What is the cost per hour of a Gulfstream V?
The Gulfstream G550 is a variant of the Gulfstream V.

From aopa.org (November 16, 2015) for the G550, it costs $4,731.05 per hour, give or take. (Assuming the plane is paid for already.)

Adjusted for inflation that's $4,825.11.

Note that the GV is older than the G550, and would generally cost more to operate.


  This figure includes fuel, maintenance (parts and labor), engine reserves, auxiliary power units if applicable, and miscellaneous expenses to include crew travel, catering and cabin supplies, landing and parking fees—all boiled down to a single number.
