Lane A & B Checks vs Magneto Checks

[Animosity2k]

So I have a question with regard to the Lane A & B on a 2012 CTLSi. I started out learning in a 2009 CTLS and was always told to check for a 60-80 RPM drop when switching mags. I would switch to the First mag, watch for the drop, switch back to both mags and watch it rise back up. Then switch to the other mag and repeat.

I was told by a few people with the fuel injected versions I should go to the first Lane, then the second lane, back to the first lane, then back to both. Is this the same way everyone else does it? I also do not notice more than 10 RPM decrease when switching compared to the 60-80 I got on the flight schools non fuel injected CT ; is this typical?

Thanks

I would follow the checklist in the airplane flight manual. The systems are completely different, and you are checking different things.

Tom, when you say flight manual I assume you are referring to the POH?

There is  a nice video explaining the story behind some of these checks and  overall how the IS engine works:

POH, AFM, or AOI what ever they were calling it on the day your airplane was built.

Have a look at the file attached: this will help you to understand better why it's needed to slowly turn the key when doing the A/B line key...

Read this, watched the video. I see the correct process, but not what to look for in terms of say an RPM drop when switching.
