Quick answers

Which pays more, aerospace engineer or mechanical engineer?

Posted mid-bands from each occupation's own corpus: Aerospace Engineer $103k–$141k, Mechanical Engineer $60k–$109k. At the midpoint that favors the aerospace engineer by about $37k a year. Only postings that state pay are counted.

Are aerospace engineer and mechanical engineer the same job?

No — despite the similar names, their postings demand mostly different skills. Skills both sets of postings ask for: Project Management, FEA / Simulation, Prototyping.

Can a aerospace engineer become a mechanical engineer?

Skill readiness is 22 percent: that share of what mechanical engineer postings demand, a typical aerospace engineer profile already covers. Note the credential gate: pe required for sign-off roles; not for most product/manufacturing roles. Estimated transition: 12–24 mo.

Can a mechanical engineer become a aerospace engineer?

Skill readiness is 17 percent in this direction. Estimated transition: 12–24 mo.

Method: each occupation’s salary band is the posted 25th–75th percentile from its own corpus; readiness is coverage of the destination’s posting-skill weight; shared skills are read from the overlap waterfall. Pairs sharing too few skills are not scored in that direction. Refreshed with the nightly scrape.
