Center of gravity moment envelope
Finally, we need to know what the center of gravity moment envelope of your aircraft looks like. You can modify it with the inputs below.
You can modify the profiles by changing the X and Y coordinates of each corner. If your profile has fewer corners than listed below, leave the remaining options blank.

Mass & balance inputs
Calculate the mass and balance for your currently selected aircraft.
Fuel planning
Specify your desired flight time in minutes to check how much fuel you need, and whether you have sufficient fuel on board.
Tank fill level
Flight time in minutes. Automatically set to the required amount if a route is planned on the map.
How many minutes it would take you to reach your alternate at the furthest point in your journey.
Any additional emergency flight time to keep in mind.
The altitude you will be cruising at, required to calculate climb fuel consumption. If left empty, an altitude of 1.000ft is assumed.
Center of gravity moment envelope
Your zero fuel mass, take-off mass and landing mass will be displayed below. If any of these points are outside of the envelope, your aircraft is not loaded correctly for flight!
Calculated mass and moments
This table displays the mass and calculated moment for each object onboard your aircraft. The mass and moment at take off, landing and zero fuel are highlighted and displayed in the Center of gravity moment envelope.

Aerodrome information
Use the search function to find an airport with a specific ICAO identifier.
Not a valid ICAO!
No notams found for this ICAO.
You can search for any valid ICAO code or directly by name. When searching for a name, it must be an exact match (not case sensitive).
There is no route active on the map. Please draw or load a route first.
NOTAMs
This tab allows you to collect and filter through applicable NOTAMs for your route or specific airfields.
NOTAM filter settings
Change the filters below to adjust which notams will be retrieved.

Find NOTAMs
Search for NOTAMs at a specific ICAO (airport or FIR), or NOTAMs along a planned route.
Routes are planned in the 'map' section of the app.
Not a valid ICAO!
No notams found for this ICAO.
Searching along route will find any notams within 5NM of the waypoints along your route. If you waypoints are spaced far apart, some NOTAMs along the way might be missed.
There is no route active on the map. Please draw or load a route first.

NOTAM data is supplied by the Federal Aviation Authority (FAA) of the United States of America, querried from the National Airspace Sysem (NAS). Some NOTAMs may not be included if they are published recently (within an hour).
Settings
This tab allows you to change your preferences with regards to how the app functions. Some settings come with a higher performance penalty or battery usage. If the app performs poorly on your device, you can try to turn off some of these settings.
Main settings
Here you can change some functions relating mostly to the map and how it renders tiles or live traffic. Higher quality settings give a smoother, more high-detail experience, but they decrease battery life and may degrade performance on slower phones or tablets.
Increases the frequency at which your GPS position updates. Turn off if your battery is draining too quickly.
Increases the frequency at which traffic positions update. Turn off if your battery is draining too quickly.
If Track-up mode is enabled, the map will rotate so that your direction of travel is always pointing up. If disabled, the map will always be oriented with North pointing up. The map will only rotate when following your position using GPS.
Parallax allows traffic markers to be displayed in 3D based on their actual altitude. This setting may help you to better understand the altitude of traffic, but it may also cause performance issues on slower devices or cause confusion about the actual position of an aircraft.
Traffic maximum altitude
15000ft
Sets the maximum altitude at which traffic is still displayed. This setting can help reduce clutter on the map. Any aircraft flying higher than this altitude will not be shown on the map.
Change default location
The default location the app uses during startup for the various maps can be changed using the button below. Your current GPS location will be set as the default.
Default location updated.
Profile options
Options relating to your profile, like server synchronization. You can choose to automatically sync your aircraft data to the server, or opt out of this and manually sync with the server if desired. You can also recover your data from the server or copy your information to another device.
If automatic syncing is enabled, any changes you make to your aircraft profiles on this device will be saved to the server.
Data is synchronized to server.
Server and local aircraft profiles do not match.

You can reset your local aircraft profiles to default if you encounter a critical bug. This action cannot be undone! This will not affect your stored data on the server, unless you have automatic synchronization turned on.
