I have noticed that when aligning for a 30 degree intercept of an ILS cone and enabling the APPR button, the 787’s and 777-300ER tend to miss the intercept and then turn the opposite direction in order to get back in line on the localiser. This continues back and forth, sometimes until quite far down the ILS which caused me to go around. Could this be due to a sharp 30 degree intercept? (e.g. Intercept at 10-20 degrees to reduce the swaying?). The effect is similar to how the old 787 model used to sway ± 3 degrees either way of a set heading on the old autopilot flight model.
