TonyPynes Posted August 17, 2011 Report Posted August 17, 2011 Do you know what your fuel flow is during climb? Quote
Skybrd Posted August 17, 2011 Report Posted August 17, 2011 My shaden fuel flow indicator indicates about 17 gph right after TO with full throttle and mixture full rich from BFL airport (about 500msl). It's a thirsty engine. I'm glad it lowers in cruise. Quote
Shadrach Posted August 17, 2011 Report Posted August 17, 2011 It's temp and DA dependent... The Bendix RSA fuel servo will adjust flow based on mass airflow through the impact tubes in the intake. At SL on a standard day a Lycoming IO360 should be flowing at ~19GPH Quote

TonyPynes Posted August 17, 2011 Author Report Posted August 17, 2011 I will contribute my new to me M20F fuel flow when I pick it up next weekend. Quote
timpercarpio Posted August 17, 2011 Report Posted August 17, 2011 Our JPI 700 indicates 18.5GPH during climb. Quote
jetdriven Posted August 17, 2011 Report Posted August 17, 2011 Ours depends on DA (temp mostly at sea level) but 18.0 GPH is average for 1,000' altitude full throttle and 2700 RPM full rich. As Ross said, the RSA-5 injector varies fuel flow based on mass air volume. Quote
fantom Posted August 18, 2011 Report Posted August 18, 2011 I'm at 18.5 to 19 GPH at SL on takeoff....DA usually 1,000 to 1,500. Quote
Lood Posted August 18, 2011 Report Posted August 18, 2011 I haven't flown down at the coast for quite some time, but at my home field, my F is very happy at 15 - 16 gal. DA is normally in the 5k ft plus region. Quote
KLRDMD Posted August 18, 2011 Report Posted August 18, 2011 At around 5,000 ft I would engage the turbo in my F model and fly 25 squared to whatever altitude I chose. I would set the fuel flow at 17.5 GPH. That was about 150º ROP. Now, in the Colemill Baron, fuel flow for initial climb at rotation (2850 RPM, WOT, full rich, 300 HP per side) is 60 GPH. At pattern altitude I bring it back to 2700 RPM (it only takes about 20 second to get to pattern altitude at 3,000 FPM initial climb at 120 KIAS - blue line +20 kts) and pull the fuel flow back to 29.5 GPH for a LOP climb that still greatly exceeds 1,000 FPM.

jetdriven Posted August 18, 2011 Report Posted August 18, 2011 Thats just a little more FF than a Bravo, and what was that useful load? 2,000 LB? Quote
