Gents,

The Australian 'final approach fix' for an ILS is defined as coincedental to that of the LLZ maltese cross on the Jepp chart, thus, usually around 5nm.

Further, the Cat D speeds are 250 - 185 Initial, 185 - 130 Final ( ICAO, fair enough )

For the B773ER. the Final flap limit speed ( 30 ) is 180kts.
The Company and Mr Boeing's standard profile is, of course to select final flap at G/S intercept.

Here's my concern.....if G/S intercept begins at 10nm, from 3000'...how can we be complient with our speeds for the remainder of ite Initial approach, until Final segment starts at 5nm?

Am I missing something here? ( The Aussies have decided to depart from ICAO for some reason, and my aircraft doesn't fit their formula, as far as I can see)

Any help you fellas can offer would be greatly appreciated

Cheers

Aus AIP allows you to reduce speed before the FAF. I know 5 miles might be stretching the friendship but if that is how your company flys it will just have to be good enough.

Note 2: Speed reduction below the initial segment speed
range is permitted to enable the final approach speed to be
achieved prior to the commencement of the final segment.

:ok: Hey thanks Maxwell, I guess that's it then, problem solved.

Ops normal, and the square peg is now firmly in place downunda.
