Stable Approach allows 25 degrees for offset approaches and 15 degrees for straight in (while allowing a little for rolling between parallel runways)
Extend track deviation longer after takeoff and earlier in the approach.
Turbulence in Flight - reduce scope of Airborne by 5 seconds to avoid on-ground mis-identification
Stable Approach uses approach determination of Glideslope and Localizer established. To use Loc, GS and LOC must both be established.
Stable Approach reduced stable heading to 12 degrees (was 15) or 20 degrees if ILS is offset (was 25)
