Wing loop fault refers to the overheat/leak detection system running along pneumatic lines in the wings and belly. Fire loops on the engines is a different matter. The loops consist of an outer and inner conductor separated by a "salt", when the loop gets warm, the salt becomes conductive and makes a circuit between the inner and outer conductor. ...

In my opinion the vertical position of the center of gravity (CG) is negligible. First of all the variation will be very small. Between an airplane with lead on the bottom of the cargo and an airplane with all passengers on the upper deck the CG will not move that much. And statistically the CG will probably be somewhat around the centerline of the fuselage. ...

Leading edge faps also known as slats don't really create lift. The effect on lift coefficient is minor (less than 10% in general) but they help increase the stall angle of attack. As a summary, flaps creates lift, by increasing surface area and profil camber whereas slats postpone the stall and allow for higher AOA by reducing pressure drop around the ...
