Reading did raise a question for me. When filling in the nav com section I usually put SG/S in.
I have on board:
GNS430 - With BRNAV/PRNAV
GTX - Mode S Transponder
DME/ADF/ILS/8.33khz
Am I using the correct entry?

Preceding the oblique stroke insert one or more of the following letters as appropriate:
N if no COM/NAV/Approach aid equipment for the route to be flown is carried, or if the equipment is unserviceable;
OR
S if the prescribed COM/NAV/Approach aid equipment for the route to be flown is carried and is serviceable;
AND/OR
D DME;
F ADF;
G GNSS;
H HF RTF;
I Inertial Navigation;
J Data Link;
K MLS;
L ILS;
O VOR;
R RNP type certification;
T TACAN;
U UHF RTF;
V VHF RTF;
W RVSM certified;
X MNPS certified;
Y Radio with 8.33 kHz spacing;
Z Other equipment carried.
Notes:
The definition of “prescribed equipment” allowing the use of the letter “S” (“standard”) is the carriage of the equipment represented by the letters “V”, “F”, “O” and “L”.
SSR Equipment
Following the oblique stroke insert one of the following letters to describe the serviceable SSR equipment carried:
N Nil;
A Transponder – Mode A – 4096 Codes;
C Transponder – Mode A – 4096 Codes and Mode C;
I Transponder – Mode S with aircraft identification transmission but without pressure altitude transmission;
P Transponder – Mode S with pressure altitude transmission but without aircraft identification transmission;
S Transponder – Mode S with both aircraft identification and pressure altitude transmission;
X Transponder – Mode S without pressure altitude transmission and without aircraft identification transmission.
N if no COM/NAV/Approach aid equipment for the route to be flown is carried, or if the equipment is unserviceable;
OR
S if the prescribed COM/NAV/Approach aid equipment for the route to be flown is carried and is serviceable;
AND/OR
D DME;
F ADF;
G GNSS;
H HF RTF;
I Inertial Navigation;
J Data Link;

I don't think you have PRNAV, bose-x.
The relevant nav accuracy bits of PRNAV requirements do appear to be met by any common IFR GPS (well if they are not it's hard to see how else they could be met; there is no more accurate method in the universe) but there is some other stuff which has been variously interpreted in its relevance to GA, and one interpretation appears to be that an EHSI (a HSI with the course pointer automatically rotating to the next track, at each waypoint) is required.
Personally I don't know but if somebody does know I'd like to hear about it.
