uncountable
examples: The data was examined with respect to oil pressure. This showed that both the left and right engines' oil pressure generally follow each other until the start of the final acceleration, which resulted in first the right and then the left engines rolling back. The left engine oil pressure rose, as expected, as the engine accelerated: the right engine pressure, however, started to decrease, even though the engine was also accelerating prior to its rollback. Whilst, this observation, on the right engine, was based on only a few data points, it can be inferred that this was due to an oil temperature increase at, or close to, the start of the final acceleration. However, the loss of QAR data so close to the left engine rollback meant that it was not possible to draw a similar conclusion for the left engine.
gloss: To return to the previous state.

examples: The first test involved placing the restriction immediately upstream of the FOHE. As it was known that the engine would almost certainly rollback during the first acceleration attempt, only the fourth accident acceleration was attempted: the rollback occurred as predicted. Testing was also conducted with the restriction at the LP pump inlet, with the rollback also occurring as predicted during the fourth acceleration.
