How to start engines by engine?

Recommended Posts

I am trying to find the procedure to start the DC-8 at gates with engine 3.. After push back how do i transfer air from engine 3 to engine 4 etc?

The manual, Youtube Videos, and forum all seem to only be talking about starting up all 4 engines in an aeriea with a lot of "soft traffic".

 

But is this the solution to get this to work?

NOTE: Normal operations should be from the same bleed source on each engine on a respective side. 
If two bleed switches on a given side are left in different positions, 
all the bleed air on that side will be supplied from the engine for which the switch is in the HIGH position. 
The pressure from the high-pressure source will then cause the low-pressure source bleed valve to remain closed or to close.

- page 29 operating manual..

 

We can't have the plane starting up engines at the gate area:glider_s:

Look forward to get it in the air...

You can absolutely start by bleed air once the first (no. 3) engine is started.  Once you have an engine running, turn off the ground air.  Then turn the low pressure manifold switch for engine no. 3 to HIGH.  Leave the others OFF until they are running.  Advance the thrust lever for the engine running until you have 30 psi of manifold pressure. Then you can start additional engines.
