1. As the word says FWD- Forward fuel pump and an Aft fuel pump so either one could pump out the fuel to the user (engine). 2. Not my area 3. To pressurize or depressurize your system hydraulics 4. To allow bleed air to enter the aircraft pressurization system again either engine bleed air or APU bleed air. There is no dual supply there is a one way chk valve because engine bleed air is bigger it closes and shuts APU bleed allowing engine bleed only to the system. A fault lighy will illuminate in case of dual bleed failure. 5. Pack switches allow the crew to regulate the conditioned air to the cabin/flt. deck. 6. Isolation valve is to isolate the left wing from the right wing in case of wing/ body overheat or even trouble shooting left and right pneumatics or engine bleed. 7. Rejected Take-Off that is on the auto brake panel. 8. The only orange light I know is Amber light - it illuminates to signify there is a fault on that system. White lights when illuminated just signify they're in use. Ex. APU in Ground Power Panel illumninates a white light to signify avail for use ( electrical or pneumatic), A Blue light is below the APU Avail Light Switch in the flight deck APU panel -it signify ready for use or armed. But I think you're referring to the 3 lights that illuminates during landing -The outer marker ,let the pilots explain it better if this is what you mean. 9.Master caution is to alert the crew of an impending fault amber caution lt. for reminders and caution and red caution lt. for immediate requiring attention. 10, not applicable for me
ILS isn't locked onto. The ILS receiver picks up the localizer signal first, for left and right deviation of runway centerline. Once the aircraft gets closer to the runway, and a good glideslope signal is received, then the ILS is considered captured, and the steering information is displayed on the appropriate indicator(s) for left/right and up/down steering commands. Ours is on the ADI. This only happens if the aircraft enters the glideslope signal path from below. The ILS receiver is sometimes a combined LRU that has the VOR, Localizer Glideslope receivers, or they may be separate LRUs, as in a VOR/LOC Glideslope. The reason being that 2 different frequency ranges are used, VHF for VOR/LOC and UHF for glideslope.

Lock onto the ILS? There's a lock? Damn. That's 10 questions. This thing is worth 100 pts. I have a suggestion: restate all this in 10 separate questions so it's not so hard for us poor pilots. Our heads hurt after all that turkey. I'll answer the easy one. FWD means FORWARD or in the frontor towards the front and AFT means in the back or towards the back.
rust is caused by electrolysis and comes when 2 metals not the same come in contact with water, unless you replace all pipes with same copper then you will always have rusty water.
If the house is plumbed in copper you dont need redoing. You have old galvanized or old clay pipes somewhere. Check the tub first. Much cheaper to fix.
