Hi. Could not find a proper group to ask, sorry :
The old Boeing 707 and perhaps others had a tiny 3000+ psi air
compressor on board driven by a hydraulic motor to start engines with
NO ground equipment assist.
Which current aircraft have a similar compressed air starting system
on board ?
Thanks.

No civil AC I know of, except some russian light planes.

Bertie

Yeah, Mx probably doesn't know either.

I have done numerous "high pressure" starts in the old B-707. The air
compressor filled a "high pressure tank" and the tank then was
sufficient to start just one engine. After that, that engine's bleed
air was used to start the remaining engines.

Did the 707 not have an onboard APU?

Some did. Most not.


Bertie

Got a link?

I've een told, but haven't seen, that some have the 727 type installation.

I understand the 727 was originaly designed without an APU and they
squeezed one into the wheel well. This was the main reason it couldnt
be used inflight. This was from a systems instructor who had alot of
folklore on the 727 (Including the picture of 30 or so people hanging
on the airstair inflight during the fall of Siagon).

You are feeding a very destructive (wanna be) troll.

Could be. I only flew th e200 and they all had them. Of course, you
didn't really need one in flight anyway. There were plenty of electrics
available from the three engines anyway.

Mory bull****.
