Did the Nazca Lines actually work as some kind of landing calendar?

Been thinking about this a lot lately and I keep coming back to the same question - why are some of the lines so incredibly long and straight when the Nazca people had no way to view them from above? Like the precision alone suggests they were working to some external reference point, not just drawing on the ground for fun.

The "landing calendar" angle is interesting but I'd push it slightly differently. What if they weren't marking where craft land but when? Certain lines aligning with solstices and specific star risings could function as a kind of astronomical clock, and if you were returning visitors you'd know exactly what the ground pattern meant in terms of timing.

Has anyone cross-referenced the geoglyph orientations with the Pleiades cycle specifically? I've seen a bit of research suggesting a connection there but nothing definitive. Also curious whether the trapezoid shapes have been properly analysed as potential clearing zones rather than just decorative forms. That bit always gets overlooked in the mainstream stuff.

Bit outside my usual area but this has always fascinated me. The straight lines thing is actually easier than people think - you can achieve surprisingly accurate long straight lines using basic stakes and rope, no aerial view needed. The real question for me is why they bothered with such precision at all. What purpose required that level of effort? That's the bit I can't get past.
