By Federal Aviation Administration (FAA)/Aviation Supplies & Academics (ASA)

Weight and stability is a vital point to the security of flight. An obese plane, or one whose heart of gravity is open air the allowable limits, is inefficient and unsafe to fly. The accountability for correct weight and stability keep watch over starts with the engineers and architects, and extends to the pilot and mechanic who flies and continues the airplane. This Federal Aviation management (FAA) booklet addresses this safety-crucial subject and in learning this guide, pilots and Aviation upkeep Technicians (AMTs) will achieve the mandatory wisdom with regards to airplane weight and stability, in coaching for the FAA wisdom examination in addition to secure flight and upkeep operations.

Basic airplane weight and stability keep an eye on ideas and strategies for the instruction, and the particular weighing of an airplane commence the dialogue, together with the tools of picking out the positioning of the empty weight heart of gravity. Loading computations with loading graphs and tables of weight and second indexes stick to, together with directions on opting for the burden and middle of gravity alterations because of maintenance and adjustments or elimination and install of kit. Chapters are devoted to light-sport airplane, single-engine airplane, multi-engine airplane, and commuter and big plane, in addition to helicopter weight and stability keep watch over and picking lateral CG. additionally incorporated are examples of fixing weight and stability difficulties utilizing a hand held digital calculator, E6-B flight computing device, and a devoted digital flight computer.

This 2016 version displays the newest aviation methods, apparatus, strategies, rules, and is a key reference within the FAA Airman Certification criteria (ACS). Illustrated all through with distinctive, full-color drawings, and incorporates a thesaurus and index.

It is the responsibility of the aircraft mechanic or repairman doing the work to accurately document the weight change and record it in both the maintenance records and the POH/AFM.

To determine that the airplane is properly loaded for this flight, use the CG limits envelope in Figure 4-5 (which is typical of those found in the POH/AFM). 54 inches, and one horizontally to the right from the loaded weight of 3,027 pounds. These lines cross inside the envelope, which shows the airplane is properly loaded for takeoff, but 77 pounds overweight for landing. Figure 4-5. Center of gravity limits chart from a typical POH. indd 2 3/14/07 10:26:33 PM Loading Graph Method Everything possible is done to make flying safe, and one expedient method is the use of charts and graphs from the POH/AFM to simplify and speed up the preflight weight and balance computation.

The datum is located at the firewall. Determine the CG by adding the weight and moment of each weighing point to determine the total weight and total moment. Then divide the total moment by the total weight to determine the CG relative to the datum. The location of the CG may be expressed in terms of inches from a datum specified by the aircraft manufacturer, or as a percentage of the MAC. The location of the leading edge of the MAC, the leading edge mean aerodynamic cord (LEMAC), is a specified number of inches from the datum.
