So, I'm trying to understand the specific range calculation on my Sporty's E6B electronic calculator. The manual gives two examples.
In one, the assumption is 150 Ground Speed, 24 Gallons of fuel per hour and 140 gallons of fuel on board. It also assumes 12000 MSL. The answer is 875 miles.
Then there is another example: 160 GS, 27 G/Hr, 140 gallons on board, and MSL is 8000. The range changes to 855.6.
The problem is: the altitude is not an enterable variable (those others are). Entering it and adjusting in different parts of the calculator does nothing. Does anyone know how to isolate MSL as variable in this device?
