We noted, "The NTSB's probable cause finding combines the G-loading
effects of those maneuvers with the atmospheric conditions forecast to exist and concludes the aircraft encountered a wind gust that combined with the G-loading
to impose on the airframe loads in excess of its design.
None of this is rocket science, but we came away with a much better understanding of the fundamental importance of angle of attack, as well as the effects of G-loading
, roll-yaw coupling and negative roll damping.
The extra weight will result in a greater occurrence of neck injuries under g-loading
When we fly the airplane within its operating envelope--a combination of speed, G-loading
and AoA--stalls are not a problem.
In other words, the wing will automatically shed G-loading
before it incurs G-induced damage.
From them, we also can learn how the airplane will perform when we need everything it has, and how we'll perform under g-loading
Abruptly pitching the nose down may result in excessive negative G-loading
and airspeeds exceeding the aircraft's velocity-load (V-G) diagram.
and weight-hauling requirements specified by manufacturers in the type certificate data sheet keep an aircraft inside a conservatively bounded envelope, ensuring the aircraft parts all remain in close formation while flying under expected certified conditions.
From it, we can determine the g-loading
the represented airplane will experience when accelerated beyond 1G at various airspeeds.
Yes, an exception is the Lazy 8, but the G-loading
applied in a well-executed example shouldn't approach 2 G, much less the airframe's load limit.
For reference, the chart on the opposite page describes the relationships between bank angle, g-loading
and stall speed.
For example, adding more horsepower to an airframe often comes with a corresponding gross weight increase because it improves climb performance on a robust airframe that likely skated past the G-loading
and drop tests.
