Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
77 words
In combination in an aircraft flight control system having means for processing signals (h VB ) representative of maximum vertical speed bias, the improvement comprising: feedback circuit means including delta stabilizer position sensing means responsive to a stabilizer position of an aircraft for providing a delta stabilizer position signal Δδ s , said feedback circuit means further having an operand Kh c /Δδ s for providing said signals (h VB ) representative of maximum vertical speed bias.
