2.3 SYSTEM ORIENTATION
a.
Location references used in this text are shown in Figure 2.3.
Similar components located on a common diameter around the fan are numbered
clockwise starting from the 12 o'clock position. The 12 o'clock position
is the forward point of the fan in relation to the nose of the aircraft;
this point remains 12 o'clock regardless of the direction of fan rotation.
The direction of fan may be either right (clockwise) or left (counter-
clockwise) when viewing the rotor from the top looking down. The symbol L
(left) or R (right) after the fan assembly serial number identifies the
direction of rotation.
References to the forward end of the lift fan pertain
to the inlet or top side; references to the aft end of the lift fan pertain
to the exit or bottom side.
