Key: what the circles and colors mean
Each circle is a bill. The ring fills as it moves through Congress:
Under the number: the Yea · Nay count of its final (or latest) recorded vote. On a member's page, the small badge is how that member voted: Y Yea / Aye, N Nay / No, P Present, – Not voting.
Gold and violet are only for Yea and Nay; they never mean a party. A member's party is the letter on their photo.
Not yet voted on. This bill is still a proposal: it hasn't reached a floor vote, and its text can change in committee or on the floor before any vote.

Safe Air on Airplanes Act
This bill directs the Federal Aviation Administration (FAA) to update regulations to phase out and prohibit bleed air systems in certain types of aircraft. In general, a bleed air system uses compressed air that is taken from an aircraft engine that is upstream of the combustion chamber and provides pressurized air for the aircraft’s environmental control system (e.g., ventilation).
Under the bill, the FAA must
- prohibit new turbine and turboprop aircraft designs from using bleed air systems,
- require (beginning seven years after the bill’s enactment) that any bleed air system in a newly manufactured aircraft is fitted with a filter (i.e., a device that removes gaseous and particulate components of oil fumes), and
- provide for a phaseout (over a 30-year period) of the use of bleed air systems in existing turbine and turboprop aircraft designs.
