I see no mechanism on how not saying the word "takeoff" would cause an accident
How about asking the tower to confirm if you're "cleared to go", instead of "cleared for takeoff" and both they and other (maybe foreign) pilots not having a clue what you're talking about?
The AIM says that all transmissions should start with the call sign
Looking very carefully, I can't find it to say that. Do you have a part/paragraph reference in mind?
The " Cleared to Go" call is for when you are acknowledging the ATC call "ABC cleared for takeoff". Uncertainty about whether you are cleared for takeoff or not is a different situation and one that doesn't come up that often.
Your question got me thinking though and it is something I don't specifically address in training, but should. For the record if I am unsure of the status of my clearance then I would say "Confirm ABC is cleared for takeoff". In this case I think one should say the word takeoff, because we are not, as in the first case simply acknowledging a call which is fully understood, this is a case where uncertainty exists and so there must be absolutely no doubt what the issue is. Therefore the most unambiguous way would to to say "takeoff" in your transmission.
The AIM does not specifically say "put the call sign first" but every example they provide has the call sign in the front, therefore the implied direction is just that.
I think that you are never to old or experienced to learn something new. One of the things I like about reading Avcanada is it often makes me think about stuff I took for granted. On reflection your comment on the "cleared to go" is right, it is not the best way. Therefore I am now going to tell my students to acknowledge the call from ATC "ABC cleared for takeoff runway 18 " with the response "cleared for departure 18 ABC".
"Departure" is a ICAO recognized term, is unambiguous, and avoids you saying "takeoff".
For the call when you are ready for takeoff I still like "ABC 18 at Alpha, Ready". Of note I am in the habit of adding the taxiway I am at in addition to the runway because the field where I mostly fly has staggered taxiways on both sides of the main runway, so confirming which taxiway you are at reduces confusion, especially when there are several aircraft "Ready". On runways where there are only taxiways at each end then the runway number alone is all that is required.
The "Primacy" learning factor really applies to radio work as bad habits developed early are very hard to break. ( My current Alberta trained student still occasionally sticks in the stupid " conflicting traffic please advise" call despite my ruthless mocking of this silly practice).
My
personal opinion is that the ready call that I have described above is the best most efficient call and should be taught to every pilot starting at the first ab initio lessons.
Still I want to emphasize that my opinion represents one data point and should be critically examined like any other advice on an anonymous bulletin board. I will acknowledge that this is not life or death stuff and so I do not wish to imply that someone who wants to say "ready for takeoff" is doing something "wrong" or "unsafe" simply that I think there is IMO a better way.
