AP A flying a departure with No 1 VOR and No 2 VOR tuned. Intention is to fly outbound from No1, then change to No2 and track outbound on separate radial. EGLL ULTIB Departure with LON 113.60 R071 on No1 and BIG 115.10 R330 on No2. When changing to No2 the AP A will not complete the intercept. Changing radials on No1 or de-tuning the VOR will allow normal operation.
Somehow No1 data is being used for part of the intercept logic, even when No2 is in use.
Also related the right side flight directors are providing incorrect guidance in this case.
