Very simple mod for ILS correction and Add Tower frequency to UKLN (use this addon with another free addon: https://flightsim.to/file/4762/chernivtsi-international-airport-ukln).
With this addon it will be possible to use published in charts ILS courses and frequencies:

ILS RWY15 - 109.5 - magnetic course 148;
ILS RWY33 - 110.3  - magnetic course 328;

Installation:

step 1. unzip folder into community folder (as usual)
step 2. Go to C:\Users\(username)\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalCache folder, open Context.xml file and ADD this text before row

 <Package name="yy-airport-ukln-chernivtsi" priority="(put here the next number that is in previous row)"/>

 , for example 

 <Package name="yy-airport-ukln-chernivtsi" priority="13"/>

.

P.S. IF you do not have Content.xml file, you can take it from my zip archive and skip step 2.
