I have two on a Ti85 which I once bought for 1 Euro and which I keep in a side pocket near the seat which I occupy at work.

"F" (the Ti85 only allows single characters as program names) calculates the amount of fuel that I have to ask the refueller for in different units (l, kg, gallons).

"D" calculates the difference of the outside air temperature from the standard atmosphere. Our on-board equipment is not showing this but it is useful for explaining why the aeroplane goes faster/slower and uses less/more fuel than expected.
