TERPS Circling Approach

[extricate]

Hi,

For PAN-OPS, it is very clear that the maximum manoeuvring speed is 205kts for a CAT D aircraft. An aircraft should not exceed 205kts for the whole approach.

For TERPS, it is referred to as threshold IAS which is vref, or 1.3 Vso at max landing weight. For a CAT D aircraft, it should not exceed 165kts. So, how do I know what is the maximum manoeuvring speed to fly the approach, from downwind-base-finals if it only states the maximum threshold speed? Does it mean I have to maintain max of 165kts throughout the approach?

Thank you

Either that, or if your aircraft has a circling speed higher than the max Vref for the category then you should use the minima for the category you are now in.

The maximum speed is determined by which procedure is being used; which chart.
These speeds relate to turning performance within the safe area.
The geometry and safe areas for PANS-OPS and TERPS differ.

4R, Link broken; was this what was expected?
