Ah yes, radio range. Lost orientation procedures in the link trainer and a syllabus including flying under the hood in the back seat of a Harvard at 3-4000 ft in summer turbulence in Southern Saskatchewan, (Regina range).
On squadron, once a year, to renew our instrument ratings, we had to demonstrate competence in the SJRA, (standard jet range approach), under the hood in the T-33. The fact that on the squadron equipment (CF-100), we rarely if ever used the range made no difference. Not many of the SJRAs were anything to be proud of but you had to complete one that you could have landed from. It was not really much of a procedure for a jet. An NDB approach was a lot more practical but the range approach had to be done and you could not select ADF to use the pointer, A and N expertise had to be demonstrated long after it was of much use.
