Abstract
A gas turbine engine according to an exemplary aspect of the present disclosure includes, among other things, a control unit to command the gas turbine engine to perform one of a rolling takeoff procedure and an unrestricted takeoff procedure. The control unit is configured command the gas turbine engine to perform the rolling takeoff procedure when information required to determine whether the unrestricted takeoff procedure can be performed is unavailable to the control unit.
Claims18
A gas turbine engine, comprising:
- a control unit configured to command the gas turbine engine to perform one of a rolling takeoff procedure and an unrestricted takeoff procedure, wherein the control unit is configured to detect whether information required to determine whether an unrestricted takeoff procedure can be performed is available to the control unit, and wherein the control unit is configured to command the gas turbine engine to perform the rolling takeoff procedure when the information is unavailable to the control unit.
A method, comprising:
- detecting whether information required to determine whether an unrestricted takeoff procedure can be performed is available to a control unit;
- and
- initiating a rolling takeoff procedure when the information is unavailable to the control unit.
A method, comprising:
- detecting whether information required to determine whether an unrestricted takeoff procedure can be performed is available to a control unit;
- and
- initiating a rolling takeoff procedure when the information is unavailable to the control unit,
- wherein the rolling takeoff procedure comprises:
- accelerating an aircraft by running a gas turbine engine at an intermediate power for a period of time;
- and
- accelerating the aircraft by running the gas turbine engine at full power after the period of time, and
- wherein the period of time is a time to allow the aircraft to reach a predetermined ground speed.
