Water injection system on 707/DC-8s

[mirageiiic]

Hi guys
I have a question regarding the water/methanol injection system modeled on the early 707/DC-8 models:  Is there a method for replenishing the water/methanol tanks once they have been emptied?  (i.e. shutting down on the ground and setting parking brakes, or connecting to ground power unit?)

I apologize if this has already been covered somewhere in the documentation, I searched but could not find an answer.

Thanks!

It has been discussed a number of time previously, but, "no problem" .... and in answer to your question ....

"NO" .... even the R/W aircraft had water/methnol capcity for "just one T/O only".

Water injection wasn´t constantly available.

Reading an anecdote authored by the late QANTAS captain BROWN, whom flew the B707-138´s when they were first introduced by QF during 1959 (and prior to their upgrading to fanjet power and -138B specification from 1960), he states this restiction was a real nuisance during training .... for the very reason only 1 T/O could be performed during which the W/M solution would be exhausted.

Using the HJG B367-80, B707-120, B707-138, DC-8-10/Ship One 1958, and both DC-8-11/12 .... the water injection system, once engaged, is available for "a timed 3 minutes only" before it´s then exhausted/is timed out .... about the same duration that was available for the R/W aircraft too.

The WI system can´t be replenished after exhaustion .... unless one lands, shutsdown, restarts, and performes another T/O (resulting in the system being auto-replenished by the simulations own programed routine) .... all within the same FS session and which is otherwise "pretty close" to reality.

Thank you for your help Mark! That is an interest anecdote too And my water injection system was indeed replenished after landing and shutting down. It's a very nice detail of this simulation and works quite well!
