# AMC Top Bar At the top of the screen, the top bar displays various items that convey information and offer additional options when clicked.

The following is a list of all icons and indicators along with their functionalities.

Icon	Name	Description
	Menu Icon	App menu (navigate to Fly, Plan, Vehicle Overview, Advanced, Controller, Photos, Analyze, User Account, Settings) Enable/disable Advanced Mode.
	High Level Status Indicator	High-level status description: Green - Ready to arm and take off. Orange - The vehicle is not ready to take off due to a known reason, displayed with the status. Red - An unknown fault is preventing takeoff. The selected vehicle is displayed. The VTOL mode is also shown: Hover for multirotor mode, and Aero for fixed-wing mode. Transition indicates the switch from Hover to Aero mode, and vice versa.
	Mode	Displays the current flight mode (VTOL Takeoff, Hold, Altitude, Position, Return, Land, Mission) Select to enable Altitude or Position mode.
	Armed/Disarmed State	Displays the armed state. The states are Armed - motors spinning, Disarmed - motors stopped. When airborne the indicator switches to Emergency Actions. LANDING will command the vehicle to transition back to Hover mode and land at its current location. SHUTDOWN will stop all motors in flight, causing the vehicle to crash.
	Link Selector	When you click on the Radio icon, you'll be given the option to switch between the Radio link and the VPN link. Click on your preferred link. The active link will be outlined in green and displayed in the Top Bar. (For the VPN link to work, the vehicle must have a sufficient LTE connection, and the GCS must be connected to the internet via a hotspot or Wi-Fi network.)
	GPS Status	Displays information about the GPS lock and count. When clicking on the icon, more information becomes available: Geolocation, HDOP, VDOP, and Course over Ground. If applicable, GPS Fusion can be disabled.
	Link Quality	The bars represent the Data Link signal strength. The more lines there are, the stronger the signal.
	Cellular Indicator	The bars represent the cellular signal strength. When selecting the icon, more information becomes available, such as Status, Signal Strength in %, Uplink rate, and Downlink rate.
	Vehicle Battery Status	The Vehicle Battery Indicator shows the remaining percentage of the vehicle's battery. When two DeltaQuad Evo batteries are in use, the system recognizes them as a single unit. The indicator changes color—green, orange, and red—marking the different stages of depletion. When clicking on the icon, more information becomes available, such as Voltage, Percentage, Accumulated Consumption, Current, Time Remaining, and Power.
	GCS Battery Status	The GCS Battery Status shows the remaining percentage of the vehicle's battery. The indicator changes color—green, orange, and red—marking the different stages of depletion.

At the bottom of AMC´s top bar, you will find a bar that represents the **remaining flight time** of the vehicle. This same bar also visualizes the **RTL** point, indicating where the vehicle will perform an autonomous **Return to Launch** due to a **Battery Failsafe**.

{% hint style="info" %} The calculation of the remaining flight time is dynamic and changes based on weather conditions, the mission area, and flight characteristics. The farther the vehicle is from its intended landing location, the sooner the autonomous **Return to Launch (RTL)** will be triggered. {% endhint %}
