Introduction
Route Building - Intermediate
This topic will be comprised of a step-by-step walkthrough showing how to build a practical route, including consideration of rules, the method of efficiency. The Intermediate Route walkthrough will show functionality required for an international route within Europe.
We estimate that this will take 5 minutes to complete.
Introduction
This topic contains a process showing how to build a practical route, including consideration of rules, and the method of efficiency. The Intermediate Route process shows the functionality required for an international route within Europe.
Detailed Explanation
Route Building - Intermediate
Items covered in Intermediate Route Building:
- Setting a flight level range for section of a route
- Must not use field
- Accessing IFPS Compliant Routes0.
Click the LETAK+CY+E Q848 list item.
In this example, we will change part of the planned route's altitude.
Click the LIVBA+CY+E Q848 list item while keeping the 
key pressed.
Once you click on the first waypoint you want to change, hold the SHIFT key down and click on the last waypoint you want to change. Everything in between those two waypoints will turn yellow.
Click the LETAK+CY+E Lower Flight Level input field.
For the highlighted section, we want to limit the flight level range.To start, click in the lower flight level range input field.
Enter 310 into the LETAK+CY+E Lower Flight Level field.
We want our minimum altitude for this segment of the flight to be FL310 or 31,000 feet.
Press the 
key.
Once you have entered the minimum altitude, press the TAB key which will take you over to the maximum altitude field and also copy your inputs for the entire highlighted area.
Enter 350 into the LETAK+CY+E Maximum Flight Level field.
Enter our maximum altitude as FL350 or 35,000ft.
Press the 
key.
Pressing the tab key again will copy the value into all highlighted sections of your route.
Click the Apply button.
Once finished, select Apply so the changes can be updated while you finish your flight plan.
HINT
If you need a segment to be at a specific altitude, be sure to set both your minimum and maximum fields to the same value.
Click the Must not use input field.
In this example, we will avoid a FIR while building a dynamic route.
Enter FIR ESAA into the Must not use field.
In the Must not use field, we will avoid the ESAA FIR.
HINT
Rules are specified as follows: Waypoints - add the name of the waypoint, e.g.: YYZ+CYAirways - add the name of the airway, e.g.: YQT+CY J500 YOW+CYRestricted Areas - add the keyword (AREA) and the name of the restricted area, e.g.: AREA CY:609MFIRs - add the keyword (FIR) and the name of the flight information region, e.g.: FIR CZYZCountries - add the keyword COUNTRY and the country code, e.g., COUNTRY CA Rules are separated by forward slashes or commas.
For example: YYZ+CY, YQT+CY J500 YOW+CY, AREA CY:609M, FIR CZYS, FIR CZUL, FIR CZWG
Click the Generate button.
Click the Apply button.
You can see on the map screen that the route optimizer follow the rule of avoiding the ESAA FIR and built a route around it.
Once you select Apply from the route screen, the route will save so you can continue planning.
In our final example, we will show you how to request IFPS routes.
First, after you have computed an initial route you can go into the Route screen and select New.
Click the New button.
HINT
IFPS Routes can only be requested after you have computed a flight plan so it can pull accurate times in order to offer IFPS route options.
Click the 
button.
To request IFPS routes, select the small green arrow to the right of the route field.
Click the IFPS-1: ARS N623 BEDLA N866 NEGIL M852 LALIL... list item.
Available options will appear in a list. You can select a route directly from this list to have it pasted into the route box.
You can also request IFPS routes again if you need to refresh the list.
Click the Generate button.
Click the Apply button.
The selected IFPS Route appears in blue on the map screen. Apply to continue working on your flight plan.
ATTENTION
The N-FP system may not always be able to find a valid route option. A message is displayed in the Status Bar if no IFPS routes are available.
