True that. I tried to find a photo on them of open in flight but I guess it's a tricky shot to take!

Maybe so! It's definitely a LIDS fence though, the engineers said so ;)

I've never heard or seen it called that! I can guess you can call it whatever though. The LIDS switch in the cockpit retracts the LIDS fence.

As mentioned, the auxiliary air doors on the outside of the intake are just hinged to open and closed under their own weight or pressure/vacuum in the intake. They are a bugger to fit. There is a second set of doors called the boundary layer doors, which sit on the inboard section of the intake, 2 each side. These are sprung loaded closed and open to vent off excess pressure in the intake. You can see them here, vertical just behind the intake leading edge.

On the Harrier, the LIDS fence and strakes are different components. The strakes are interchangeable with the gun pods. We used to sometimes fit gunpods because there wasn't enough strakes for the entire fleet. The LIDS fence sits just behind the nose leg and opens in certain configurations. U/C down and nozzles and/or flaps in a certain position. I'll have to check. Tusks were great for hanging your hivis/coat/bump cap/ear defenders on! The AV8B also flare launchers on the top of the rear fuselage, between the wing and the fin. As opposed to the GR7/9 which has a flare launcher underneath, just next to the airbrake.

The engine modes 'wet' and 'dry' were governed but the water switch position, gear selector and possibly nozzle position, my memory fades a little there. It's perfectly possible to demand water flow from an empty tank, which is never good. Zeus, I seem to remember the limit of short lift wet being 107%? I'll have a dig around in my old notes later.

Looks great! It was always fun doing a BIT test on the flap system, they would nearly bounce the aircraft off jacks.

I'm pretty sure the nozzles will be mappable to an axis, I'm sure that's how they are on the FSX version? The nozzle position is displayed on the EPI (Engine Performance Indicator), top right of the cockpit. Along with JPT, water flow, stab position, duct pressure, engine rpm and fuel flow.

Spot on! The Harrier system is called SAAHS (Stability Augmentation and Attitude Hold System). It also assists the pilot in a hover, with the RCS valves being mechanically linked to the control surfaces with rods.

Does the nose leg shorten itself to fit inside the nose bay?

The GR7/9s sometimes carried the gun pods if there wasn't enough strakes to fit in place, as they essentially did the same job as the strakes in the hover, forming the box section with LIDS fence, strakes/gun pods/tgp and airbrake.

Yup, also known as the DMT (Dual Mode Tracker). Harrier requires TIALD or Sniper to laser designate its own targets.

Bagpuss, did you have anything to do with IPaq? I remember messing about with that on the GR7s. Datalink on the Gr9 was a much more elegant solution!

Looks like there is an update to Anti-rad missiles in 1.5.6. Looking forward to seeing if this has fixed the problems.

The SU25T and weapons really needs some love. It's capabilities make it a unique aircraft in DCS :-/

This is more or less how the RAF came to upgrading to the Mk107 engine for the Harrier, which was much more suited to the high altitude and high temperatures. You can try reading about what happens when the Royal Navy end up in the desert. https://www.amazon.co.uk/Joint-Force-Harrier-Ade-Orchard/dp/0141035714/ref=cm_cr_arp_d_product_top?ie=UTF8

Any news on this? I keep getting asked to help out with SEAD duties and keep having to explain the bugs with these two weapons :-/

For airshow displays they used to run light. We used to take the pylons off to save a bit of extra weight and give them some more hover time.

It makes taking off in an overweight SU25T much easier though :)

Is there a shortage of kh58s at Blue airfields? I don't seem to be able to load them onto my SU25T. Not that they ever hit anything ;)

They can only really hover dry with the Mk107 engine, gave them that extra bit of thrust and essentially took away the need for the water tank. It stayed for ballast obviously.

Nice one Bill :) With the Mk105 and 107 engines the water is mainly there as ballast unless operating in high temperatures and/or altitudes. Otherwise, the water is used for water injection when the aircraft is set to 'Short Lift Wet' or 'Lift Wet' mode for hover and short take offs/landing. The engine is temperature limited so to get some more power the water is sprayed onto the turbine blades and around the combustion chamber to assist cooling and allow more fuel to be pumped in. The pump is air driven from engine bleed air, gives you about 90 seconds hover time.

That's a lovely looking model! :)
