I personally find interesting both take-off and landings on a320 (a lot of things to do in the cockpit)…so, I personally prefer short (or very short) flights to test the A320…
I often do “circles” on selected Airports to test my landing capabilities with the A32NX…here’s a couple I suggest:
San Francisco : KSFO departing runway 01R, then NIITES03 SID, GOBBS, SUTRO, then ILS 28L at KSFO (all done with the FMC)…nice passing over the San Francisco Bridge , 10 minutes flight…beatiful
an other one in Frankfurt…takeoff from runway 7R, SOBRE6E SID, then direct to ILS 7L
finally, just did it (my favourite) London lift-off from EGLC (london City) 27 to 3000 feet and immediately after take-off intercetpt Heathrow /EGLL 27R ILS…super busy but with beatiful views on London…
try them! and let me know if you have any similar with big airports and beatiful town views…
Thanks
