- a) an onboard performance management computer;
b) an onboard control display unit for inputting a position remote from an aircraft into said onboard performance management computer;
c) an onboard infrared probe for determining temperature at the position remote from the aircraft and generating a remote temperature signal received by said onboard performance management computer;
d) an onboard temperature probe for determining temperature at the aircraft and generating a local temperature signal received by said onboard performance management computer;
e) an onboard weather radar for determining wind at the position remote from the aircraft and generating a remote wind signal received by said onboard performance management computer;
f) an onboard inertial navigation system for determining wind at the aircraft and generating a local wind signal received by said onboard performance management computer; and
g) onboard comparing means disposed in said onboard performance management computer for comparing said remote wind signal with said local wind signal and comparing said remote temperature signal with said local temperature signal so as to determine the position remote from the aircraft where said remote wind signal is less than said local wind signal so that an altitude can be achieved that has less head wind and is therefore more economically efficient.

Abstract
An onboard aircraft flight optimization system that includes an onboard performance management computer, a control display unit, an infrared probe, a temperature probe, a weather radar, an inertial navigation system, and comparing apparatus. The control display unit inputs a position remote from an aircraft into the performance management computer. The infrared probe determines temperature at the position remote from the aircraft and generates a remote temperature signal received by the performance management computer. The temperature probe determines temperature at the aircraft and generates a local temperature signal received by the performance management computer. The weather radar determines wind at the position remote from the aircraft and generates a remote wind signal received by the performance management computer. The inertial navigation system determines wind at the aircraft and generates a local wind signal received by the performance management computer. And, the comparing apparatus is disposed in the performance management computer and compares the remote wind signal with the local wind signal and compares the remote temperature signal with the local temperature signal so as to determine the position remote from the aircraft where the remote wind signal is less than the local wind signal so that an altitude can be achieved that has less head wind and is therefore more economically efficient.
