10 aviation questions for pilots.?

1. What does FWD and AFT stand for on the fuel pump switches?
2. How does an aircraft lock on to the ILS?
3. What do the hydraulic pump switches do?
4. What does the engine and APU bleed switches do?
5. What do the pack switches do?
6. What does the isolation valve do?
7. What does RTO stand for on the auto-brake dial?
8. What are the 3 orange, white, and blue lights for in the 737 or on any aircraft?
9. What is the master caution light for?
10. What does approach mode do during the final approach?
I don't have a real 737

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
