wain71 Posted June 9, 2022 Share Posted June 9, 2022 I am currently doing one of my help/checklist things for the Fenix, I do them for most airliners etc.....anyway I was reading about the IAF and Greendot speed, now I understand the term and what it means along with Greendot speed, my issue is where do I find this info? Is it somewhere in my Simbrief flightplan? is it automatically computed and entered into the MCDU (FMS)? or is it on one of the charts? I have Navigraph subscription but I am not sure if I can post the charts on here... I have attached a copy of a flightplan I did last week just in case it's on there and I missed it. I don't want to include IAF into my list without understanding how I find that info. Wayne Link to comment Share on other sites More sharing options...
Ken Q Posted June 9, 2022 Share Posted June 9, 2022 (edited) Hi Wayne The IAF can be found on the Approach Plate of you destination airport. On Navigraph Charts click on the destination airport in the flight plan summary across the top. Click on "chart list" "APP" then choose the approach that you want. I'm looking at the ILS or LOC plate for KRDD RWY 34. At the outer end of the arrow it identifies the initial fix (IF) "DIBLE.". Halfway along the arrow "LASSN" is identified as the (IAF). On the horizontal plan it is identified with an "X" along with altitude and step-down instructions. The same info can be found on Skyvector as well. Hope this helps.

Gulfstreamtwo Posted June 10, 2022 Share Posted June 10, 2022 (edited) "IF" denotes an intermediate fix, while "IAF" is an initial approach fix. An IF, if designated as such in the procedure, sits between an IAF and the final approach fix or "FAF".

Gulfstreamtwo Posted June 10, 2022 Share Posted June 10, 2022 (edited) To add to the above, in the sample of the linked Jeppesen chart, you can see DUMBA is both an IAF (when approaching from the Oakland VOR) and an IF when approaching from MEHTA or MENLO. AXMUL is the FAF (Indicated by the Maltese cross in the profile view) no matter where you begin the approach.

We've all had that experience where what we were looking for was right in front of us and we just couldn't see it. Glad the community was able to help. 1 1 Link to comment Share on other sites More sharing options...
