The 727-200 series airplane is a streched version of the -100 airplane, with ten ft addded both fore and aft of the wing. The -200 gross weight limits were increased, ad the engine thrust ratings were increased to a higher ambient temperature. Systems improvements were incorporated to increase performance capabilities.
The later airplanes are an improved model of the earlier -200 series. The later airplanes have higher thrust engines and increased fuel capacity.
In an on going effort, Maintenance and Engineering modified many of the systems, therefore each 727 is different and can not be compared.
Autoflight: An approach progress display is installed on each pilot’s panel. Dual FD-109 flight directors are installed with controls on the forward pedestal. Autothrottles are installed.
HINT: You can enable/disable the autothrottle in general by toggling the corresponding button in the Clipboard.
Instruments: The instrument comparator/warning system comprises an annunciator light panel on each pilot’s glareshield and a comparator test switch. Dual Collins radio altimeter systems are installed.
Navigation: The transponder control is on the overhead panel. VOR-ADF switches are on the RMIs. Various GPS/NAV options are available.
You can select the available navigation options in the Clipboard.
Exterior lighting consists of navigation lights, beacon (anti-collision) lghts, landing lights, runway turnoff lights, wing illumination lights, wheel well lights and strobe lights.
All navigation lights are mounted on the wing tips. Two lights are located on the leading edge of each wing tip, (red left and green right), and one white tail light is located on each wing tip trailing edge. These lights are controlled by a switch on the pilots‘ overhead panel marked NAVIGATION, with ON, OFF and ON BAT or ON BAT/GRD ON positions. In the ON position the lights are powered by 28V ac and in the ON BAT position by 28V dc from the battery bus. Only the ON position should be used. The ON BAT position is used only during maintenance towing.
Two rotating beacon (anti-collision) lights each with two bulbs, are mounted on the upper and lower fuselage at approximately the mid-cabin position.
There are two strobe lghts on each wing tip, one facing forward and one facing rearward.
Landing lights are located in the wing leading edge near the fuselage and in the outboard leading edge flaps. Runway turnoff lights are located in the wing leading edge near the fuselage just inboard of the fixed landing lights.
A single taxi light is installed on the nose gear between the two nose wheels.
A flush mounted light forward of the wing, through the use of a prism, provies two beams of light, one shining outboard at 90 degrees tot he airplane centerline, and the other shining aft toward the wing.
Each wheel well has two lights. The lights may be turned on from the pilots‘ overhead panel or individually at their respective areas, exccept for the nose wheel well light which is controlled at the external power receptacle panel.
Lighting for the aft airstair area is controlled by an AIRSTAIR light switch located on the aft flight attendant’s passenger address system panel. The switch has three positions; OFF-ON-AUTO. In the AUTO positon, the aft airstair area lights automatically come on when the stairs are locked down.
