DH4 Hydraulics

“Would you know what to do if you performed the controls check after start and intermittently triggered a double rudder push-off caution?”

“And if the engineers check-it and pronounce it ‘fine’ would you believe them?”

This book isn’t a traditional study guide - it asks you questions. I believe that merely learning how a system works from a technical guide isn’t enough. I believe we learn when we interact with a subject - in fact most of our learning from the aircraft comes on the aircraft. So this guide is different. We hope you use it not just to learn about the systems, but as a reference and support guide on-the-line, in the SIM and for refresher. I hope you find it useful.
