IVAO vs VATSIM: controller habits

<< < (3/3)

EHM-1883 Matt:
ah! Thanks Conrad;D

EHM-0654 Murray:
To expand on Conrad's explanation just a little, a STAR is basically made up of two points: the IAF (Initial Approach Fix), and the FAF (Final Approach Fix), plus the routing to get between the two. After the FAF, if you're under ATC control, you may well be vectored onto the ILS, otherwise use one of the landing plates to get onto the runway.

A big problem with charts is that both the STAR and the "landing" charts are called approach charts, which if we are honest is a little confusing.

EHM-1358 Tim:
I remember LGAV having STARs that went all the way to the ILS.

EHM-0654 Murray:
Tim, it happens, the FAF on the GANSU STAR to RWY 03 at LPPT  puts you on the ILS at the OM at 2700', if you're using AUTOLAND you should be in APP mode crossing the FAF with VOR LOC established...

While some airports have wiggly approaches from the FAF, that are ATC "driven" (EGLL, LHBP), which give the controllers a chance to coordinate disparate traffic streams into a single whole to land on one or two runways, other airports put the wiggles into the STARs and associated stacks, and even operate multiple runways for approaches (EHAM is good for that). On IVAO traffic levels are such that it is rarely necessary to operate real-world STAR procs, but it's just one of the many reasons I really love the IVAO-GB EGLL real-world events...

EHM-0001 Gergely:
Q1. A STAR is to regulate arrivals when there are lots of planes in the TMA (5 or more arriving at the same time). So if there's only a few planes arriving, there's no need to use the STARs in order to minimize delays (flying a STAR can add 5-15 minutes to the flight time, and you use more fuel). So it's a courtesy on behalf of the ATC, to get you down earlier. However, if you still want to fly the STAR, just tell the ATC (request to proceed with ... arrival) and I'm sure you'll be recleared for it.

Q+1. Just ask the ATC for holding instructions and he'll tell you (e.g. inbound track 150, right hand, 1 min legs)

Q2. This is a 'shortcut', you skip a portion of your route and fly a shorter route, e.g. your route was A-B-C-D-E and ATC clears you from B to E, so you'll arrive earlier and use less fuel. However if you can't (or don't want to) comply, you can tell him 'request to proceed via flight plan route' and he'll leave you to fly the planned legs.
