A few comments have caught my attention..
Was going to be an option introduced on phase 7 upgrade; the wiring was all put there as part of phase 6 upgrade; also would provide option for a wingtip rail (akin to F16);twin sidewinder on GR.3's
but Phase 7 got canned by intro of the new GR.5
Certainly were removable; just wasn't an easily/quickly accomplished task; when pylon removed the harness was stowed in a 'blister' cover panel. Incidentally the Phase 6 upgrade introduced longer wiring harness to outer pylon too; (as well as white strobe lights; a Rad Alt and some other goodies) ; as the first Phase 6 wasn't done until 1983, the Falklands ones shouldn't have white strobes or rad alt either!inner pylons not removable
Fit was either pods or strakes; as combined with the small gear doors on main and nose gear; the space they enclose on lower fuselage forms an air 'dam' that increases lift in the hover by trapping rebounded (from ground) jet blast beneath the fuselage.Aden pods
Incidentally some 'Falklands War' GR3's flew with an empty gun-pod converted to house the Blue Eric jammer (Google it).
Problem with VFF ; particularly for GR.3's was the fatigue life penalty that was applied;VFF
IIRC each VFF was counted as 5 'normal' flights. Wings and fuselage were separate 'lifed' components; and would have to be swopped around regularly to even out the fatigue life consumption. The RN did practice VFF; but IIRC none of the air-air combat's in Falklands required use of the technique; the SHAR was naturally more agile.
Ps How about the extended 'Ferry (wing) Tips' to go with the big 'Ferry' external wing tanks...
Now, to wings and pylons...(I spent my last 6 months in RAF overhauling Harrier and Sea Harrier wings; @ 1992); it was usual squadron practice for all four pylons to be fitted; and within that description, the two inner pylons would normally have external tanks mounted; leaving the outers and centreline to carry things wot go bang.
As Bazzar pointed out earlier there was a weight/performance balancing act to be performed; especially when certain flight profiles meant use of 'hover' modes; removal of outers (each outer pylon is @ 2 hours work to remove and/or fit) would be because the flight profile and planned load-out demanded it for weight-saving.
Inner pylons; although removable; were rarely removed once fitted as they took even longer to remove and/or fit.
Hope this helps.
Pete, you should write a book on this stuff, your insights into working with the Harrier are fascinating!
When we started this project for Wilco, we thought, where the hell do we start? The amount of info one needs to accumulate and digest is enormous on this type of aeroplane.
Then of course you have to teach the sim not to be so silly and obey all these new commands.
Pete obviously has a vast amount of experience knowlege, we have just scratched the surface but have endeavoured to provide as realistic a simulation as possible. There will always be errors of some sort or another but that is what upgrades and patches do. As new info comes to light or as we learn more we can adapt the project.
It is interesting though. just how much knowlege we have to accumulate on different aircraft,from biplanes to airliners. We'd probably do well in a quiz show!
One other thing I read in sharkey wards book was that they'd drop the nossels 80 degrees while keeping the throttle at idle with full flaps down on approach to the carrier to slow the aircraft, he actually says that it was like having 4 airbrakes but was different from a VFF, as soon as the speed started getting down around 120kts power would be applied, water injection switched on then finally the gear and airbrake would be deployed, really can't wait to fly the SHAR what a huge miss the aircraft is over here!

I havent the foggiest idea - What is "VFF"?
Well, it's either the Vietnamese International Film Festival or...
Vectoring In Forward Flight. A technique used in VTOL aircraft whereby the ability to use vectored thrust is used to reverse direction or rapidly slow the aircraft allowing the "enemy" to overshoot.
As already mentioned earlier, VIFFíng was not really encouraged as it put enormous strain on the Harrier airframe, especially when carrying heavy payloads.
VIFF is used during the following clip.
I won´t see your signature.
pleasantly surprised to find download version is already available... very pleased. Great work AH
