Hello dutchman,
Glad you enjoy the bus!
Lego is correct, only V1 is called by the system. If you don't mind hearing my voice, I could add other callouts
The V1 callout was added later as an option by Airbus, and I decided to include it for convenience.
I do not know why too low flaps was called, I didn't experience this. If it happens again, please open an issue here with reproducible instructions so I can try to track it down
Like the real bus, for an aborted landing, just select another mode. For example, you can pull HDG knob to hold current heading, and then pull ALT knob to OP CLB back to go around altitude (should be set in FCU after glideslope capture). Another options is to set power to TOGA. The bus will automatically engage HDG and SRS up to FCU altitude.
Kind Regards,
Josh
