Control system and method
First Claim
1. A system for controlling a powered unit having an engine configured to operate using a plurality of fuel types each in a corresponding fuel tank, the system comprising:
- a controller operable to;
transmit a first set of control signals including a first set of valve signals to each fuel tank based at least in part on a first stored engine operating profile to control amounts of fuel from each fuel tank to the engine;
transmit a second set of control signals including a second set of valve signals to each fuel tank based at least in part on a second stored engine operating profile to control the amounts of fuel from each fuel tank to the engine; and
switch, by transmitting either the first set of control signals or the second set of control signals, between a first operating condition associated with a first external domain and a second condition associated with a second external domain, wherein the first operating condition is associated with the first stored engine operating profile, and the second operating condition is associated with the second stored engine operating profile.

Abstract
A system is provided for controlling a powered unit having an engine configured to operate using a plurality of fuel types each in a corresponding fuel tank. The system includes a controller operable to transmit a first set of control signals including a first set of valve signals to the each fuel tank based at least in part on a first stored engine operating profile to control amounts of fuel from each fuel tank to the engine. The controller can transmit a second set of control signals including a second set of valve signals to each fuel tank based at least in part on a second stored engine operating profile to control amounts of fuel from each fuel tank to the engine. Further, the controller can switch, by transmitting either the first set of control signals or the second set of control signals, between a first operating condition associated with a first external domain and a second condition associated with a second external domain. The first operating condition is associated with the first stored engine operating profile, and the second operating condition is associated with the second stored engine operating profile.

17. A method for controlling a powered unit having an engine configured to operate on a plurality of fuel types, comprising:
-
transmitting a first set of control signals to a plurality of fuel tanks based at least in part on a first stored engine operating profile to control amounts of fuel flowing from each of the plurality of fuel tanks to the engine; transmitting a second set of control signals to a plurality of fuel tanks based at least in part on a second stored engine operating profile to control the amounts of fuel flowing from each of the plurality of fuel tanks to the engine; and switching between a first operating condition associated with a first external domain and the first stored engine operating profile and a second operating condition associated with a second external domain and the second stored engine operating profile. - View Dependent Claims (18, 19)

20. A controller for a powered unit having an engine configured to operate on a plurality of fuel types, comprising:
-
means for transmitting a first set of control signals to a plurality of fuel tanks based at least in part on a first stored engine operating profile to control amounts of fuel flowing from each of the plurality of fuel tanks to the engine; means for transmitting a second set of control signals to a plurality of fuel tanks based at least in part on a second stored engine operating profile to control amounts of fuel flowing from each of the plurality of fuel tanks to the engine; and the controller being operable to switch between a first operating condition associated with a first external domain and the first stored engine operating profile and a second operating condition associated with a second external domain and the second stored engine operating profile.
