Pressurization; Introduction - BOMBARDIER Challenger 601-3A CL-600-2B16 Pilot Training Manual

INTRODUCTION

This chapter deals with the pressurization system of the Canadair Challenger CL-600-
2B16, model CL-601-3A. Chapter 11 described the controlled inflow of air to the oc-
cupied areas of the airplane and the conditioning of that air supply to achieve and
maintain the desired temperatures. Pressurization, on the other hand, is achieved by con-
trolling the outflow of the conditioned air to the atmosphere, but at a rate that will
achieve and maintain selected or preprogrammed cabin altitudes throughout the com-
plete operating envelope of the airplane. Pressurization also ensures complete changes
of air volume at regular intervals, adding greatly to passenger comfort.
GENERAL
The fuselage of the Canadair Challenger is
sealed from the bulkhead at the forward side
of the cockpit to the bulkhead at the aft side
of the toilet-baggage area. These are called the
forward and aft pressure bulkheads, respec-
tively. The entire structure below the floor is
also sealed, as the underfloor area (with the
CL-600-2B16 PILOT TRAINING MANUAL
exception of the center wing section) is also
pressurized. Bulkheads are provided in the
underfloor area to contain pressurization. A
state-of-the-art pressurization system is in-
stalled. This system operates on a prepro-
grammed schedule controlled by a digital
microprocessor.
Positive cabin pressure differential is auto-
matically limited to a normal maximum value
