Utility for pilots of the Piper Meridian, M600, M700, and JetProp DLX (-21 and -35) airplanes. Pilot enters altitude and outside air temperature; the app immediately calculates max speed cruise torque, true airspeed, pounds per hour, and NM/pound. Uses calculations from tables 5-67 through 5-73 of the performance section of the Meridian POH (circa September, 2011); figures 5-16 through 5-31 of the M600 performance section; and the JetProp Cruise Performance charts in the JetProp DLX (-21 and -35) POH. Pilot can flip through different torque settings to see the effect of torque on airspeed and fuel consumption. Pilots should use solely for educational purposes. Always refer to your current Aircraft Flight Manual (AFM) or Pilot Operating Handbook (POH) for use while operating an aircraft. Your aircraft's POH is updated regularly by the manufacturer and is the only source of torque information you should use operating an aircraft. ## Key features - Calculates max speed cruise torque - Determines true airspeed - Estimates pounds per hour fuel consumption - Calculates NM/pound fuel efficiency - References official POH data - Allows flipping through torque settings ## Recent user reviews (1 of 1) All indexed reviews: https://appshunter.io/ios/app/meridian-jetprop-torque/id1315249142/reviews.md ### 5/5 — Good stuff *2018-01-11* This is a simple but very accurate app. I’m currently flying a JetPROP DLX (-35) and find the speeds to be right on.
