A study was conducted to evaluate the effectiveness of a Pictorial Navigation Display PND as a conceptual training aid for instrument flight training. The PND was capable of providing Heading-Up and North-Up information to the pilots. Results showed that the PND was generally superior to the conventional very high frequency omnirange VOR navigation instrument when used alone, and proved to be an asset to the instrument student pilot. A comparative evaluation revealed that the North-Up mode of the PND was favored over that of the Heading-Up mode. Operationally, all subject pilots were able to meet the navigation requirements of the Instrument Flight Rules IFR syllabus proficiently with the PND. There were no unusual responses with either the North-Up or the Heading-Up modes of the display. The training times and the pilots comments showed greater confidence and better accuracy when using the North-Up mode of the PND. The effectiveness of the PND as a conceptual training aid was confirmed by observing and documenting the performance of pilots flying an aircraft in simulated IFR environment without the assistance of the PND.
