Airspeed 4.7 0.2 2.45 2.25

Altitude 4.5 0.5 2.5 2.0

Temperature 4.986 0.229 2.493 2.38

V- CalculationAirspeed Sensor:(4.7V + .2V)/2 = 2.45V Altitude Sensor:( 4.5V + .5V)/2 = 2.5V Temperature Sensor:(4.986V + .229V) / 2 = 2.493V

Vref CalculationAirspeed Sensor:(4.7V - .2V)/2 = 2.25V Altitude Sensor:( 4.5V - .5V)/2 = 2.0V Temperature Sensor:(4.986V -.229V) / 2 = 2.38V
