Route format and typical gradients
For example N0140F070 ENTO DCT SKI/5000 5930N01045E ENGM. A 3° descent is about 318 ft/NM; departures are designed for at least 200 ft/NM (3.3 %). Your aircraft’s real climb comes from the AFM.
What the map shows
Highest terrain per square: our own figure from the terrain data, highest point + 300 ft for unknown obstacles, rounded up to 100 ft. Not an official MEF. Not shown: airspace, airways, obstacles and IFR points for Norway, Sweden and Denmark (no licensed data yet). Not an official VFR or IFR chart.

Route, markers and notes are saved together as one route.
Optional settings. They change the profile when it shows Climb and descent, and some of them (MSA, corridor, clearance) in every view.
Weather is drawn when the profile shows Climb and descent. For forecasts, use the Windy button on the map.
Adds the approach after the last en-route point. Distances in NM, altitudes in feet. Leave out what you don’t use.
IFR minimum level (SERA.5015): at least 1000 ft above the highest obstacle within 8 km (4.3 NM) of the estimated position, or 2000 ft over high terrain or mountainous areas where the authority says so. The terrain here is a coarse elevation model without obstacles, so use it to see the shape of the route, not to set your minimum altitude. Your charts and the AIP decide.
Save the fixes you need (IFR waypoints, VRPs, your own points). They are stored on your profile and can be used in the route by name.

How to read the profile
Terrain shows only the ground under the route. Altitude line adds one level you choose. Climb and descent adds an illustrative path from your climb and descent gradients. None of them is a procedure.
With Climb and descent, the first and last part of the flight (shaded) is flown on a SID, an approach or visually. The tool does not have those procedures, so it does not check terrain there, and the line is dashed. Use the chart. The areas are 10 NM by default (change it under ⚙ Advanced); if you add an approach, the approach area starts at the IAF.
Between them, en route, the line is checked against the terrain: red dots mean below the highest terrain in the corridor, orange dots mean less than your clearance (1000 or 2000 ft, set under ⚙ Advanced).
The brown area is the terrain directly under the route. The red and orange dots also look at the highest terrain within the corridor on each side, which is what the IFR minimum level is based on.
The elevation model is coarse and has no obstacles such as masts or buildings. Published altitudes always come from the AIP and the charts.
Expected departure and arrival
Built from the runway numbers: a straight climb-out and a straight-in final on the extended centreline. Not the published SID or approach.

Send to the briefing packChoose the pack and send. The profile, the weather and the navigation log go with it.
Draw the profile yourself, like a page in GoodNotes: climb, cruise, descent, hold, approach and missed approach, terrain and cloud. Tick “Draw on my route” to get the real terrain and the route points under your pencil, or use a blank sheet with your own scale.
Use “Send to briefing pack” at the top to put your drawing in the pack.
Example: a finished profile
Set the highest altitude and the distance, so the grid has the right scale.
Draw the departure: runway, climb to the first fix or the SID altitude.
Cruise level, then top of descent. A 3° descent is about 300 ft per NM.
Hold, approach and the minimum. Mark the FAF and the DA or MDA.
Missed approach as a dashed line, with the altitude.
