Boeing 747 Weight And Balance Manual
Published 3:00 PM EST Feb 18, 2018 Question: Some aircraft have three seats on one side of the aisle and two seats on the other side. Does this imbalance affect aircraft performance? Shouldn't the weight be distributed evenly on each side of the aircraft? — Submitted by reader Matthew R, Syracuse, N.Y. Answer: The weight is balanced due to the aisle being offset a bit. Airplanes such as the DC-9, MD-80/90 and Boeing 717 have the 3–2 seating in the main cabin. They fly normally with no imbalance due to good design engineering.
[G450 Weight and Balance Manual, ¶2.1.2.5] Horizontal Arm, measured in inches. A Boeing 747, for example, could have a center of gravity 960' behind the. Aug 31, 2015 - Purpose: This InFO advises certificate holders of B-747, B-767, and B-777 aircraft that the Boeing. WBMs have been modified for certain cargo.
Q: On Allegiant Air they try to get customers to pay for picking a particular seat. Recently, while traveling with my wife on tickets booked together they seated us in different rows. They then make an announcement saying that nobody should switch seats because they use a computerized weight and balance system on the plane. I can appreciate the fact that balance is important in aircraft performance but baggage seems to get loaded in a pretty random manner with little concern for weight and balance.
Can you provide any clarification? — Joe, Springfield, Ill. A: Many airlines use computer weight and balance programs. Gep65 manual. The airplane is divided into zones and the number of passengers in each zone is entered in the program.

This allows for the balance of the airplane to be determined. It is likely that your flight was near a limit and they did not want people changing zones. Your statement about baggage being loaded randomly is not correct. The weight in each cargo compartment is calculated prior to loading.
Airlines use standard weights for bags and people, allowing them to do the calculations in advance. This speeds up the loading process significantly. Q: I was flying Akron Canton to Charlotte on United and right before we left the flight attendant needed someone to move to the back because of weight. How can 100-200 pounds make a difference and why? — Lisa Crall, Bolivar, Ohio A: In some airplanes, it can make a difference.
Before every flight, performance calculations are done to ensure that the airplane can safely take off and land. One of the calculations is the weight of the airplane, another is the balance. Balance is important for proper control (primarily pitch control) during takeoff and in flight. During certification, the manufacturer demonstrates various balance points, known as center of gravity, to the regulator (in the U.S., that is the FAA). Based on those demonstrated points, a flight envelope is developed. To maintain the proper balance, the center of gravity must be within the envelope and the airplane is loaded with passengers, cargo and fuel accordingly. In your case, it was necessary to move one person aft to move the center of gravity back and into the envelope.
Q: Why would passengers be removed unwillingly for an overweight aircraft? Aren't the paying passengers the first part of the weight and balance formula? — Neil, East Aurora, N.Y. A: The first part of the weight and balance plan is the fuel needed for the flight. Load planning agents then account for the scheduled passengers, bags and cargo.
Variations to the planned load can result in overweight conditions. A decision has to be made how the weight can be reduced; sometimes it is removing a few passengers. Removing passengers can be faster than removing an equal amount of bags.
This is a difficult decision for the ground staff to make. John Cox is a retired airline captain with US Airways and runs his own aviation safety consulting company, Safety Operating Systems.

As recognized weight and balance trainer for multiple operators with Boeing B747F, Mr. Daniel is pleased to familiarize you with the specifics of this aircraft type.
Please contact us for more information! Weight and Balance Training! Load planning with calculation of flight-related data is in principle similar for each aircraft type, whether it is a Cessna C-152 or a Boeing B747. Maximum allowable weights and limits may not be exceeded (e.g.
Positions, zones, compartments, cumulatives). All load must be distributed in a way that the center of gravity of the aircraft is within a predetermined range of the airplane flight manual. The calculation of the load plan and the load & trim sheet (weight & balance) is getting of course more and more difficult with the size of the aircraft. As recognized weight and balance trainer for multiple operators with Boeing B747F, Mr. Daniel is pleased to familiarize you with the specifics of this aircraft type.
