Will they finally make it a regulation so that pilots are required to ACTUALLY know when they are on duty every day?

They should put it in the big book of FARs in part 135 that a flight crew member's rest period must be "(1) continuous, (2) determined prospectively (i.e., known in advance), and (3) free from all restraint by the certificate holder, including freedom from work or the present responsibility for work should the occasion arise."

If you’re required to be on call all day for work, they shouldn’t be allowed to call you at midnight to get up and go fly 14 hours. That isn’t safe yet it’s not forbidden under part 135. All 135.267 says is that they,”must provide for at least 10 consecutive hours of rest during the 24-hour period that precedes the planned completion time of the assignment.”
Based on the vague wording, they could call you at 2am and tell you that you weren’t at work for the last 10 hours so you’ve had rest. It doesn’t matter if you we’re just laying down after being awake for 16 hours ready to go waiting for a call.

These operators aren’t going to stop what they’re doing until 135.267 says what all the letters of interpretation say.
