Diamond Aircraft DA20-C1 Practice Test

When electrical power is abnormal, the priority is to preserve power for what you need to fly and land safely. The best action is to switch to essential systems, keep an eye on the remaining indications, and plan a landing if the power cannot be restored. This reduces power drain by removing nonessential loads, helping you maintain flight instruments and critical controls while you assess the situation. If the electrical system cannot be restored after using the essential loads, land as soon as practical at a suitable airport or site.

Continuing with all nonessential systems would waste precious power, making it harder to sustain safe flight. Jumping straight to a diversion without attempting to restore power is too abrupt a step when a restoration might be possible. Cycling the master switch to reset the system can disrupt displays and configurations and is not the recommended first action.
