All the JSF aircraft will use JPALS - it will be used for not only military but civilian use eventually.
Many of the elements of JPALS come from US civil aviation and not the other way around.
US civil air carriers regularly conduct WAAS & to a lesser extent LAAS (GBAS) approach operations on scheduled flights. You will more than likely see more LAAS operations in the future. I flew LAAS tests in a civil transport as far back as the 90’s.
I’m familiar with the FANS CPDLC that is currently incorporated in some Airbus aircraft and is used regularly over the North Atlantic and can and will eventually probably be used domestically. It is basically “text messaging” with a purpose.
US carriers are at present in the process of incorporating ADS-B generated CDTI displays. Once again, way back in the 90’s, CDTI was provisionally flown as a Mode S alternative to TCAS for the cargo carriers. The cargo guys eventually went with TCAS at that time, but with ADS-B, CDTI is big again for onboard traffic separation, sequencing and flow with minimal ATC input and potential for controller error.
The FMS in the B737-800 always has incorporated the capability for 4D navigation with LNAV, VNAV capability and an RTA (required time of arrival) entry available for departure, enroute & arrival fixes. Other Flight Management Systems will certainly provide this through software upgrades.
Instrument approach capability has always been somewhat secondary in the land based fighter business. Unlike the Navy fighter CLS systems, the original USAF F-100’s, F-105’s & F-4’s didn’t even have an ILS. The A-7 may have been the first USAF fighter built with an ILS installed. It’s ironic that student pilots were trained and were checked to do ILS’s in the T-38, and then assigned to fighters that had only TACAN or PAR approach capability. For awhile the T-33 was the preferred fighter trainer when it came to instrument flying and students who completed training in the T-38 and went to certain fighters got additional instrument training in the T-33.
The USN has RNAV approach capability in their TC-12 trainers and P-3's, but as of a few years ago they didn't use it operationally. I think the C-17 is the only USAF transport built with a certified RNAV approach capability, although it may have been retrofitted to E-3’s & KC-135’s & 10’s.
Civil aviation is way ahead on the more “mundane” capability and uses of GPS.

(BTW, in the old days before the T-37 got a transponder, you had to put the gear down for a PAR pickup. The original LO airplane.)
