Rule 3a
Lower RRB to increase nose lift (N), (CRB is in the high position). If there is ample tail clearance, some increase in
N can be obtained by keeping the CRB in its highest position and lowering the RRB to its lowest position. The
mathematical equation for this process is shown under Table 3-28, column (m). N Rule 3a. - N Rule 2 + Value N
calculated from the equation shown under Table 3-28, column (m).
p.
Rule 3b
Lower CRB to increase tail clearance (T), (RRB is in the high position). If there is ample nose clearance, some
increase in T can be obtained by keeping the RRB in the highest position and lowering the CRB to its lowest position. The
mathematical equation for this process is shown under Table 3-28, column (n).
T Rule 3b. - T Rule 2 + Value T calculated from the equation shown under Table 3-28, column (n).
