Performed nose low fuel flow tests for left and right side. First I rolled the main gear up onto a pair of auto ramps that were resting on top of 2 x 4s. This resulted in a 14 degree nose down attitude. Next, I used the same procedures as the nose high tests: Left side, right side, each single pump, dual pump. Biggest difference from the nose high tests was tank empty/usable fuel - once the pumps began cavitating, there was ~2 quarts of fuel in each fuel tank. Final fuel flow readings were:
Left side, nose low: 59.1 gph Right side, nose low: 55.4 gph
Nose low attitude established with a pair of modified auto ramps under main gear.
