OK so today I talked to someone who seems to know what know what they are talking about when it comes to this stuff.
He said:
1. You can use the solo x/c PIC time from you private which we have established here.
2. You cant count the instrument time from your private.
3. Instrument time form private even though it was with a II does not count towards the 15 hours.
I think I may call the FSDO and see what they say.
Reference this:
(d)
Aeronautical experience. A person who applies for an instrument rating must have logged the following:
(1) At least 50 hours of cross-country flight time as pilot in command, of which at least 10 hours must be in airplanes for an instrument -- airplane rating; and
(2) A total of 40 hours of actual or simulated instrument time on the areas of operation of this section, to include -- (i) At least 15 hours of instrument flight training from an authorized instructor in the aircraft category for which the instrument rating is sought;
Question 1: Yes solo x-c time does count.
Question 2: Yes you may count any and all simulated or actual instrument that you have in your logbook regardless as long as it was completed in the same aircraft category.
Question 3: As long as the training was conducted with a CFII regardless of during private or instrument, it counts towards the 15 hours as is does not specify that it must be done as progress *towards* the instrument rating. (you will see the FAA specify if it has to be completed during the training for that specific certificate or privlige several times in the FAR's)
I personally would recommend utlizing a CFII for your training as it may be more beneficial that just 15 hours alone.
***Disclaimer*** As mentioned above, every FSDO and POI has their own interpretation of how those are meant to be taken...when in doubt, call ahead of time!
