RÉSUMÉ

The problem of designing passenger aircraft active control system algorithms that reduce extreme negative load factors under the action of a design intensity downburst is considered by taking into account aircraft elastic modes. System operation principles, algorithms, and methodologies of choosing parameters using vertical gust velocity data obtained as a result of laser atmosphere scanning ahead of aircraft flight heading are developed.
