Not a moderator input, just personal observation:
I have performed a .297 ride almost every year since 1994.
I have never been asked to do anything that wasn't a specific instrument activity. Approaches only, missed approaches, and a hold.
I have, from time to time, been asked to do a .293 in the interest of time, which can be substituted for the .297 ride, and is actually a shorter ride by about 30 minutes.
The Part 121 world is the same way.
I'm not going to argue the semantics of the wording in Parts 135 or 121 that allow you to substitute what for what and in what circumstances. I'm simply going to tell you that I've had more checkrides than I can count, including multiple type ratings, feds on jumpseats, Check Airman authorizations, checkrides in the actual aircraft as well as the sim, you name it, I've likely done it, and I have never, ever, ever had anyone, including a Fed, from any FSDO (and I've flown for companies based in N.Y., FL, GA, TN, TX, MI, and MN) try to tell me that I had to perform any kind of stall or steep turn or anything else on a .297 ride except instrument competency maneuvers.
You can argue semantics all day long, but reality rules, and the reality is that no one expects a stall on a .297 ride. Not that it CAN'T be given, but simply that no one does, unless they're on a fishing expedition because you've otherwise screwed the pooch with your instrument maneuvers and your basic flying skills are in question.
I'm going to throw the BS flag on this one. A 121 PIC proficiency check IS an ATP and a type rating check all rolled up into one. And, all of the stalls cannot be waived. Likewise, a Part 135 proficiency check by rule includes all the maneuvers on either the ATP PTS or the Commercial Pilot PTS depending on the operations specifications for the operator. I've given a few hundred checks, both 121 and 135, and I certainly never saw any expressions of surprise when steep turns and a stall series was asked for.
Your statement that you've only done instrument maneuvers during your many .297 checks means you've never done an aborted takeoff, a V1 cut, a balked landing, a visual no-flap approach, or a simulated brake failure. I find this very hard to believe.
BTW, a .293 check can't be substituted for a .297. It's the other way around. And, the reason a .297 can be substituted for a .293 is because .297 contains all the maneuvers required by .293 plus the additional instrument stuff.
