Applying a load simultaneously, to the point where the aircraft cannot support itself.
If your unloading an aircraft, you need to be as close as possible.

Generally speaking, a conical shock wave indicates a disturbance(in this case an aircraft) in the air travelling at a speed greater than that of the sound. But this only happens under ideal conditions. Real aircraft have very complex shapes and some part of the aircraft may experience shock wave earlier than the rest (over the bubble canopy or over the wing), so you usually don't get to find a perfect conical shock wave forming around an aircraft in real life.
On a military transport aircraft it is the loading bay in the tail of the aircraft. on a passenger jet it is the cargo hatch on the rear side.
Establishments manufacturing aircraft loading hoists are classified in SIC 3537
Wing Loading is the details of the distribution of pressure on an aircraft wing. An aircraft flys by producing Lift by its wings. This lift force depends on the shape of the wing that produces high pressure on the bottom of the wing and low pressure on the top. The center of the lift is usually at the 1/4 chord or 25% of the width of the wing as measure from the leading edge. The Wing Loading can be designed to produce different Lift and ensure the aircraft will be easy to trim for level flight.
Wing cube loading is a measure used in aviation to assess the performance of an aircraft's wings in relation to its weight. It is calculated by dividing the aircraft's total weight by the volume of the wing's displacement, which is typically expressed in cubic feet or meters. This metric helps determine how efficiently an aircraft can generate lift; lower wing cube loading generally indicates better lift capabilities and maneuverability, making it especially important in the design of performance-oriented aircraft.
Aircraft line operations refers to all of the various services performed on aircraft. This includes fueling, towing, deicing, loading & unloading and other services aircraft need between flights.
The conical angle of a shock wave narrows as a supersonic aircraft gains speed. This is due to the increase in the Mach number, causing the shock wave to become more tightly packed around the aircraft.
A dynamic load arises from the acceleration or deceleration of a "static" load (mass). A shock load occurs when this acceleration or deceleration is very large and the the time frame is very short.
When considering cargo for selection on a specific airframe, you should consult the aircraft's Weight and Balance Manual, Aircraft Flight Manual, and any specific cargo loading procedures provided by the aircraft manufacturer. These publications will provide you with important information on weight limitations, cargo compartment configurations, and loading restrictions specific to the aircraft.
A faster supersonic aircraft would typically produce a narrower conical shock wave due to the leading edges of its wings and fuselage pushing air molecules quickly aside. This rapid displacement of air creates a more condensed shock wave compared to a slower supersonic aircraft.
