Hello, the ILS08 is missing within aircraft boxes.
I did see this post ( Missing procedure for NCRG - #2 by NAVData ) and I’m not sure what the coding regulation is referring to here. But to respond to the post, the missed approach for the ILS is not MA08 (where you would break off the approach for a LOC). It’s the DA, which you would initially fly runway heading and then join the 350 off RG when able.
It SHOULD be in the aircraft. How do I know? Because I’m an airline pilot that just loaded the ILS08 in my box and flew it. So please fix it. You cannot load the loc and “fly it like an ILS” if certain aircraft (like an Airbus) won’t give you the glideslope.
Hi,
This is nothing that must be fixed. As I wrote in the reference post, the missed approach doesn’t follow the runway heading and begins before the runway threshold. That means it “breaks” the glideslope before. Jeppesen codes such situations as LOC only for the FMC/S. That does not mean you can’t fly an ILS approach because the GS antenna is, of course, in place and also receivable (possibly not by an Airbus, but in a Boeing, a G1000, …).
Here from the Jeppesen charts - the missed approach point is at D2.5(7)/INO (MA08):
Richard, MA08 is the LOC missed at 840’. Not the ILS missed. Yes you still turn left, but the missed for the ILS is 380’/400’. Bottom line is MA08 is irrelevant to this conversation as it’s irrelevant to the ILS.
There’s plenty of approaches that have a left or right turn that isn’t at 200’ that I’m sure you guys have coded as ILS in the databases.
As far as receiving the GS, the plane receives it, but if you only load a LOC (as that’s all Navigraph lets us do), it’s going to give you F-GS, a computed path and not an actual ground based signal. In the Boeings it’s IAN. In Garmin it will be their custom vertical guidance.
Either way, you guys should still add it. It’s a valid approach. It’s not an airline specific approach. If it was we would have an airline specific chart, but we don’t. We have the exact same Jepp.
That´s what I have written/marked… When you code the LOC portion, the M represents the non-precision missed approach point (MAP).
A word on the coding rules of the different ARINC424 revisions:
The Missed Approach Procedures for the NCRG ILS procedures require a turn away from the final approach course prior to the runway. Historically, ARINC424 coding rules required that an ILS approach be coded to the runway, so they could not adhere to the source documentation and still honor the ARINC424 coding rules. As a result, these procedures, and a few other ILSs (ex OLBA, …) with the same design, were not captured in the source data. Therefore, they coded only the LOC portion.
Again, it could be that:
You are using a newer ARINC424 revision (20+)
You are using tailored airline records
We use revision 18 (and partly newer versions, but not for the approach parts), and here Jeppesen codes such designs as LOC (according to the charts, it´s an ILS DME or a LOC DME approach).
