"Gaia" is another term for the world....and I think has the connotations of sort of a "living entity. (Use the Force, Luke.)  I think the only airline it represents exists in the MSFS world.

If there is an Autothrottle/Autothrust system available, it is used during the whole flight often until the aircraft is fully established on the ILS (which must be regarded as the general standard for jet approaches). The autothrottle on the Boeings are so called "full time operation", meaning they work without A/P and F/D systems, from takeoff to landing

However, back to our example: After established, the pilot usually disconnects both the A/P and A/T and lands manually, unless the visibilty requires an autolanding. An autolanding MUST be used in conjunction with the autothrottle. Older aircrafts, such as the 707 (even the 727) and some regional jets are not equipped with thrust management, so the crew controls the speed manually obviously

But the answer to your question is YES. But I bet you'll find  a pilot or two who likes to manually fly the bird all the way up to cruiselevel.

i'm not sure but i think i've heart once that Southwest doesn't equip their 737's with A/T.
