and an associated BULK FUEL TEMP caution EICAS message will be displayed.
Engine Fuel Temperature Indications
Temperatures are sensed by a probe located on the top of each engine’s fuel filter housing.
Numerals are green above 5°C, and amber if below 5°C. An associated L (R) FUEL LO TEMP
caution EICAS message will be displayed.
Fuel Flow Indications
Fuel flow indications are displayed for each engine immediately below the N2 arcs on the EICAS
page. The normally green fuel flow indication will turn amber and display dashed lines if fuel flow
exceeds 5,000 pph (2,273 kg/h), or if the input value is invalid. Fuel flow can also be viewed
through FMS page selection.
