Hi EIU,
Q1 :
I have never tried to hard tune an ILS frequency for the opposite runway on takeoff as I do not really see the point of doing so.
Anyway from the FCOM
The RWY engagement conditions are:
‐ The conditions required for SRS mode engagement:
• V2 is inserted in the MCDU PERF TAKEOFF page
• Slats are extended
• The aircraft has been on ground for at least 30 s.
‐ The aircraft is receiving a LOC signal and LOC deviation is less than 1/2 dot
‐ The aircraft heading is within 20 ° of the ILS related course
‐ The ILS course is identical to the runway heading of the origin airport as selected for the active
flight plan, if any.
According to the last 2 conditions you will not get any indications, even if you try.
Q2 :
The procedure is applicable to the FMGS II Thales, therefore other FMGS versions are not concerned
During the flight plan initialization or during flight, DO NOT MODIFY the default troppause value
(36 090 ft) displayed on the INIT page or the FUEL PRED page of the MCDU
ENTER the temperature on the CRZ WIND pages at the expected CRZ FL
That's how we do it for the affected versions.
Cheers !
