compulsory reporting points: what points do you name for EST and NEXT?

[VetsJetsnGuns]

In a position report you give three waypoint names.
In a string of five waypoints named A, B, C, D and E, with only A, C, and E being compulsory reporting points:
in your position report, would you mention B and D at all?

AIM 5-3-2.d leaves me with questions.

Jeppesen (INTRODUCTION, pp. 55, enroute chart legend) shows waypoints as either "compulsory reporting points" or "non-compulsory reporting points."

Is the answer different for different regions/FIRs?

PLEASE cite your answer.

VetsJets,
just curious, but when I did the U.K Area Procedural control course in 1986, a/c had to give 2 positions;- where they were, and the estimate for the next compulsory reporting point.
What is the third one? Is it (..........), next?
On request reporting points were, i believe, ignored, unless ATC instructed otherwise.

[VetsJetsnGuns]

yes, the 3rd one is the "next"

[BuzzLightyear]

I agree with Zooker on this.

If your route has compulsory points then you report where you are then the estimate for the next compulsory point. The estimate or a report at a non-compulsory point would only have to be given if requested by ATC.

It would only be requested if the ATCO wanted an intermediate point to get a pass to climb or descend, to prove a separation or possibly if the time elapsed between the compulsory points was greater than that allowed for reporting action for operation normal checks.

Are you talking about domestic reports or oceanic? If oceanic then you will have three positions in the report i.e. Present position, estimate and coords for the next position followed by the next pis after that. All positions will have been included in your oceanic clearance and used. Any intermediate positions not included in the clesrance should not be given unless specifically requested. In oceanic terms, all positions in a clearance are compulsory positions

An example of an acft flying through oceanic airspace with no ADS/CPDLC:

"BAW43, crossed position 'AAA' 1200 F370, estimate position 'CCC' 1255, 'DDD' next"

In this instance, ATC will not be able to verify the flight status of the acft for almost an hour, but our requirement is to ascertain ops normal every 30 min. If there is an intermediate waypoint that will reduce this gap that is not a compulsory reporting point ( i.e FIR boundary etc.), atc may reply:

"BAW43, Copy estimates, report 'BBB' FL370".
