              If and
              is fulfilled, the trip is invalid.

              If and

              is fulfilled, the trip is invalid.

              Upon the request of the manufacturer, and only for those N1 vehicles where the vehicle power-to-test-mass-ratio is less than or equal to 44 W/kg then:

              If and

              is fulfilled, the trip is invalid.

              If and

              is fulfilled, the trip is invalid.

              4.1.2. Assessment of RPA per speed bin

              If and

              is fulfilled, the trip is invalid.

              If and is fulfilled, the trip is invalid.
