The
purchased aircraft will need modifications to convert it into an
aircraft that will be able to be fitted with instrumentation used for
atmospheric research.
All
original passenger seats (unless they have four or five point
harnesses installed) shall be removed from the cabin. All overhead
bins shall be removed except for the four bin spaces in the aft most
section and the two bins in the forward most section of the aircraft.
Quick connections for oxygen masks shall be installed. The cabin
shall have a minimum of five and maximum of seven seats installed.
An
atmospheric research aircraft rarely operates at designed cruising
altitude and speed. The aircraft will routinely operate at altitudes
between 1,000 feet to 5,000 ft above ground level. The aircraft will
nominally operate at indicated air speeds of 180-190 knots with
engines at 50 percent power. Ambient temperatures at these altitudes
can often exceed 90 Fahrenheit.
The
contractor shall design and install a cooling system that can keep
the cabin temperature at or below 75F. The occupancy of the aircraft
is a total of two pilots and seven operators. This requirement is
both on the ground during taxi and in the air.
