Personally .... I don´t mess around with the Fuel System for any of our B727´s ....
Instead I just load the fuel I require (based on calculated flight/route requirements .... with additional reserve for holding or diversion etc) .... keeping as much fuel as possible outboard and within the wings.
If I´m undertanding your query correctly ....
The only time I use the Boost Pumps is during T/O, climb to cruising altitude, and then on the approach to landing also .... and for all other flight phases I just leave them "OFF"/alone.
So far as I´m are .... it´s possible to transfer fuel between tanks within these particular simulations. The complexity of various HJG simulations does vary in that this may be possible with some of our simulatioms, but, not with others. The reason for ths is simply because some of our panels were compiled by "ourselves and strictly in accordance with our own preconceived preferences" .... whereas other panels, being the work of external authors, ,were imported by us and which weren´t necessarily compiled in accordance with our preferences in mind. Despite the fact that some of these other have been extensively modified by us .... in some cases we weren´t able to incorporate everything we´d nomally have likes to have been able to include ... often for lack of having access to the original panel/gauge source code to enable us to do so/do more.
Best I can suggest is ....
1. Configure the Fuel sub Panel as is recommended within section
"2.06: FUEL SYSTEM SUB PANEL" of our following linked forum based manual (below) for the B727´s ....
"B727 PANELINSTALLASTION & BASIC FLYING GUIDE"tonymadgehjg.proboards.com/thread/7819/b727-panels-installation-handling-notes.... and use the Boost Pumps only during T/O, climb, and on the approach to landing.
PLASE NOTE: The above linked manual is one that Ive been able to restore all reference imagery to after the´recent PHOTOBUCKET debacle/imposition .... other manual imagery will be restored as and when Ive time to address these
2. After each of the 3 engines have started .... "don´t evér" mess around with any of of the 3 "guarded" Engine Fuel Cut Off Valves/switches located across the botome of the Fuel System Sub Panel. Leave those suckers alone .... or .... you could really end up in trouble with everythig suddenly/potntially going "quiet" on you
3. Again using the/my above linked forum based B727 manual (this coves almost everything anyone needs to know about these simulations and "not" just their installation process) .... refer to section
"5.00: B727 BASIC FLYING GUIDES" .... then .... identify the B727 version you´re actually flying from this list provided within this section of my manual ..... and load it (fuel and payload-wise) in accordance with my recomendation/s .... all of which are based on MGW with full payload and the fuel then adjusted accordingly. Each of these tutorials will/should assure you of "pretty good" range .... and range may be further improved by reducing Payload (both PAX and CARGO") in order to accomodate even more fuel quantity so as to promotte additional range.
Hope that helps .... and at least try out my above reommendations and mnual references
Are you flying the 1980´s ANSETT/POLYNESIAN/COOK ISLANDS INTERNATIONAl route from Sydney to Apia/Western Samoa (via New Coledonia), then on to both Rararotonga/Cook Islands and Auckland .... or .... the AUSTRALIAN AIRLINES/AIR VANIATU foute from Sydney to Port Vila/Vanuatu (via New Caledonia)?
Nice times those .... as I recall (routes and airlines I flew quite frequently) .... but ... sadly for both ANSETT and AUSTRALIAN these services didn´t last for either
These VH- registered aircraft (ANSETT, AUSTRALIAN, AIR VANUATU, COOK ISLANDS INTERNATIONAL, and POLYNESIAN "are" each represntednd within our B727-200 ADV downlods section
