Final answer:
The L/R TK PUMPS operate when there is a demand for fuel from the left or right tanks in an aircraft.It is important to ensure that the correct pumps are operating to maintain a balanced fuel flow and prevent fuel starvation or imbalance.
Step-by-step explanation:
FUEL PANEL:When does the L/R TK PUMPS 1(2) operate?
The L/R TK PUMPS typically operate when there is a demand for fuel from the left or right tanks in an aircraft.
They are responsible for supplying fuel to the engines from these specific tanks.
For example, if the left engine is running and there is fuel available in the left tank, the L TK PUMP will operate to supply fuel to the engine.
When a pump operates, it creates pressure to push the fuel towards the engine.
The fuel is then combined with air and ignited in the engine's combustion chambers to generate power.
It is important to ensure that the correct pumps are operating to maintain a balanced fuel flow and prevent fuel starvation or imbalance.
