And how would you suggest implementing the speed and altitude?  Where
speed = (1.08^x)-1 and altitude = 1.002^x?  Yeah, it's easy on a PC
where you've got floating point support and memory and CPU cycles to
burn.  Not fun on an 8-bit MCU that more often than not doesn't even
have a hardware multiplier.  Certainly not as simple as the single
QBASIC statement needed to handle it might imply.
