Abstract: This device for displaying information relative to a flight configuration of the aircraft provided with at least one propulsion system, able to generate a thrust force on said aircraft comprised in a thrust range, said information comprising information relative to an energy variation of the aircraft, is characterized in that the energy variation of the aircraft is expressed by a size representative of this energy variation and homogenous at a gradient of the aircraft, and in that said device is capable of representing a range of energy variations that can be achieved by said aircraft and a current energy variation of said aircraft. Corresponding method and system for displaying an energy variation.

Abstract: A system and method of facilitating the sale of an item is disclosed. A master account that is accessible to a vendor of the item is established. The master account is established upon receiving a request to open the master account from the vendor of the item. A customer account that is accessible to a customer who purchases the item can also be established. The customer account can be established upon receiving a request to open the customer account from the vendor of the item. Funds from a purchase rebate on the sale of the item are received and are deposited into the master account. A portion of the funds is periodically transferred to the customer account.
