Enter glide as normal.
Enter descending turn at 30 deg AoB maintaining normal gliding IAS.
Increase to 45 deg AoB turn attitude; progressively increase nose-down pitch attitude to maintain normal gliding IAS.
To recover, reduce to wings level and carry out a normal recovery from a descent.
In a 45 deg turn, the stall speed is only 1.2 x the 1 g stall speed; thus a PA28 would stall at around 68 mph rather than 57 mph, well below the normal gliding speed of 85 mph.
Increasing the IAS above the normal gliding speed is totally unnecessary in a 45 deg AoB gliding turn and would cause an unreasonably high RoD.
No special 'lists', 'aims' or other complications - this is a very straightforward exercise which requires slighter greater skill than a normal descending turn - the principal assessment requirement being to ensure that the applicant appreciates the reduced margin between the gliding speed and increased stalling speed and controls the a/c attitude accordingly.
