Abstract
A method of simulating an aircraft one-engine inoperative (“OEI”) event includes operating a supplemental power unit (“SPU”) at a first SPU power level less than an SPU contingency power rating, operating a primary engine at a first primary-engine power level, reducing the primary-engine power level to less than the first primary-engine power level, and maintaining a sum of the primary-engine power level and the SPU power level at a power level substantially equal to the SPU contingency power rating.
Claims17
A method of simulating a one-engine inoperative (“OEI”) event in a multi-engine aircraft that does not employ identical engines, the method comprising:
- operating a supplemental power unit (“SPU”) at a first SPU power level less than an SPU contingency power rating, wherein the SPU contingency power rating is a power level after which the SPU must be inspected to assess a need for an overhaul of the SPU;
- operating a primary engine at a first primary-engine power level;
- simulating the OEI inoperative event by reducing the primary-engine power level to less than the first primary-engine power level;
- and
- maintaining a sum of the primary-engine power level and the SPU power level at a power level substantially equal to the SPU contingency power rating.
A system for simulating an aircraft one-engine inoperative (“OEI”) event in a multi-engine aircraft that does not employ identical engines, the system comprising:
- a supplemental power unit (“SPU”) operable at a first SPU power level less than an SPU contingency power rating, wherein the SPU contingency power rating is a power level after which the SPU must be inspected to assess a need for an overhaul of the SPU;
- a primary engine operable at a first primary-engine power level;
- a flight control system (“FCS”) that controls the SPU and the primary engine, wherein the FCS is operable to:
- simulate the OEI inoperative event by reducing the primary-engine power level to less than the first primary-engine power level;
- and
- maintain a sum of the primary-engine power level and the SPU power level at a power level substantially equal to the SPU contingency power rating.
A computer-program product comprising a non-transitory computer-usable medium having computer-readable program code embodied therein, the computer-readable program code adapted to be executed to implement a method comprising:
- operating a supplemental power unit (“SPU”) of a multi-engine aircraft that does not employ identical engines at a first SPU power level less than an SPU contingency power rating, wherein the SPU contingency power rating is a power level after which the SPU must be inspected to assess a need for an overhaul of the SPU;
- operating a primary engine of the multi-engine aircraft at a first primary-engine power level;
- simulating the OEI inoperative event by reducing the primary-engine power level to less than the first primary-engine power level;
- and
- maintaining a sum of the primary-engine power level and the SPU power level at a power level substantially equal to the SPU contingency power rating.
