Thank you for quoting the phraseology guide. In the IFR guide, it states that "If you are unsure, if something is unclear, or not what you expected, it is important that you ask for clarification."digits_ wrote: ↑Thu Jun 20, 2024 3:23 pm Page 26 in the VFR phraseology guide lists it as an example: https://www.navcanada.ca/en/vfr-phraseology.pdf
As well, it states that "A pilot may, at any time, read back a clearance in full to seek clarification."
In the TC AIM, it states "If there is any doubt as to what is required, clarification should be obtained from air traffic control (ATC)."
So, those statements indicate that if there is any confusion, the pilot is to seek clarification from ATC. As numerous controllers have said to you, in 99.99% of the cases that "balance unchanged" was used, there was no issue. In the other 0.01%, the pilot asked for clarification, which is the expected (and required) process, same as any other confusion or misunderstanding.
The fact that the OP was confused with what it meant, and then sought clarification seems to be exactly what was supposed to happen. Keep in mind that OP stated that they were not IFR rated, so they had no context for what the controller was instructing IFR aircraft to do. They were just curious what it meant. No different than a VFR pilot being curious about what a SID or STAR is. As a non-IFR pilot, they have no need to know what "balance unchanged" means when they hear someone being issued an IFR clearance. (As per MATS, "Balance unchanged" is only used with IFR clearances by the way).digits_ wrote: ↑Fri Jun 21, 2024 7:28 am I have some trouble understanding why the ATC folk here seem to be defending the statement so much. There's a report that at least 2 pilots (OP and me) did not understand what the phrase meant when we first heard it and a 3rd was looking for a reference. And the reply is 'it's clear language!'. Well ok then...
I'm not sure how you think this is such a big issue. Transport Canada has delegated NavCanada to write MATS (which in itself is based on the CARS and AIM), and felt confident enough to approve the use of "balance unchanged." So, if you have a complaint, take it up with Transport. They seem happy enough with the way we're doing things.
