SIM001 › Beyond the cockpit › The TX15 on the serial line
The screen of the TX15
The screen of the TX15 shows what ArduPilot reports, from the telemetry on the serial line. The lamps along the top show the flight mode and whether the plane is armed. Below them are the air data, the horizon and the data for navigation. Use the screen to check each action: when you press a button or a switch, you see the plane answer on the radio itself.
The screen shows that the plane is armed
If the radio line is serial, the game clock is off, the arm switch is off, the vehicle is disarmed and the TX15 screen arming is disarmed, put the arm switch on: SE pressed in is on, and SE out is off (with a toggle fitted in place of the button, up is on and down is off). The ARMED annunciator lights up. The second lamp on the screen of the TX15 shows ARMED, and it is amber.

How this is tested untested
Given the radio line is serial And the game clock is off And the arm switch is off And the vehicle is disarmed And the TX15 screen arming is disarmed When the arm switch is on Then the vehicle is armed And the TX15 screen arming is armed
The screen shows the flight mode
If the radio line is serial, the vehicle is armed and the arm switch is on, press the button for QLOITER on the front of the radio: button 1 is QHOVER, 2 is QLOITER, 3 is FBWA, 4 is CRUISE, 5 is AUTO and 6 is QRTL. The QLOITER button lights up. QLOITER: the first lamp on the screen of the TX15 shows this flight mode.

Given the radio line is serial And the vehicle is armed And the arm switch is on When the mode switch is QLOITER Then the autopilot mode is QLOITER And the TX15 screen mode is QLOITER
The throttle stick lifts the plane on the serial line
If the radio line is serial, the vehicle is armed, the autopilot mode is QLOITER and the plane is on the ground, move the throttle stick to the high position: all the way down is low, the middle is middle, and three quarters up is high. The plane stays at one place in the air, and the speed in the PFD is near 0. The plane leaves your hand and climbs away. The height above home is at least 15 m.

Given the radio line is serial And the vehicle is armed And the autopilot mode is QLOITER And the plane is on the ground When the throttle stick is high Then the flight is hovering And the plane is flying And the height above home is at least 15 m
The screen shows forward flight
If the radio line is serial, the vehicle is armed, the flight is hovering, the plane is flying, the height above home is at least 15 m and the throttle stick is high, push the throttle stick all the way up, pull the elevator stick back a little, and press button 3 on the front of the radio. The wing motors tilt forward and the plane speeds up. The speed in the PFD is above 11 m/s, and the plane flies forward. The FBWA button lights up. FBWA: the first lamp on the screen of the TX15 shows this flight mode.

How this is tested untested
Given the radio line is serial And the vehicle is armed And the flight is hovering And the plane is flying And the height above home is at least 15 m And the throttle stick is high When the pilot switches to forward flight Then the flight is cruising And the autopilot mode is FBWA And the TX15 screen mode is FBWA
The aileron stick banks the plane on the serial line
If the radio line is serial, the vehicle is armed, the autopilot mode is FBWA and the flight is cruising, move the aileron stick right: all the way left, in the middle, or all the way right. The horizon in the PFD is tilted, and the roll reading is more than 10° from 0.

Given the radio line is serial And the vehicle is armed And the autopilot mode is FBWA And the flight is cruising When the aileron stick is right Then the VTOL's wings are banked
The wings become level again on the serial line
If the radio line is serial, the vehicle is armed, the autopilot mode is FBWA, the aileron stick is right and the VTOL's wings are banked, move the aileron stick centred: all the way left, in the middle, or all the way right. The horizon in the PFD is flat, and the roll reading is near 0.

The screen shows the plane back in a hover
If the radio line is serial, the vehicle is armed, the autopilot mode is FBWA and the flight is cruising, centre the elevator stick, put the throttle stick in the middle, and press button 2 on the front of the radio. The plane slows down and the wing motors tilt up. The plane stays at one place in the air, and the speed in the PFD is near 0. The QLOITER button lights up. QLOITER: the first lamp on the screen of the TX15 shows this flight mode.

The screen shows the plane landed and disarmed
If the radio line is serial, the vehicle is armed and the plane is flying, press button 6 on the front of the radio. The plane flies to home, and lands there. The QRTL button lights up. The plane lands and stops on the ground. The plane touches the ground at less than 2 m/s, and the HUD of the sim does not say CRASHED. The second lamp on the screen of the TX15 shows DISARMED, and it is dark.
