...a standard rate turn would give an excessive angle of bank, particularly in a century series fighter...
Yes, indeed.

For example, to have performed a rate 1 turn, in level flight in the cruise, in one passenger aircraft in the BA fleet not so long ago, would have required a bank angle of 73°, and pulling 3.23g.

Even a half-standard rate turn would have involved a bank angle of 58°, and pulling 1.89g.

Probably why we didn’t ever attempt them in the cruise!

In fact, most jet passenger aircraft will not attempt a rate 1 turn, in level flight in the cruise, as anything cruising around M0.85 and FL350 would need to use a bank angle of about 53° and pull around 1.66g.

...to fly it, try an angle of bank equal to 10% of the airspeed +7...
Well remembered; a formula still being used, which works well for any aircraft when flying at more modest speeds.
