Hi guys

In the after start checklist it gives the correct trim setting dependant on the centre of gravity. For example...CG MAC 19. Gives a flaps 1 trim of 7.7 and a flaps 2 trim of 6.8.

My question is how to work out the centre of gravity and what does MAC mean?

Cheers

Hi Stinger.

Okay, getting technical now, MAC is the Mean Aerodynamic Chord. This applies to an individual aircrafts wing chord. This has to do with the Centre of Pressure and the chord of the wing. It is better to give a link perhaps....

This will make good bedtime reading for you....

Cheers...Ken.

Omg, i wish i hadn't asked!

So I'm guessing that most folks just make sure that the trim is set in the green zone then? 😊

Thanks for the reply

I know a real pilot of Phenom 300 here in Brazil, he said that by default (of the company he works), the trim is always 9.5
