Does it directly mean the minimum altitude for holdings on VOR or NDB or can it be interpreted in another way? Because MHA 4500 information for the holding is given on the right side. This picture is taken from LTBR airport's ILS Z or LOC Z Rwy 25R Jeppesen chart with page number 11-1.

  • $\begingroup$ I didn't mention anything like that in the question. I'm also looking at the Jeppesen manual, but I couldn't see a one-to-one correspondence and wanted to ask this question because I felt the need to get approval for an equivalent explanation. $\endgroup$

This number is a Crossing Altitude for the initial approach course / racetrack.

Altitude/FL indicated by state source as recommended will be charted without over-bar and under-bars.

The MHA, on the other hand, is part of the missed approach procedure.

  • $\begingroup$ @pilot162 Are you asking about something other than the ILS Z as charted? It is certainly possible to have other procedures or airways associated with the VOR, but the Crossing Altitude for the ILS Z procedure wouldn't be relevant to other uses. $\endgroup$ Oct 13, 2022 at 23:01
  • $\begingroup$ Adjusted to initial course, not intermediate. $\endgroup$ Oct 13, 2022 at 23:12
  • $\begingroup$ Let me summarize if I got it right. "4500" means the recommended VOR crossing altitude for performing the ILS procedure. Am I right? $\endgroup$

  • $\begingroup$ @pilot162 Yes it is as simple as that. If there is any lingering question about the procedure, it would be necessary to use the government chart or text rather than Jeppessen. $\endgroup$ Oct 14, 2022 at 14:53
