About

AERO Caller

Read full description

Aero Caller is designed for aerobatic pilots, callers and judges who need a clear, reliable way to practise and assess schedules. Select a schedule, choose left or right direction, use short or long descriptions, and step through manoeuvres manually or with hands-free voice commands. Pause and resume playback, skip to the next manoeuvre, and add notes without interrupting your session. The new judging tools let you score each manoeuvre, record comments and create a detailed flight summary. Local weather conditions can also be included, giving pilots useful context when reviewing their performance. Download and edit schedules, customise descriptions, add manoeuvre images, duplicate schedules and export backups. Whether you are training at the field, calling for a pilot or judging a flight, Aero Caller keeps every manoeuvre clear and every result organised.
