Information typeDescription
battery voltageDisplay current battery voltage to avoid low-battery flights
flight altitudeReal-time display of drone height above the ground
flight speedDisplay current horizontal or vertical speed
GPS signalIndicates the number of GPS satellites and positioning status
airplane modeDisplay the current flight control mode (such as self-stabilization, altitude stabilization, etc.)
