I usually "fly" with flightsimulator (FlightGear, because is O.S. and freeware). I try to make the fly real as possible, and I try to use IAP, is this procedure correct to approach RWY 28 of LSZH Zurich Airport?

enter image description here

I'm on FIX AMIKI, I can use this IAP after complete STAR

AMIKI then KLO then 84° and at D16(16 miles distance from KLO) i take 275° and allign to ILS?

Or I make all/something wrong? How did you proceed to enter in RWY 28 ils? Thanks

First of all, what you show is not a STAR. There are several STARs at LSZH that end at AMIKI (NEGRA 2A, RILAX 2A, TRA 2A). What happens after AMIKI is the approach transition.

There are 3 ways to get from AMIKI to the ILS for runway 28:

  • Radar Vectors: ATC will give you vectors onto final approach. This would most likely happen in reality

  • RNAV Transition: There is an RNAV transition from AMIKI to RAMEM called AMIKI28 transition:

    AMIKI - ZH382 - ZH450 - ZH452 - ZH454 - ZH456 - ZH458 - ZH460 - ZH464 - RAMEM

    If your aircraft is RNAV 1 capable (GNSS or DME/DME required), this would be the preferred transition to fly. From RAMEM (the D10.3 point on your chart), you can start the ILS approach.

  • Radio-based Transition: This is what you show on your ILS chart. You would only fly this if you don't get radar vectors and are not RNAV 1 certified.

Regarding your description of the procedure: you have a problem when arriving from ZUE at KLO. You cannot directly turn outbound to 084° because the change in course is too much. ICAO PANS-OPS only allows up to 30° turns when aligning for the reversal procedure:

Unless the procedure specifies particular entry restrictions, reversal procedures shall be entered from a track within ±30° of the outbound track of the reversal procedure. However, for base turns, where the ±30° direct entry sector does not include the reciprocal of the inbound track, the entry sector is expanded to include it.

(ICAO Document 8168, Vol 1 §4,

Therefore, what you'd have to do is enter the hold at KLO and use the hold to align yourself with the outbound track of 084°. Then you continue the procedure as described.


I think the procedure envisions a teardrop entry into the holding pattern at KLO to reverse your course and get back to KLO in a position that you can commence the procedure track to the east.

So, the steps would be:

  • ZUE
  • KLO
  • outbound on a 234 track for 1 minute (the teardrop entry)
  • Right turn & inbound to KLO on the 084 inbound course
  • Outbound to the KLO 084/16
  • Right turn & intercept the ILS

  • $\begingroup$ @MichaelHall I didn't claim I thought it'd be fun! Yes, definitely, vectors to final, thank you. $\endgroup$

    $\begingroup$ I agree with @Bianfable's answer, which explains the other options & why these steps would be required. My answer elaborates on his 3rd point. His early observation that radar vectors is what you'd expect in reality, is spot-on. $\endgroup$

  • $\begingroup$ Thanks, why one minute? I cannot find in my chart $\endgroup$

    $\begingroup$ @elbarna The one minute is just the standard way of flying the teardrop entry into a holding pattern. You won't find it on the chart. Technically, you could fly any entry into the hold as long as you stay in the protected area, but a teardrop entry with a one minute leg is the recommended procedure in this case. $\endgroup$
