User Interface

Design Philosophy

We developed Air Navigation Pro in conformity with EASA and FAA EFB design recommendations. The core of our app is the Moving Map, surrounded by menus to access the features. All windows display on top of the map, allowing you to easily return to it at any time. This design ensures that critical information is always accessible without disrupting the navigation experience.

For enhanced safety, our app has two modes: Edit Mode and Flight Mode. Edit Mode is intended for the flight preparation phase, while Flight Mode is to be used during the flying phase, as it locks the route and prevents you from making unintentional changes to it during the flight.

The color scheme decisions are deliberate, with informative text always in white, while all tappable interactive elements are yellow. Red indicates caution and appears rarely, ensuring it stands out when necessary.

We focus on responsiveness and the use of intuitive finger gestures to ensure an easy, quick and natural feel with common gestures that you are already familiar with. We view our app as a supportive tool for pilots, not a prescriptive one. We believe that the pilot is always in charge and the primary decision-maker. Therefore, most of the features in our app are fully customizable, allowing users to tailor the app to their specific needs and preferences.

Route Overview

At the top, you will see the Route’s Name, Departure Time and total route distance in nautical miles (NM). Below, your route’s waypoints are listed along with key flight details.

In Edit Mode, waypoints display:

• Distance to Next Waypoint (DIST)

• Planned Altitude (PLN)

• Magnetic Heading (MH)

• Magnetic Course (MC)

• Estimated Time En Route to Next Waypoint (ETE)

• Groundspeed (GS)

In Flight Mode, waypoints display:

• Distance to Go (DTG)

• Planned Altitude (PLN)

• Bearing (BRG)

• Magnetic Heading (MH)

• Magnetic Course (MC)

Tapping on a waypoint opens a pop-up window, where you can access various actions and settings.

Waypoint Pop-up Window

In Edit Mode, you can further configure route details. See more in Route Planning. In Flight Mode, you can enter actual fuel on board and actual time over for each waypoint. This data is used in the Post Navigation log document.

Additionally, the following shortcuts are available:

replaces your current route with a direct route from your current GPS position to the selected waypoint.

simulates a HSI for the selected waypoint.

simulates a VOR for the selected waypoint.

simulates a RMI for the selected waypoint.

centers the selected waypoint on the map.

switches between Edit Mode and Flight Mode from inside the pop-up window.

sets the selected waypoint as the next destination.

removes the selected waypoint from your current route.

Instrument Display

The default Instrument is the HSI. By tapping the icon, you can access a list of available instruments to display. To hide the instrument, simply tap the icon.

Navigation Bar

The Navigation Bar provides real-time navigation data tailored to your needs. The number of fields displayed depends on your screen size. You can choose navigation values from an extensive list of options, allowing you to prioritize the information most relevant to your flight.

Customization

You can easily modify the value of any field on the Navbar to display the information you prefer. Simply long-press on the field you wish to change and a popover with a list of available options will appear. Scroll down to see more choices. Finally, tap on your desired value to select it.

Note

Some values require more space than others, so if you select larger information values to be displayed, the bar may contain fewer fields.

Additionally, the Navbar is intelligently designed to prevent duplicate information. For example, if you replace Groundspeed with Altitude but Altitude is already displayed in another field, the two values will swap places rather than Altitude appearing twice.

Navigation Values

Below is a complete list of the available navigation values, listed in alphabetical order. Some values also have additional interactive functions, indicated by a small yellow triangle symbol. Tapping on them will allow further actions.

• Acceleration: Accelaration indicated in G units

• Altitude: Altitude (MSL) as reported by the GPS or the selected pressure source in Tools > Sensors. Tap to access the QNH setup menu. QNH is used to adjust the barometer for the current atmospheric pressure. You can set it manually or allow the app to update it automatically. By default, automatic setup is enabled, updating QNH via the internet. A yellow timestamp shows the time of the last update. Tap it to manually refresh the QNH to the current time. To set QNH manually, toggle OFF the automatic setup option and select a value from the QNH selector list. You can change the QNH unit in Configuration > Settings > Units.

• Autopilot: Tap on it to adjust the autopilot mode (requires supported hardware by Levil Aviation )

• Current position: Coordinates of the current GPS location. Tap it to create a User Waypoint at your position. A pop-up will ask if you want to edit the waypoint. Select Cancel to use the default settings or Show to open the waypoint editor for customized adjustments, such as the name, altitude or tags.

• Flight time: Elapsed time since the beginning of your flight

• GPS Accuracy (H/V): Horizontal and vertical accuracy of your GPS location indicated in meters

• Groundspeed: Speed relative to the ground

• Height over ground: Height above ground level (AGL)

• Landings: Number of landings for your current flight

• Track: GPS track direction in degrees from North

• UTC Time: Current Coordinated Universal Time

• Vertical Speed: Rate of ascent or descent

If a route has been planned, the following values are also available:

• Bearing: Bearing to the next waypoint

• DEP/ARR: Selected departure and arrival procedures. Tap to open a popover with a list of take-off and landing airfield traffic patterns to choose from for your route, when available.

• Distance: Distance to the next waypoint

• ETA (dest): Estimated time of arrival (UTC) to your destination

• ETA (next): Estimated time of arrival to the next waypoint

• ETE (dest): Estimated enroute time to your destination (mm:ss)

• ETE (next): Estimated enroute time to the next waypoint (mm:ss)

• Next waypoint: Identifier and name of the next waypoint. The waypoint displayed here is used to calculate all values related to the next waypoint. While flying, the next waypoint value is automatically updated once the waypoint is reached. Tapping on it opens the list of waypoints in your route, allowing you to manually select a different waypoint. All values related to the next waypoint, such as ETA (next), Distance and Bearing, will update automatically based on the newly selected leg.

• Planned Altitude: Preferred planned altitude to the next waypoint

• XTE: Cross Track Error indicating the distance off your planned route

Mobile Version Specificities

Considering the small screen size, the mobile Navbar has been designed to adapt to your needs at each stage of your flight experience. With no route, the Navbar displays a single row, offering a larger map area for Route Planning.

Once a route is set, the Navbar automatically expands to two rows, providing more information during your flight navigation. Additionally, the two rows serve distinct purposes:

• Top Row: Customizable with fields related to your route, such as Next Waypoint, Distance or Planned Altitude.

• Bottom Row: Customizable with fields related to GPS or external sensor data, like Track, Altitude, Acceleration or Vertical Speed.

Note

Some values require more space than others, so if you select larger information values to be displayed, the row may contain fewer fields.
