What Happens When a Plane Engine Can’t Start?

Airplanes frequently run into issues when they are on the tarmac, which might scare passengers but they can be a good thing. Consider that a portable power supply jumpstarting the engine now means that the craft will function while in the air. Once the turbine is going, it powers itself through the winds that sift through the turbine and spin the blades. So if an airplane engine won’t start on the tarmac, there are a few steps crews will take to fix this problem.

Power the Engine

Every aircraft needs a jumpstart to get the engines running, and larger craft (like airbuses), will require power to keep vital systems functioning. This includes lighting and airflow. According to Start Pac, the size of an aircraft plays a role in how much power is required to jump start a plane.

Smaller aircraft, like private planes, can usually get away with using a 24 volt power supply. These are often portable, and usually fit into the bed of a truck. They are extremely sensitive to voltage, and failure to match proper voltage to the power unit can leave the battery without a full charge.

A larger craft will have a 24 volt battery inside of it, and that requires a 28 volt battery pack to recharge it. If the user utilizes a 24 volt pack thinking the voltage matches, the battery won’t remain fully charged for very long. That can effect in-flight systems and the battery itself.

When engines can’t start, maintenance crews have to examine the issue carefully. That’s why delays can take so long. Typically, the solution is as simple as figuring out a way to start a plane’s turbines but improper maintenance of the battery can have lasting effects.
