I had a buddy who was recently asked on an interview to calculate a climb VSI for a climb gradient for a DP off of a jepp chart. Anyone have any idea how to do this? Any rule of thumb how to do this without the table?
I believe jepp includes a climb gradient table. I know the FAA charts have a table in the back.
Thanks.

I like using the units and
120Nautical Miles (nm) per 1 hour = 120nm/ 1hr
or 120nm / 60minutes(min) which equals 2nm / 1min
Required climb gradient for the Pitkin four out of KASE = 500ft/1nm
ft/min required = 2nm/1min * 500ft/nm
=
2nm * 500ft
------------
1min * 1nm
equals 1000ft/1min
note the nm cancel out and you're left with ft/min as your units.
Of course you're flying a part 25 aircraft and ahh screw it, if we lose one we'll just go visual down to Rifle. . .
