Clearance on a SID

Post by BEFAN5 »

I have begun getting a variation in my clearance and for the life of me can't figure out the difference.

Normally: "C-AAAA, cleared to the ABC airport via the ZZZ1 Departure squawk 8383." I normally just read back the squawk.

Lately: "C-AAAA, I'll need you to read this all back this time; cleared to the ABC airport via the ZZZ1 Departure, DIRECT squawk 8383"

Thoughts ideas? At first I thought it had something to do with in the event of a comms failure, I'd fly direct to the destination rather then the FPR, but m flight plan is always filed direct.

I believe, to the letter of the law, the only requirement is to read back the assigned code. However I know some airports (Calgary), have a requirement listed in the CFS for the pilot to read back the assigned code, runway, and SID.

As for the routing, you do need a routing after the SID in order to get you to your destination. We use the phrase "flight planned route", however using "direct" would also work.

As for the difference in your case (your flight planned route is direct), I don't see any difference between the use of "flight planned route" and "direct". In either case I would expect you to fly the SID, whatever that may be, and then point your nose towards your destination.

That's weird. If it's not a busy frequency I'd ask why the full readback. If it is busy call the tower supervisor and ask.

Occasionally the flight strip will come through with a notation requiring a full readback of the routing, usually because something's been changed by flight-planning.

Recently, however, we've been getting more coming through requiring that readback even when the routing is simply direct. I don't know what causes this, and haven't been able to get an answer on it yet (we've also had VFR flight strips come through requiring a readback of the routing... this leads me to believe it's a glitch)

Since we don't generally look at the routing on a strip before you call for clearance we don't go asking flight planning why the readback is required ahead of time. When you call and we look at the clearance, it's just quicker to get the "direct" readback than to go looking for reasons for it.

Thanks... The first time it happened the controller said something along the lines of "I guess you need to read this all back....?" sounded a little confused himself. He had a few other aircraft calling for clearance at the same time so I figured I'd save the "do you have time for a question" for another day.. Or a lazy layover and avcanada... haha

From ATC MANOPS

You may omit requesting a readback for an initial IFR clearance issued by a ground or clearance delivery controller provided:

a: no changes have been made to the originally filed flight plan
b: the clearance is issued by referring to a machine printed strip or a video display of the flight plan
c: the clearance includes a published SID
d: no alternate instructions are included in the clearance; and
e: there is no apparent misunderstanding of the clearance contents.

the associated note says
Omission of a readback may be used only for the initial IFR clearance issued to a departing IFR aircraft. Departing IFR aircraft will acknowledge receipt of an IFR clearance by responding with the aircraft call sign and the assigned transponder code.


Hope that answers your question, we could have an equipment problem that would be transparent to you that would require us to get a full readback.
