ETP / ETOPS, or SETOPS

Depending on the aircraft selected, Dispatch will display the option to configure either ETP / ETOPS (Equal Time Point / Extended Twin-Engine Overwater Procedures) or SETOPS (Single Engine Turbine Operations).

1. PSR (Point of Safe Return)

PSR provides the pilot with the most distant point the aircraft can go to and be able to return safely to the departure airport with alternate and reserve fuel. Click the PSR box to add a grey dot on the route showing the PSR. In the example below it falls between GITLE and DIALO

Hover the mouse cursor over the dot on the route to see an explanatory label for the point:

After clicking the PSR box it is also included in the Navlog, as highlighted in the example below:

2. ETOPS (Extended Twin-Engine Overwater Procedures)

After entering at least 2 ETP Alternate airport ICAO codes in the ETP/ETOPS Airports field, click the box labeled ETOPS to display ETOPS circles(s) on the map display. If ETOPS information cannot be shown, an error flag will be displayed with details.

Click the "enlarge" (arrows) button in the upper-right of the map display to see a larger view of the route with the ETOPS circles:

NOTE: If the aircraft's ETOPS has not yet been configured, click the blue "Configure ETOPs for this aircraft" link, or click on the Aircraft page and select the aircraft.

On the Aircraft page, enter the parameters for the aircraft's ETOPS Calculations. To add an additional ETOPS ring, click "+ Add new range" in the ETOPS Calculations section:

After making the changes, be sure to click the green "Publish Changes" button at the lower-right of the page so that the changes are made available to everyone using the account.

3. ETP (Equal Time Points)

After entering at least 2 ETP Alternate airport ICAO codes in the ETP/ETOPS Airports field, Equal Time Points are calculated using the Stepping Stone Method. Diversion calculations are made between each ETP alternate pair for for Medical (at altitude), Depressurization, and One Engine Out. 

Medical - is a diversion at altitude.
Depressurization - is rapid descent to predetermined altitude (standard is 10,000’).
One Engine Out - is the failure of one engine with a possible decrease in altitude depending on aircraft performance.

The resulting calculations are shown in the Navlog, and also as dots on the route line in the map view.

NOTE: If the aircraft's ETP has not yet been configured, click the blue "Configure ETOPs for this aircraft" link, or click on the Aircraft page and select the aircraft.

4. SETOPS (Single Engine Turbine Operations)

SETOPS enables European commercial operators of single-engine turbine aircraft to easily comply with EASA regulations by quickly generating compliant routes. The SETOPS analysis generates a route map showing risk periods and airport glide circles, as well as a detailed risk analysis that calculates risk exposure time and cumulative risk factor, colored green or red to indicate compliance.

The route map is shown on the Flight view and is also included in the Briefing, along with the detailed risk analysis.
