This Piper "Flight Computer" gives you an example of using existing products like the TI-35 for other purposes. We know similar approaches from the insurance business (view the TI-58 manufactured for Lloyd) but this one uses a specialized integrated circuit to perform different computations and conversions:

Alt/AS: Calibrated, True Airspeed, Pressure, Density Altitude
WIND: Wind Speed, Direction, Course and Heading 
TSD: Time-Speed-Distance, Distance and fuel consumption
CMP: Computes in the above modes the different values
CNV: Convert between US and SI-units
T: Time calculations

The development of this product was done by Jeppesen Sanderson, view the original product here.
