If the aircraft CG is located at 27.3% of MAC, the LEMAC is at station 1022, and the TEMAC is at station 1198, at what station is the CG?

To find the station of the Center of Gravity (CG) given that it is located at 27.3% of the Mean Aerodynamic Chord (MAC), you first need to determine the length of the MAC in terms of the stations provided.

The Mean Aerodynamic Chord (MAC) extends from the Leading Edge Mean Aerodynamic Chord (LEMAC) to the Trailing Edge Mean Aerodynamic Chord (TEMAC). In this case, the LEMAC is at station 1022 and the TEMAC is at station 1198.

First, calculate the total length of the MAC:

• Start Station (LEMAC): 1022

• End Station (TEMAC): 1198

• Length of MAC = 1198 - 1022 = 176 stations.

Now that we have the length of the MAC, we can calculate where the CG is located in terms of stations. Since the CG is at 27.3% of the MAC:

• 27.3% of 176 stations = 0.273 * 176 ≈ 48.048 stations.

To find the actual station of the CG, you add this distance to the LEMAC station:

• Station of CG =
