8-18To calculate density altitude and true airspeed...· Place the cursor on the indicated altitude (IAlt) field.· Enter the indicated altitude from your altimeter and press ENT.· Enter your calibrated airspeed (CAS) and press ENT. If you do notknow your calibrated airspeed, use indicated airspeed instead.· Enter your current altimeter setting and press ENT.· Enter the total air temperature (TAT). The GPS 95 will display theresulting density altitude and true airspeed. (NOTE: TAT is thetemperature of the air including the heating effect caused by speed.The temperature read on a standard outside air temperature gaugefound in most piston aircraft is TAT.)The winds aloft calculation determines the direction (true) and speed of thewind. This calculation requires TAS and heading information. If you havealready calculated density altitude and TAS, the TAS value will be used forthe winds aloft calculation; otherwise you may enter the correct TAS value.To calculate winds aloft...· If you have not already calculated TAS: place the cursor over the TASfield, enter the correct true airspeed and press ENT.· Place the cursor over the heading (Hdg) field.· Enter the current heading (magnetic) from your heading indicator andpress ENT. The GPS 95 will display the wind direction, speed, and thehead/tail wind you are encountering.8.16 TRIP AND FUEL PLANNING (E6-B)The Trip and Fuel Planning Page allowsyou to calculate time and fuelrequirements between any twowaypoints or for any programmedroute. On the first cyclic field, you willchoose between waypoint (WPT) orroute (RTE) planning by highlightingand pressing CLR. If route planning isselected, you would then select the desired route number and the portion ofthe route (a given leg or all of the route) to calculate for.
