Description
One of 12 F-16C and 2 F-16D Aggressors deployed to Osan AB and Kunsan AB for Max Thunder 2010. Shown here is 86-0314, a former Kunsan AB bird.ΒRelated content

Typical among Aggressor units.

I knew you would have that shot of this former Kunsan bird.

Glad you liked the tie in shot and tanks for the fav!

Did you work on this aircraft before?

I was a Quality Assurance maintenance inspector when I was assigned to the 8th FW.Β I really did not "work' on the acft, but I have performed inspections of some kind after maintenance was completed. I know that I performed a weighing of this acft when I was assigned to the 'kun.
All F-16s must be re-weighed and the CG computed every three years.Β The year I was assigned to the 8th FW, all of the jets came due for their scheduled re-weigh

Performed weight and balance computations. The acft are weighed by either load cells in tripod jacks (at the acft hardpoints) or by roll-on scales at the wheels. The acft is level laterally and longitudinally, and the weights are recorded. Using some math, you take the reaction points of the fuselage stations where the weight was recorded (jackpoints or the center of the wheels) to determin the acft CG in inches relative to the acft datum as well as the Mean Aerodynamic Chord of the wing.
This ensures that no modifications or weight acquired by 'old age" puts the acft out of the CG envelope for the required missions.
You also must compute the weight and moment changes that occur as fuel is burned and munitions and external stores are released to ensure the acft will be controllable in all flight regimes.

Interesting.

Just remember "WAM" for computing any weight changes when adding or removing equipment from an acft.
Weight x Arm equals Moment

Applies to civil birds too?

Applies to everything. You take a weight, lets say one pound and locate it 100 inches aft of the datum line. The resultant moment is 100 inch- pounds.Β Think of moment as a torque applied to the aircraft.
On most modern aircraft the datum is positioned some distance forward of the nose. This keeps all moments as a 'positive number.Β On the Cessna single engine acft for example, the datum is generally at the front face of the firewall. Anything forward of the firewall has a negative moment.Β It sounds confusing, but it is really pretty simple.
