I apologise , I misunderstood your query . . . . in Emer Elec Config WITH RAT as the only power source , you STILL do have RMP 1 and VOR 1 to navigate , when LAND RECOVERY is pressed you then recover ILS 1 .
In some of the later mods ( in this case ) even the ND 1 is still available with the RAT as the power source( which I have seen in the SIM ONLY ) that would depend on individual aircraft mod , hope this answers your question , you might have to check with the ramp rats for your aircraft specific .
