View Full Version : ATC queries

For our ATC friends - looking to answer some queries based on a flight from Mt Gambier to Adelaide last week.

1. (This is a briefing issue) - the database which holds the waypoints used for wind/temprature profiles has ALEXI at the wrong location - according to NAIPS it's a bearing of 188 and 148 NM from RUVUS when it should be bearing 318 and 40NM. Does someone care about this? Who would I point the error out to?

2. I was issued the ATPIP2 STAR into Adelaide. My poor old 601P can't go as fast as the required speeds in the STAR - I queried this and was told it was ok and just to use profile speed. This seems odd that a STAR requires a certain performance but if I can't meet it then not to worry?

3. Profile speed - I don't know what my 'profile speed' is (profile speed usually depends upon how poorly I've managed the descent!)? How do ATC? Can I find out what is expected - the ICAO type is AEST and across the various variants - 600, 601, 601P, 700 (and all the subvariants) there is massively different performances - cruise speed anything between 170 and 240kts for example?

Thanks in advance

1. Someone here might be interested Pilot Briefing, NAIPS and NOTAM services | Airservices (http://www.airservicesaustralia.com/contact-us/ausfic-pilot-briefing-naips/)

2. See AIP ENR 1.5 - 46. These speeds are "Standard terminal area arrival speeds" and only apply in certain circumstances

3. "Profile" speed is just your normal un-atc-molested speed. We don't know exactly what speed you'll do, but that goes for everything including jets. Do what you'd normally do and we'll ask or tell you if we need something special. Of course there's always the chance we'll stuff it completely and then Approach will reward you (or the guy behind you) with a vectored scenic tour of South Australia :)

STAR arrival speeds are there so that the traffic has a predictable deceleration on to the approach. It only applies to jet and turboprops category B, C, and D. If you are slower than the STAR speeds anyway then you go your normal speed until the STAR speeds become limiting. Your Piper Aerostar is exempt because it is piston engined.
