The single largest panel on the flight engineering station of the Lockheed L-1011 is the panel that deals with bleed air, pressurization and vehicle climate control. You can see the actual location of the panel in the last image of this posting. The panel, however, is in fact a collection of 4 major systems, these systems are:
- ENGINE BLEED AIR CONTROL
- CABIN TEMPERATURE CONTROL
- CABIN PRESSURE CONTROL
- ESC MONITOR
I will discuss each of the sub-panels with you over the next four postings. Today, let me give you the highlights of the various systems:
BLEED AIR
The left hand side of the large panel is home to the Engine Bleed Control (top portion), the Pack Flow Control (middle section) and the Cabin Temperature Control (lower section)
CABIN TEMPERATURE CONTROL
The 3 systems fit together, because they are all driven by engine bleed air an the system logically flows from the top of the panel to the bottom of the panel. Engine bleed air drives the air conditioning packs which result in cabin heating (temperature control).The right hand side of the large panel is home of the Cabin Pressure Control with pressure and warning instrumentation on top (the altimeter the goes into the large empty spot will come later) and the pressurization automation system below.
CABIN PRESSURE CONTROL
The bottom right section of the large panel is come to the Environmental Control System Monitor. Just like the power measurement section of the Electrical panel on the L-1011, the ECS C Monitor panel allows the second officer to monitor heating and air flow of the ECS system.
