(2,418nm) and the Learjet 60XR
(2,398nm). Each business jet in the
field, however, offers adequate
range to cover the US, Canada,
Mexico and Central America.
Note: For business jets, ‘four
passengers with available fuel’
represents the maximum IFR
range of the aircraft at Long-
Range Cruise with four passenger
seats occupied. NBAA IFR fuel
reserve calculation for a 200nm
alternate is assumed. The lines
depicted do not include winds
aloft or any other weather-related
obstacles.Powerplant Details
The Learjet 60/60XR is powered
by two PW305A engines, each
offering 4,679lbst. The Gulfstream
G100, meanwhile, offers a pair of
Honeywell TFE 731-40R engines,
each with 4,250lbst.Total Variable Cost
The ‘Total Variable Cost’ illustrated
in Chart C(top, right), sourced
from Conklin & de Decker, is
defined as the Cost of Fuel
Expense, Maintenance Labor
Expense, Scheduled Parts
Expense and Miscellaneous Trip
Expense. The Total Variable Cost
for the Learjet 60 computes at
$2,347 per hour, which is more
expensive than the Gulfstream
G100 at $2,222 per hour.
However, the Learjet 60XR
($2,168) shows the lowest variable
cost in this field of study.Aircraft Comparison Table
Table B(right) contains the range
of used prices (per Vref) for each
aircraft. The average speeds and
ranges are from Conklin & de
Decker, while the number of
aircraft in-operation and
percentage ‘For Sale’ and average
sold are as reported by JETNET.
The Learjet 60 has 12.3% of its
fleet ‘For Sale’ as of the end of
April 2018, and the Learjet 60XR
11.6%. The average number of
used transactions per month,
meanwhile, shows the Learjet 60
has an average of five and the
Learjet 60XR two per month,
compared to the Gulfstream G100
which averages less than one sale
per month over the past 12
months.Table B - Aircraft Comparison Table
