Summary

Description (en) modifications as follows:

Once into the area, the controller directs a perpendicular path to the app course.

At 1.5 nm from app course, "Make half standard rate turns. Turn <left/right> heading <toRwyHdg>".

A few seconds latter "Approaching glidepath. Begin descent. "

A bit of math to substantiate that:

A 90 deg half standard turn takes 60 secs = 0.017 h

At some 110 kts IAS results an arc of 110 x 0.017 = 1.87 nm

Such arc is rxPI/ 2 thus r = 2 x 1.87 / PI = 1.2 nm.

Adding some secs to configure attitude, we have 1.5 nm.[1]
