An airplane flying at an 81 degree heading at 34N latitude, has an airspeed of 456 miles per hour. The altimeter is set for a sea level pressure 1010 hPa and keeps an indicated altitude of 38,850 feet. Starting at a one-hour period, the altimeter shows 37,203 feet. At the end of the 1 hour period, the radar altimeter shows 35,300 feet. If the purely geostrophic flow is assumed, tell what direction and about how far has the aircraft drifted from its course.
