I want to know if there are any European and US carriers who do it. If so are their any conditions when to do and when not to do. Opinions with reasoning are welcome.
Thanks
Hi vilas,
European flag carrier. We used to have a stable approach criteria being not exceeding 1200 ft/min below 1000 ft AAL but that was eventually changed a few years back to the aircraft established on the vertical path with no specific RoD, hence the above combination would be possible, RoD wise.
We do not have set limitations for flaps config selection for CAT A and B aerodromes ; basically you choose whatever makes sense trying to save fuel as much as possible.
With the above scenario, unless it would be a CAT C aerodrome with specific instructions, I guess 90% + of the crew would elect CONF FULL, especially in hot weather.
