Make airships able to change altitude without using fuel

[candid geyser]

IRL airships change altitude using gas bottles and release valves, not fuel, so fuel shouldn't be used to change altitude in Aeronautica

So slight correction
They change altitude through releasing water (to gain altitude) and jettisoning hydrogen (to lose altitude)
Only exceptions to this ruel are Akron and Macon who used their gimballed engines to push/pull themselves to desired altitudes and then would use the water reclaimed fron running their engines to maintain buoyancy from using (burning) fuel

The only other exception might be Graf Zeppelin LZ 127
Who used blau gas for fuel so would just inflate the cells (with air) to drop altitude

okay

my point stands though

they shouldn't use actual fuel to raise and lower

[candid geyser]

and there are many systems used in airships, the one I said and the ones you said are all real

[bold warren]

I never said you were wrong

[candid geyser]

i know

i was saying were both right
