161 /*******************************************
164 Currently user is assumed to have taken off again when leaving the runway - check speed/elev for taxiing-in. (MAJOR)
166 Use track instead of heading to determine what leg of the circuit the user is flying. (MINOR)
168 Use altitude as well as position to try to determine if the user has left the circuit. (MEDIUM - other issues as well).
170 Currently HoldShortReported code assumes there will be only one plane holding for the runway at once and
171 will break when planes start queueing. (CRITICAL)
173 Report-Runway-Vacated is left as only user ATC option following a go-around. (MAJOR)
175 Report-Downwind is not added as ATC option when user takes off to fly a circuit. (MAJOR)
177 eta of USER can be calculated very wrongly in circuit if flying straight out and turn4 etc are with +ve ortho y.
178 This can then screw up circuit ordering for other planes (MEDIUM)
180 USER leaving circuit needs to be more robustly considered when intentions unknown
181 Currently only considered during climbout and breaks when user turns (MEDIUM).
183 GetPos() of the AI planes is called erratically - either too much or not enough. (MINOR)
185 GO-AROUND is instructed very late at < 12s to landing - possibly make more dependent on chance of rwy clearing before landing (FEATURE)
187 Need to make clear when TowerPlaneRecs do or don't get deleted in RemoveFromCircuitList etc. (MINOR until I misuse it - then CRITICAL!)
189 FGTower::RemoveAllUserDialogOptions() really ought to be replaced by an ATCDialog::clear_entries() function. (MINOR - efficiency).
191 At the moment planes in the lists are not guaranteed to always have a sensible ETA - it should be set as part of AddList functions, and lists should only be accessed this way. (FAIRLY MAJOR).
