Dead Reckoning and Flight Planning
Derive the fuel plan for a 3-leg VFR cross-country using a navigation log, incorporating taxi, climb, cruise, descent, and fixed reserve.
Calculate true airspeed from IAS, pressure altitude, and temperature using the CRP-5, and verify against a second method.
Construct a dead-reckoning (DR) position after 45 minutes of flight given heading, TAS, wind, and elapsed time, using a manual plot.
Identify and correct for three common flight-planning errors: incorrect variation application, omitted wind correction, and misapplied fuel burn.
