I’m reopening this topic because I’ve been doing some “research” about the ILS Z on runway 15 of SBGL…
For a few days I listened to the communications from Rio control and also from the Galeão tower and I realized that the use of ILS Z is more common than we think, it is a standard procedure for runway 15 on Galeão. Several airlines use this procedure for landing, including international companies…
I know that we already have some topics dealing with this and with a solution already presented, but I ask you to reconsider the possible implementation of this procedure in MSFS to make the reality experience more simulated.
the point is not, that this procedure doesn´t exist - this procedure exists for sure and will also be used as you have discovered. The point is, that this procedure can´t be coded for the data as an ILS approach due the ARINC424 standard rules (missed approach starts prior the runway threshold and follow not the runway heading).
Compare the ILS-Z 15 approach with the ILS-R 15 approach:
Can´t be coded:
Can coded and therefore included in the FMS data:
So, that´s nothing what we can reconsider … that´s simple coding rules. But you can fly this approach without any issue, as in the reality. So, there is no stop to fly it … but right, it´s not a “one button” press.
