flight going to PHL......listed alternate as MDT.
Question arises from pilot about if MDT is valid. The forecasted ceiling at ETA was 800 bkn, greater than 6.
Captain calls and says he needs a different alternate due to the whole 1 navaid/2 navaid thing.
I was out of the room, and came into the conversation late as another dispatcher was on the radio with the capt trying to figure this out. When I came back I just obliged and gave him a different alt to get him out quicker without having to argue. MDT has an ILS 13 and 31, as well as a VOR 31. The ILS freq is the same from each direction.....the question I have is.....is it considered two different navaids if the Morse Code ident is different? I thought I remembered back in school that even if the ILS freq was the same, if the Morse code was different for each approach, it was considered two separate? Am I right or wrong on this?
Would have adding 200- 1/2 or 400 - 1 have been appropriate, and in either case does that get added to the mins for the VOR, or only the ILS if the ILS is the approach you plan on using?
I think I was right on this issue, and I hate second guessing myself.....but I just want to be sure.
thanks!
