5-9-1 requirement to issue an altitude compatible with an NPA or an
altitude below the G/S for a PA.

"b. For a precision approach, at an altitude not above the
glideslope/glidepath or below the minimum glideslope intercept altitude
specified on the approach procedure chart.
c. For a nonprecision approach, at an altitude which will allow descent
in accordance with the published procedure."


That's swell, but you said controllers were supposed to step down to the
altitude shown on the chart. Where is that requirement?



Even if he was vectored onto "final" 50 miles out, 5-9-4 leads to 5-9-1.
This stuff is written to make the IAP flyable, not to provide loopholes
for controllers. ;-)


I think you'll find that 5-9-4 follows 5-9-1.

I guess it depends on the definition of "is."~

Great observation! Also, there is the issue of context:

5-9-4 Arrival Instructions
Issue all of the following to an aircraft before it reaches the approach gate:

"Approach gate" sorta ties 5-9-4 to 5-9-1.
