All the complete but complicated explanations on how to use
Tacan and HSI, glideslope to barely come close to the efficiency of an ILS are fine.. BUT...
It is indeed VERY difficult to understand WHY ON EARTH the F-18 does not have an ILS...
Especially already having on board an ICLS for the carrier.
The a-10 C. Mirage 2000, C-101, and if I am not mistaken, the upcoming F-16 have it....
