List of Navboxes

All navboxes from Menu > Settings > Navboxes & Layouts explained. The units for the navboxes depend on what units are selected in Menu > Settings > Units.

Time

Shows current time in local timezone. If this number is incorrect. Go to Android settings and change your current UTC offset or timezone.

Flight time

The duration since takeoff was detected.

Altitude

Altitude above mean sea level (AMSL), automatically corrected for the QNH offset at takeoff. On Oudie N and all iPhones this is the pressure altitude. On Android phones with barometric sensor, this is the Pressure altitude. If your Android phone doesn’t have a barometric sensor, then GPS altitude is used instead.

Altitude in ft

Same as Altitude above, but always displays the altitude in feet.

Flight level

Altitude in hundreds of feet above the standard pressure level of 1013.25 hPa. This is the altitude that is used in aviation to compare the altitude of flying objects on a common standard.

Flight level altitude is typically used at higher altitudes.

FL95 = 9500 feet above the standard pressure level
FL100 = 10.000 ft above the standard pressure level
FL180 = 18.000 ft above the standard pressure level

GPS Altitude

Altitude as seen by the GPS receiver. Do not substitute this altitude with he pressure altitude above. They are essentially different and only pressure altitude should be used in aviation.

AGL

AGL stands for Above Ground Level. It is the current height above ground. It is the difference between your current altitude and the ground altitude taken from the Digital elevation model as displayed in the “Ground” navbox (see below).

Ground

Ground elevation vertically below your current position taken from the digital elevation model.

Ground speed

Current speed relative to the ground. This value is taken from the GPS receiver.

Track

Track over ground in degrees where 360° represents moving to the North, 90° represents moving East, 180° represents moving to the South and 270° represents moving to the West.

Current L/D

Current glide ratio. This number represents the division between distance traveled and altitude lost in the last seconds or minutes. A negative glide ratio represents that you have been climbing in the last seconds or minutes.

The Current L/D value is typically used together with Required L/D (see below). If your Current L/D is higher than the Required L/D, then you will reach your goal if the Current L/D remains higher than the Required L/D for the rest of the flight.

Vario

Current rate of climb.

AVG Vario

Average climb rate achieved in the last seconds. The amount of averaging can be set in Menu > Settings > Vario. A value of 20 seconds is typically used, representing approximately one circle in a thermal.

Wind

Wind direction and speed. On Oudie N and SeeYou Navigator the wind is typically measured when flying circles or 8-turns. With an optional external Indicated Airspeed sensor, it is also updated in straight flight.

Wind Direction

Wind direction in degrees. A wind direction of 90° represents winds blowing from the East. A wind direction of 225° represents winds blowing from the South-West.

Airspace

This navbox shows distance and altitude separation from the nearest airspace. Assuming which airspace is “nearest” takes altitude and distance to the next airspace in consideration. If an Airspace is horizontally 300 meters or 1000 ft away, it is typically more important than an airspace that is 300 meters or 1000 ft above you. It will typically take longer to bust an airspace vertically than horizontally.

Target

The name of the currently selected navigation target.

To

This navbox represents the angle between the glider’s forward direction (track) and the bearing to current target. When the “To” navbox is showing 0° that means you are flying string towards your target. When you are not flying straight to the target it shows the angle at which you are flying away from the target and chevrons that show in which direction you need to turn to fly towards the target. For example “10° >>” means turn 10 degrees to the right to fly directly to the target.

Distance

The distance to currently selected navigation target.

Distance to OZ

Shortest distance to the observation zone of the currently selected target. This navbox is typically used on tasks with large turnpoint radiuses.

Arrival

Expected altitude of arrival to the currently selected target. This value represents the expected height above the target when you reach it. If you setup reserve altitude, then this altitude is subtracted from the theoretical arrival altitude for your safety.

Arrival altitude is significantly influenced by the selected glider polar, MacCready setting, ballast and bugs. Make sure you understand how these parameters affect the Arrival altitude before using this navbox to perform a marginal final glide. If Arrival altitude is showing low arrival altitude, be very conservative with it – don’t bet your life on this number. You have been warned.

Suggestion: Use Current L/D and Required L/D instead. These numbers will tell you well in advance that you are not going to reach the destination at your current glide ratio.

Required L/D

Required glide ratio to reach the selected target. This is a simple division of distance to target with your height above that target. Note that this number is independent from your currently selected glider polar, bugs and ballast. It is simply showing a division between distance and height above the target regardless of your aircraft and settings.

MacCready

Your current MacCready setting. This value influences Arrival altitude and Speed to fly navboxes. You must understand the MacCready theory to use this number effectively.

Tapping on this navbox will bring up a panel where you can change the MacCready, Bugs and Ballast settings.

Speed to fly

Theoretical Indicated airspeed you should fly to achieve the optimum cross-country speed in calm air if your next thermal will be the same strength as your currently selected MacCready value.

Note that this number is not a speed to fly director. It is just showing the optimal speed in calm air. You have to adjust your current airspeed according to current lift or sink of the airmass around you.

Task Arrival

Expected height above the finish point of the task. This navbox is similar to the “Arrival” navbox, except it is calculated for the whole task.

Task Distance

The remaining distance to fly to finish the task.

Task Required L/D

Required glide ratio to finish the task. This navbox is similar to the “Required L/D” navbox, except it is calculated for the whole task.

Task speed

Speed achieved on task until the present moment.

Speed to gate

When the opening time of the start speed gate is known, this value shows the speed you need to fly to get to the start gate at the time of opening of the gate. Before you start moving towards the start gate, this number should be big enough that you will not reach the start gate too soon.

Time to gate

Time until the start gate will open.

Time to go

While this number is positive it will show how much time you should wait before you start moving towards the start gate. If you start moving too soon, you will reach the gate before it is open.

Task remaining time

On Assigned Area Task this value will show how much time is left until the minimum time to fly the task.

Task Required Speed

On Assigned Area Task this value shows the speed at which you need to fly to the finish to complete the task at the designated task time. You typically want this number to be bigger than the speed you can realistically achieve on the final glide.

Task ETA

Estimated arrival time (ETA) for the task finish line considering the task remaining distance, altitude and MacCready value.

Task ETE

Estimated time en-route (ETE) to finish the task.

Task dTime

Task Delta Time shows whether you will finish the Assigned Area task before (negative value) or after the designated task time (positive value). You typically want to finish a few minutes or seconds over the designated task time.

Last thermal

Average climb of the last thermal measured from the beginning until the end of circling. This value shows the true average of the thermal and is often surprisingly lower than the value you are seeing on your averager :)

Altitude gain

Altitude gain since the beginning of circling. When flying straight this value shows the altitude gain in the last thermal.

Speed 60′

This navbox is showing the speed you achieved in the last hour.

Flown dist.

Flown distance is the optimized distance achieved in the flight since soaring begin. Normally, this will be the number you will see at the Online contest when you land.

Triangle

Flown distance of a triangular shape flown until your current position. This navbox’s title is changed to FAI Triangle if the shape of the flown triangle represents an FAI triangle.

Closed OLC

This value shows the distance your flight will be scored if you fly straight back to the takeoff location.

List of indicators

Compass

This widget shows the map orientation. Red arrow always points towards the North.

Note that you can tap on this widget to toggle between North up and Track up orientation of the map.

Map scale

Map scale ruler.

Flight phase

This icon switches between several icons. A standing person represents you on the ground, stationary. A propeller icon represents that you are “on tow” or running an engine. A straight arrow means you are flying straight. Chevrons to the left indicate short turn. A circular icon with an arrow represents circling state.

These states are used across the app to calculate different values such as thermal average, current L/D and many other.

Round vario

This icon shows blocks representing current vario values going circles around the center. The number in the middle is the Average vario value.

Linear vario

Same as the Round vario above, except ti is linear.

Battery

This icon shows the battery percentage of your device. Tap on this icon to display more data about battery voltage, charging and discharging rates (the latter is not available on iPhone).

GPS signal

This navbox shows red bulb when GPS is bad and green bulb when it is good. Tap on this navbox to bring up a panel with more information about the GPS state.

List of Buttons

This button opens up the main menu of the Navigator app. It can not be removed from the screen.

Layers

This button opens a panel where you can control the visibility of map layers. This button can not be removed from the screen.

Zoom in / Zoom out

These buttons zoom the map.

Auto zoom

This is a toggle button. When green light appears, Auto zoom is active. In that case it will change the map zoom in such way that the target and your current position will both be visible on the map. It will auto zoom as you get closer.

Note that Auto zoom works slightly differently in North up and Track up modes. In North up mode, the target and your position is always visible on the map. In Track up more, the target is only visible if you fly towards the target. If you fly perpendicularly or in the opposite direction, the map doesn’t zoom to fit both points on the screen.

MacCready + / –

These buttons increase and decrease MacCready value.

Pilot Event Marker

Tap this button to record a PEV message in the IGC file.
