7.1 SAFE Technology
The Apprentice STS 1.5m features exclusive SAFE (Sensor Assisted Flight Envelope) technology, which provides multiple flight modes to assist new pilots:
- Ipò Ibere: Offers pitch and bank angle limits, automatic self-leveling, and assisted take-offs and landings. This mode is highly recommended for first flights.
- Ipo agbedemeji: Provides larger pitch and bank angle limits with self-leveling, allowing for more maneuverability while still offering stability assistance.
- Experienced Mode: Removes pitch and bank angle limits and self-leveling, providing full control for advanced maneuvers.
7.2 Take-Off
Position the aircraft into the wind on a smooth surface. Gradually increase throttle while applying slight up-elevator to lift off. The wide-stance tricycle landing gear aids in stable ground handling.
