Hiking time estimation for the HP-41CX

This program is by P. J. Schüngel and is used here by permission.

Overview

Estimates time needed for a hike based on adding the individual legs, each based on distance and altitude difference. The smaller of the two times is halved and the leg time weighted with a factor considering the path quality, total altitude, etc. (typically 0.9 for a good footpath to 2.0 climbing over rocks.) Storage for speed and climb rates (4 memories) can be modified to suit personal needs.

Translations for the german text lines are as follows:
05 "NEW DATA?"
11 "KM:H ASC?"
14 "KM:H DESC?"
17 "ASC M/H?"
20 "DESC M/H?"
25 "TOUR?" (will be printed if printer is connected, otherwise ignored)
28 "END: W=0"
32 "LEG FACT?"
36 "DIST/KM?"
38 "ASC/M?" (enter negative for descending here)
66 "TOTAL"

and you may want to change line 08 to the key you have to press for yes (25 is the "J" key for "JA".)
