Joseph Marszal noticed the sunset over the wings of the Cessna 172P at Crystal River (KCGC). Joe and his instructor, Carlos Tamayo, had flown to Crystal River to meet with Gudi Davis about Joe’s Commercial check ride. “The 172 has round gauges and a GPS,” noted Marszal. “I also had on board the Levil Technology iLevil SW and my Samsung Tab 4 running iFlyGPS for backup. On the way back we did an intersection hold and three approaches, under the hood, to minimums.”
