1. Student Pilots and Inactive Pilots:
The cover will support student pilots' and inactive pilot's efforts to practice, independent of an instructor, simple one instrument partial panel work for short periods of time.

2. Active Pilots:
While active pilots are taught to trust their instruments, active pilots know that no instrument is immune from partial or complete failure.  Placarding a non-functional instrument is required by regulations. Doing so insures that the instrument won't be relied upon during the next flight, and may remind the pilot that flying with a particular non-functional instrument would not be safe at all.  Every VFR pilot should have at least one aircraft instrument covers in his or her flight bag. An alert pilot is a safe pilot.

3. CFIs:
Every CFI knows that teaching partial panel work is a required and vital part of cockpit management. Conclusion's drawn from practicing how to operate an aircraft with covered instruments substantially increases a student pilot's understanding of each instrument's function. Experienced CFI's always have some way to cover an instrument. Our cover serves that CFI need by being inexpensive and durable.

4. Beginning IFR Students
Losing an instrument during an IFR flight is even more critical than during an VFR flight. Use of a cover  will quickly remind the pilot that an instrument can not be relied upon and probably needs repair at the earliest opportunity. Every IFR pilot should have at least two aircraft instrument covers in his or her flight bag.
