Thank you for the correction. I'm still getting used to these terminologies aft, forward, rear. Your correct its always in front of the CP. However, it's an international practiceto always get into the pilot's view by standing at the rear of the aircraft and view it from that angle.

This practice enables us to have a standard POV. Same thing applies when viewing the engine to pinpoint the positions of various components.

@Ludwig T, you’re misunderstanding the so-called international practice. If something is closer to the nose of the aircraft, it is more forward. If it is closer to the tail of the aircraft, it is more aft. The same existed on ships well before there were aircraft.

Yes, that is very absolute and correct if your looking at it from the side of the aircraft ( your forward on the left and aft on the right)

Counterweights are not used to "maintain the centre of gravity". They are not like bags of potatoes that move back & forth along the aircraft to adjust balance. They are to change the trim forces & operational characteristics necessary for control surfaces to modify aerodynamic flows. aviation.stackexchange.com/questions/35352/…

After reading that article I've understood that the CP is used to balance the aircraft during flight so that the aircraft rotates at and has a pivotal point. The CG has the tendency to move when additional weights are added onboard the aircraft and when items are removed/and or replaced. What load masters are doing is positioning the loads correctly with regards to the moment arm in order to maintain the said CP which is documented by the manufacturer. Only when the CG is balanced well your surface controls can be able to trim the attitude of the aircraft effectively

Counterweights on flight controls are used to keep the C of G of the surface itself at or forward of the hinge axis, for flutter resistance. Up and down motion of the stabilizer can excite sympathetic motions of the elevator if the surface center of mass is behind the hinge. If the extra weight isn't a problem, overbalancing, putting the C of G FORWARD of the hinge, creates an active damping effect as inertial forces on the surface make it move against the mother surface's motion.

Forward/aft and port/starboard are not relative to POV.

@Timbo to keep things simple I have edited the post and I have explained "why aft". By Point of view I meant the object relative to what your angle of sight is. If aft or forward is irrelevant to pov then tell me is section number 21 on the fuselage located at forward or aft? Supposedly, the wing is taken as a reference point. It would be at the forward section. If I were to say the FADEC component is located at 10:30 it means(universally) I'm viewing the engine from the aft or rear of the aircraft. I said aft because I was looking at wing from TE. I hope this settles it.

@Ludwig T, typically locations along the longitudinal axis are referred to by fuselage station. This normally begins at a reference point at the nose (or in front of it) and increases in number as you move toward the tail. My point is that ‘forward’ and ‘aft’ are relative to the aircraft nose, not the POV of a human observer. Something is “aft” of something else if it is further away from the nose of the aircraft. Likewise, port and starboard are relative to the aircraft’s centerline when facing toward the nose. For an engine, I agree that the clock reference is from the aft position.

@Timbo, you have been correct all this time but you failed to realise that this thing we've talking about, the location of the CG wether its aft or forward of CP depends on where the observer is looking from. Its okay to always go by what's acceptable and what's not. However, sometimes its good to challenge what's regarded as normal way of explaining by adapting to different situations such as what if I stand at the TE and explain this thing and not by viewing it from the wing tips. Since I still have my chords midpoint as my reference. It was nice having this discussion though.

@LudwigT There's no invisible separator running through an aircraft such that a point an inch in front of it is objectively "forward" and a point an inch behind of it is objectively "aft". If something isn't located fairly close to the front or back tip, you wouldn't call it "forward" or "aft" except explicitly with respect to something else.

Aft is aft and forward is forward. It doesn't matter where the observer is. By your logic the nose becomes the tail depending on which direction you are looking. Spoiler alert: it doesn't. Downvoted till this is corrected.

@LudwigT, I think what everyone is trying to tell you is that you are wrong. There is a standard for describing location on an aircraft and you are not using it. The location of the CG relative to the CP does NOT depend on the observer’s point of view. It is relative to the location along the longitudinal axis of the aircraft, always. Your description is idiosyncratic.

@Timbo duly noted. I should had not mentioned CG at the first place as it deserves a thorough understanding and or a topic of its own. I now understand your point and I'm glad everyone had brought it to my attention "the standard way" of explaining such a thing. You're all amazing!

@LudwigT Thank you for the kind words.

Downvoted for stating that DU is dangerously radioactive, which is not correct. Like most metals, it is toxic, which is a far greater issue.
