Day 3 Progress Check

Question 1

What should you do if the engine does not cease firing in the off position during the ignition switch check?

Answer 1

Quickly return the switch to the both position

Question 2

What is the RPM drop parameter typically observed during an ignition system check for each magneto?

Answer 2

25-75 RPM

Question 3

At what engine speed should the ignition switch check typically be performed?

Answer 3

700 RPM

Question 4

Which method can be used to check magneto internal timing by aligning a straightedge with a step cut on the breaker cam?

Answer 4

Method 1: Model-Specific Step Method

Question 5

What is the purpose of the ignition switch check in the ignition system checks procedure?

Answer 5

To ensure all magneto ground leads are electrically grounded

Question 6

How is magneto timing checked using a timing pin and vent hole marks?

Answer 6

By aligning red marks visible through a vent hole

Question 7

What is the purpose of aligning a timing mark with a pointed chamfered tooth when checking magneto internal timing?

Answer 7

To ensure the correct E-gap angle

Question 8

Why is checking the internal timing of a magneto critical during installation or replacement?

Answer 8

To optimize the magneto’s spark strength

Question 9

What is the E-Gap angle in the context of magneto timing?

Answer 9

The angle at which breaker points begin to open

Question 10

Why should you never rotate the propeller if the engine does not cease firing in the off position during the ignition switch check?

Answer 10

Engine may fire and can result in personnel injury or death
