Fuel flow.
CFR · 2024-01-01 · US · Title 14
(a) (1) The fuel pressure, corrected for accelerations (load factors), must be within the limits specified by the engine type certificate data sheet. (2) The fuel level in the tank may not exceed that established as the unusable fuel supply for that tank under § 29.959, plus that necessary to conduct the test. (3) The fuel head between the tank and the engine must be critical with respect to rotorcraft flight attitudes. (4) The fuel flow transmitter, if installed, and the critical fuel pump (for pump-fed systems) must be installed to produce (by actual or simulated failure) the critical restriction to fuel flow to be expected from component failure. (5) Critical values of engine rotational speed, electrical power, or other sources of fuel pump motive power must be applied. (6) Critical values of fuel properties which adversely affect fuel flow are applied during demonstrations of fuel flow capability. (7) The fuel filter required by § 29.997 is blocked to the degree necessary to simulate the accumulation of fuel contamination required to activate the indicator required by § 29.1305(a)(18). (b) (c)
