Hi,

Can I confirm that point 8 in the attachment is the FAF for precision appr (Which is also the start of G/S interception)? The maltese cross is the FAF for NPA?

Normally, at the top, approach charts will have a Crossing Altitude, in this in relation to the FAF for precision approaches?

Thank you

#8 is the precision approach FAF, BRETT is the NPA FAF. 8,000 is the GS intercept altitude or the NPA altitude to maintain until BRETT. I don't see where any altitudes are missing.

The precision FAF is the point where the G/S intercept altitude intercepts the the glide slope, by definition.

Jeppeson:

FINAL APPROACH FIX (FAF) — A specified point on a non-precision instrument approach which identifies the commencement of the final segment.
FINAL APPROACH POINT (FAP) — A specified point on the glide path of a precision instrument approach which identifies the commencement of the final segment.

Very misleading thread title since you're talking about an approach plate, so nothing to do with SIDs and STARs.

FAA AIM says this about PFAF,

2. The ILS glide slope is intended to be intercepted at the published glide slope intercept altitude. This point marks the PFAF and is depicted by the ”lightning bolt” symbol on U.S. Government charts. Intercepting the glide slope at this altitude marks the beginning of the final approach segment and ensures required obstacle clearance during descent from the glide slope intercept altitude to the lowest published decision altitude for the approach. Interception and tracking of the glide slope prior to the published glide slope interception altitude does not necessarily ensure that minimum, maximum, and/or mandatory altitudes published for any preceding fixes will be complied with during the descent. If the pilot chooses to track the glide slope prior to the glide slope interception altitude, they remain responsible for complying with published altitudes for any preceding stepdown fixes encountered during the subsequent descent.
