Configurations that will cause gear horn warning?

Scenario 1: extending flap without gear
- flap lever greater than 8.5 degrees
- either engine torque less than 50%
- both power levers less than detent rating

Scenario 2: flying too low and slow without gear
- both power levers less than flight idle+12 degrees
- less than 156 kts
- RA less than 1053 ft

Scenario 3 - one engine INOP approach
- one power lever less than flight idle +12 degrees
- both power levers less than rating detent
-IAS less than 156 kts
- RA less than 1053 ft
