Look at Bulhmann (swiss physician) tables.
in the attached file, numbers are in metric, but you know how to convert in imperial
as for other tables, you have an "exit letter" -> residual group.
the interesting table is the last "passage d'un col et vol sans cabine pressurisée" -> "mountain pass and not pressurized plane"
1. no climbing during the first hour
2. after this first hour, climb regularly
3. you have to do all the calculated time to get at the height
assuming you have a 7500 ft mountain, a residual group of E and a end dive time at 1:00 pm
wait until 2:00 pm (you have to shower, load the car, drink some water, speak with friends...)
you can be at this 7500 fr mountain pass at 3:00 pm, regularly
for a 12 000 ft moutain pass
wait until 2:00 pm (1 hour)
7 500 ft at 3:00 pm (1 hour)
9 000 ft at 4:00 pm (1 hour)
10 500 ft at 5:00 pm (1 hour)
12 000 ft at 6:30 pm (1 hour and 30 min)
your 4500 ft mountain is not in the table :cool2:
