This gauge is written specifically for Captain Sim's B737-200 and B737-200Adv aircraft (http://www.captainsim.com/products/x737/). It will inform you of appropriate take-off speeds (V-speeds), take-off trim units, Vref landing speeds, elapsed flight time, fuel used, optimum cruise altitude, optimum ERP setting and Maximum Climb Thrust (MCT). It will also indicate when the aircraft's gross weight has been exceeded and if an incorrect flap has been set. Take-off speeds are adjusted for altitude and temperature values. Provisions have been made to allow user adjustments to Optimum Altitude, Optimum EPR and Center of Gravity values. Flight time and fuel used can be reset at any time by clicking on their respective displays.
