ..., correct me if im wrong , and nowdays they use VOR station to do that , so first VOR is A second VOR is B
and what is the abbreviation for STARs Thx for the answers guy really helpfull |
Adding to previous answers, at some larger airport the SIDs may incorporate noise abatement procedures. This may mean that the route is not the most direct after take-off.

thx again
i now get it , ---- MarkerInbound So SID is for Departure and STARs is for approach , correct me if im wrong , ------- guys i have another question since you guys are talking about noise abatement i was living in london just about 5miles from Heathrow Airport , and as you guys know Heathrow Airport is one of the most busiest airport in the world , how come i didn't hear any aircraft noises o.O |
Yes, the STAR is an arrival and the SID a departure.
Yes, they're just waypoints. While traditional SIDs and STARs are based on VORs, newer procedures are based on Random Navigation (RNAV). With most large aircraft, probably most aircraft in general, having GPS or INS, the people who design the routings are no longer limited to VOR/NDB nav waypoints. The FMC knows where it is and it knows where points A, B, C and D are so it tells the pilot or autopilot what direction to fly. |
RNAV = Random ... :D nice Freudian slip
