Damn right you are mate!!
Here are some good examples where "database questions" will not help you in any way...........
1. Please explain the Binary Phase Shift Keying architecture as employed in the US GPS system.
2. Explain why, in Europe at least, the FMS does not update its' position from GPS derived coordinates.
3. In GPS, why are six satellites required in order for Receiver Autonomous Integrity Monitoring to function?
4. Why do DME ground insallations have automatic gain control architecture installed?
5. Why is a high bypass ratio turbofan engine more efficient than a turbojet?
6. Explain the Froude formula as applied to propulsive efficiency.
7. Explain the differences in thermal efficiency between a petrol engine and a diesel engine, both at at high manifold pressures and low.
9. What is a squirrel cage motor and where/ why is it used?
10. How does a hang glider achieve longitudinal dynamic stability?
Can somebody explain how any of the above questions have even a remote connection to flying an airplane commercially?
No US flag carrier pilot would have the answers to all of the above questions; guess what? Apparently they don't need to either.
Ludicrous....
