Subject: Bugfixes: 1) Fix the if (next) setLeadDistance bug
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=fdc1a2ba54b8436b8451aa78bdf7de31f7f28565;p=flightgear.git

Bugfixes: 1) Fix the if (next) setLeadDistance bug
             (reported by Csaba Halaszi /helijah)
          2) Decrease AI aircraft Heading error tolerance to 1% of its
             original value. This is necessary to mitigate spinning and
             makes for actual "on-runway" landings.
