Jump Start
Jump Start
In aircraft, "jump starting" or "battery boosting" refers to using an external power source, like a jump starter or ground power unit, to start the aircraft's engines when the onboard battery is discharged or unable to provide sufficient power.
Why it's needed
Aircraft batteries, like those in cars, can discharge due to various reasons, such as leaving lights on, prolonged use of electrical systems, or a faulty charging system.
How it works
Jump starters or ground power units provide a temporary external power source to the aircraft's electrical system, allowing the starter motor to engage and start the engines.
Safety considerations
It's crucial to use the correct voltage and polarity for the aircraft's electrical system when jump starting to avoid damage.
Types of jump starters
Aircraft jump starters come in various forms, including portable units (like the Rescue 1220 Aero) and larger, trolley-mounted units (START PAC) designed for heavier aircraft.
Alternative Methods
Some aircraft use auxiliary power units (APUs), which are small jet engines that can start the main engines.
External Power Plugs
Many aircraft have external power plugs for jump starting and for maintenance purposes, as well as recharging the battery.
Importance of Maintenance
Regular maintenance and proper charging of the aircraft battery are essential to prevent the need for jump starts.
Not for all aircraft
Not all aircraft rely solely on batteries for starting power, and some require specialized ground power units or air blower units.
