How to tune the Ils frequency?

[A320 pilot 1]

Hello,

i have read the manual of the Twin Otter but I  have no clue how to tune the Ils frequency in the GPS. Can someone help me?

 

Thanks and many happy landings.

Not sure I understand the question - you tune it on the NAV1 radio, just like a VOR. To tune NAV1 you may first need to push the centre-push switch of the radio tuning knob ('Push c/v') to select the NAV1 radio. (In the real GNS530 or the Reality-XP version it reverts to the COM1 radio after a few seconds so you always have to push it. In the Twin Otter Extended it stays on COM1 or NAV1.)
