“N123A amended Level and Speed clearance”

Revised Clearance Details

• May occur prior to entering or exiting Oceanic Airspace

• Level, Mach or Routing

• The term REROUTE is only used for routing

• For a Voice Route revision ATC/Radio Operator will state:

– “ROUTE HAS BEEN CHANGED” or “AMENDED ROUTE” or “RE-CLEARS”

• “N123A AMENDED ROUTE CLEARANCE, SHANWICK OCEANIC RE-CLEARS

N123A AFTER 57N 020W TO REROUTE VIA 58N 015W, GOMUP, GINGA”

Entry Point Change

• Crews have sometimes had ATC intervene because they failed to pick up the fact

that only the entry point has changed. This is why ATC or the radio operator

should use the element change statement when in first contact with the crew.

23

“N123A Oceanic Clearance with an Entry Point Change”

Remember the lack of hearing REROUTE does not mean nothing has changed

ATC has already figured where you will be at the indicated time.

So what we have seen is ATC providing as much help as possible for crews to

identify changes to what they were expecting.

CPDLC has given us additional help.

Now it’s up to us to pay attention!!!!!

All is not always perfect with CPDLC

Does ADS-C keep us on Clearance?

28

Does a Radar Detector protect you from speeding?

Predicted Route Group

•Latitude at next wpt

•Longitude at next wpt

•Altitude at next wpt

•ETA at next wpt

•Latitude at next +1 wpt

•Longitude at next +1 wpt

•Altitude at next +1 wpt

Every Periodic Report will contain your

current Latitude/Longitude

29

Vertical Rate Change Event Is triggered when the aircraft’s vertical rate is either less than or greater than a parameter defined in the contract.

Altitude Range Change Event Is triggered when the aircraft’s altitude exceeds the altitude ceiling or floor defined in the contract by the ground system. .

Lateral Deviation Change Event Is triggered when the aircraft’s actual position exceeds a lateral distance parameter from the aircraft’s expected position on the active flight plan.

So lets look at how we can use old school procedures to protect us

from causing errors.

• Use of and Preparing the Plotting Chart

– Required (Service volume gap of >725NM)

– At a Minimum

• Cleared Route

• 10 minute check

• Clearly depicted ETP’s

– Plot the Tracks

Techniques to cleanly capture Oceanic Clearance

and validate against the Flight Plan

34

OCEANIC CLEARANCE

• Update the Navigation System if needed

• Validation of the Navigation System after modification

• Approaching the Oceanic Entry Point

• Passing Waypoints

• 10 minute Check

35

• Use a reroute checklist

– Modify your Flight Plan to reflect the new clearance

– Does this affect your fuel planning?

– Does this affect your selected alternates?

• Are they closer or farther away from your route?

– Are your ETP’s still valid?

– Do you need to calculate new ETP’s?

– Modify your Plotting Chart for route, and plot new ETP’s

– Verify that the FMS was modified correctly using the same technique that was used for the original load

• Check waypoint, Course and Distance for each leg, comparing FMS to Flight Plan

36

REROUTE

When Comparing FMS Course to Flight Plan

• Ensure the MC on the flight plan is initial MC=initial to √ FMS

• MH on flight plan should be Average corrected for winds

MH=A for D.R.
