A320 normal ops queries
Hi 320 pilots. A small confirmation. The green yaw command bar(yaw bar) on pfd during take off and rollout phase, guides the acrft along rwy centreline. Supposing we have ils for rwy 27 but 09 doesnt have ils, and we use 09 for take off.Normally if 27 was dep rwy, fmgs would have autotuned ils 27 and usual indications by yaw bar.
But if we manually input that for a 09 takeoff, will the yaw bar appear with RWY on FMA??and if it does,will there be reverse sensing??
2. Next query is about tropopause entry in init a. The fcom pro sup 22-20 states
To minimize the effect of temperature model error in the FMS computation of the Recommended Maximum Altitude (REC MAX ALT), the ECON CRZ Mach Number, and the ETA parameters: 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
Thus if we have a tropopause of 45000 say...would you or would you modify the default?? Would you go by this proc?
