Instead, the speed for most economical operation (ECON) is adjusted for wind and the cost index (CI), which is the ratio of time cost to fuel cost. [8] A higher cost index results in a higher ECON speed. Cost index can be given in "Boeing" or "English" units as ($/hr)/(cents/lb), equivalent to 100 lb/hr. [10] [11] A typical cost index in these ...
The procurement cost (often referred to for military aircraft as the weapons system cost) is the total price of the aircraft. A good way of looking at the difference is that the flyaway cost is the cost of making the aircraft, while the procurement cost is the cost of buying the aircraft. Procurement costs may include ancillary equipment costs ...

Drag curve. The drag curve or drag polar is the relationship between the drag on an aircraft and other variables, such as lift, the coefficient of lift, angle-of-attack or speed. It may be described by an equation or displayed as a graph (sometimes called a "polar plot"). [1] Drag may be expressed as actual drag or the coefficient of drag.

FMS (Flight Management System) Honeywell on Boeing 767–300 A flight management system (FMS) is a fundamental component of a modern airliner's avionics.An FMS is a specialized computer system that automates a wide variety of in-flight tasks, reducing the workload on the flight crew to the point that modern civilian aircraft no longer carry flight engineers or navigators.
Lift and drag are the two components of the total aerodynamic force acting on an aerofoil or aircraft. In aerodynamics, the lift-to-drag ratio (or L/D ratio) is the lift generated by an aerodynamic body such as an aerofoil or aircraft, divided by the aerodynamic drag caused by moving through air. It describes the aerodynamic efficiency under ...

It involves two safety-critical aspects: fuel calculation, to ensure that the aircraft can safely reach the destination, and compliance with air ...
