When flying the OEM version (or any other aircraft with radio navigation and without GPS), I use a simple pencil/paper route plan. Usually I use Skyvector (and Navigraph charts for departure and arrival) to establish the route. Then I simply note down all segments of the route on a piece of paper, using my own shortcuts. In flight, I just follow the instructions I wrote down. Here's an example of a route plan for the route EGLC/EGGD:
route: EGLC/09 CPT6U CPT CPT1B EGGD/BRI.I09
transcript:
dep RWY 09 92° clb 520+ until ILST 111.15 D+1
int BPK 117.5 329° in
int BPK 117.5 272° out D+26
trk HEN 433.5
int CPT 114.35 225° in
int CPT 114.35 274° out D+32.4
trk BRI 414 @ FL070
hdg 278° IBON 110.15 D+8
trn left 107°
int IBON 110.15 87° intc @ 2,500'
dep = depart
int = intercept
trk = track
hdg = fly heading
trn = turn
This way I can break down a flight plan with SID, STAR and IAP into 10 lines with simple instructions. I find it easier to have all frequencies and courses noted down and ready at hand. Theoretically a fully fledged LIDO format plan would deliver the same information (plus a lot more), but for me it's harder to extract those bits from a bunch of paper sheets.
