Performance
• Airspeed indicator works off of dynamic pressure of incoming air
• As air is thinner at higher altitudes, introducing inaccuracy
• Add 2% for every 1000 ft above sea level to determine true airspeed from indicated airspeed– e.g. at 5500 ft, TAS is 11% higher than IAS
Indicated vs. True Airspeed

Plan Route
• Determine Route
• Determine True Course
• Determine Magnetic Heading
• Add Course Correction for Winds
– Surface Winds are reported as Magnetic
– Winds Aloft are reported as True
– MFSF treats all winds as Magnetic
