How do you select the ignition system for an aircraft?

What are the 3 types of ignition systems?

There are three basic types of automotive ignition systems: distributor-based, distributor-less, and coil-on-plug (COP).

What is aircraft ignition system?

The aircraft ignition system, responsible for creating and supplying the electrical spark that ignites the fuel air mixture in the aircraft engine’s cylinders, has been a key part of aircraft engines since the very beginning. … In general, understanding how an aircraft works benefits the pilot.

What are the types of aircraft ignition system?

Ignition systems can be divided into two classifications: magneto-ignition systems or electronic Full Authority Digital Engine Control (FADEC) systems for reciprocating engines. Ignition systems can also be subclassified as either single or dual magneto-ignition systems.

Which components that switched on to the ignition system of light aircraft?

The systems consists of:

  • Magnetos.
  • Spark Plugs.
  • Ignition Switch.
  • Source of Electricity.
  • Solenoids.
  • Starter/Starter Motor.
  • Wires link the system all together.

Which type of ignition system is best?

Coil-on-Plug (Direct) Ignition System

The most sophisticated of all ignitions systems, this system places an ignition coil directly on the top of each spark plug and is ideal for modern engines. All of the ignition timing is handled by the Engine Control Unit, based on input from various sensors.

What are the 5 ignition systems?

Understanding Ignition Systems

  • Conventional Breaker-Point Ignition System. …
  • High Energy (Electronic) Ignition System. …
  • Distributor-less (Waste Spark) Ignition System. …
  • Coil-on-Plug (Direct) Ignition System. …
  • Conclusion.


What are the four main parts of an aircraft ignition system?

The basic components in the ignition system are a storage battery, an induction coil, a device to produce timed high-voltage discharges from the induction coil, a distributor, and a set of spark plugs.

How does the magneto ignition system works in aircraft?

The magneto is a self-contained generator of high voltage that provides ignition to an engine through spark plugs. A magnet—hence magneto—spins in close proximity to a coil of wire. … The two magnetos on most GA aircraft—the left and the right—each fire one of two spark plugs on each cylinder.

What are the requirements of ignition system?

It should be light, effective and reliable in service. It should have source of electrical energy. A method of producing high voltage from the source to produce a spark across the electrodes of the spark plug and yet limit the current flow to increase the life of spark plug.

How are aircraft ignition leads tested?

Depress the press-to-test push button switch on the lead tester. Observe that the indictor lamp flashes and gap fires simultaneously as long as the press-to-test switch is held in the depressed position. If the indicator lamp flashes and the gap fails to fire, the lead under test is defective and must be replaced.

What is the purpose of dual ignition?

Dual ignition promotes engine efficiency by initiating twin flame fronts, giving faster and more complete burning and thereby increasing power.

How does a gas turbine ignition system works?

Most gas turbine engines are equipped with a high-energy, capacitor-type ignition system and are air cooled by fan airflow. Fan air is ducted to the exciter box, and then flows around the igniter lead and surrounds the igniter before flowing back into the nacelle area.

What is high tension ignition system?

The single spark high-tension coil is the most modern of the old engine ignition systems. Unlike a buzz coil, it makes only one spark each time it is needed. … A high-tension coil is a transformer — the windings create a higher voltage through a secondary coil when the primary field coil circuit opens.

What is a magneto switch?

An ignition magneto, or high tension magneto, is a magneto that provides current for the ignition system of a spark-ignition engine, such as a petrol engine. It produces pulses of high voltage for the spark plugs. … It is also widely used in aviation piston engines even though an electrical supply is usually available.

What is the reason for having a low tension ignition system on some aircraft?

What is the reason for having a low-tension ignition system on some aircraft? Low-tension magnetos are used on aircraft that fly at high altitudes where there is a problem with flashover in the high-tension magneto distributor.
