fixed F-16 EGI / INS GPS

[SpaceMonkey037]

hello, I have done some research on the F16s navigational systems and our F-16 does not have EGI although according to the DCS manual we do have EGI. If we would have had EGI it would have said EGI instead of INS on the INS knob on the avionics power panel. Furthermore, EGI allows for something like 5000 steerpoints, while INS and GPS can only have 127 steerpoints like our F-16 currently has. Could this be this a mistake in the DCS F16 manual?

I wonder if those 5000 steerpoints are in part GPS steerpoints. In hornet for example you have 60 waypoints and a further 200 GPS waypoints.

Pretty sure the manual is wrong, I think mvsgas might now for certain

I have mention this before.

Edit

Not specific by block. Depends on the year and country, or best would be year and specific tail number/serial number. Laser Ring Gyros where introduce on TCTO 1F-16-2255 and it should have been completed around 2001, EGI where introduce on TCTO 1F-16-2489, and by 2010 was not completed. The EGI panel was introduce after OFP M5.1+, TCTO 1f-16-2570. Again, not completed by 2010. To know what aircraft had RLG/INS + GPS and which had EGI you would need to know when these Time Compliance Technical Orders (TCTO) where completed on those aircraft.

USAF F-16C block 50 circa 2007 still using RLG Part Number 890500-203 and prior to TCTO 1F-16-2489 and TCTO 1F-16-2570

 

The avionics power panel would look different for that versions. Instead of INS it would say EGI and there would be no GPS power switch.

 

The fact that we need 8 minute alignment tells me this is not an EGI. But the INS and GPS work together. This is those times where it was not just INS but INS with GPS.

I will ask the team to confirm, when I get an answer I will let you know

Could this be the correct AVIONICS POWER panel for our model?

Interesting that there is a GPS switch there even though it's an EGI model. I guess it could have one of several functions.

• could be inop
  
• could independently switch the power to the EGI's internal GPS receiver -- it's useful to be able to power cycle a GPS receiver without clearing the blended inertial navigation data
  
• could control whether the EGI incorporates GPS data into the navigation solution without affecting the GPS receiver power
  
• could control power to the GPS electronics upstream of the EGI's GPS receiver, such as the L-band filter(s) or the low noise amplifier (no direct knowledge but I assume these exist on the Viper)
  

Any of the last three would have an equivalent effect, namely to cause the EGI's navigation solution to use only the EGI's INS, which increases inertial drift, but allows the pilot to cut out the GPS receiver if there are problems, either with the receiver itself or with a hostile GPS environment (think spoofing).

All EGI references were removed from the DCS manual.
