I have a couple questions about the IFD Trainer, and possibly same with real unit (need to test in the plane). I'll ask here, even though the only IFD Trainer documentation is in the IFD100 manual (so this thread should perhaps be under IFD100).

1) Does anyone know how to set a GPS starting position for the aircraft in the trainer/sim? I know that this is done automatically as soon as a first waypoint is created in the new FPL, but I have a reason for not wanting the starting position to be the FPL origin.

2) Same question regarding setting the aircraft heading to start. There is a slider to set the aircraft heading, but this doesn't seem to have any impact. If I create an FPL in the trainer, the current aircraft icon/position is at the centre of the origin or first waypoint, heading north (360). Of course this is almost never the departure runway heading, so if a SID is programmed and then the sim started the aircraft heads off north and intercepts the SID at some point along the first leg, which is not realistic.

The sim and real IFD device can only have one origin programmed in the FPL, as the first waypoint. SIDs can only be programmed for this first FPL waypoint. It would be useful to able to add a SID to an airfield waypoint other than the origin. It is also not possible to navigate to the origin (if the flight starts from a different location that then FPL origin wpt).

I operate out of a VFR airfield and standard procedure for the Z FPL (VFR->IFR joining) is to proceed VFR to a nearby IFR airfield where clearance is given to join the circuit and then when low level over the runway in use, the tower issues an IFR SID clearance for that runway. The only way to program this into the IFD (or sim) is to set the IFR airfield as the origin waypoint in the FPL. If the cursor is on the origin waypoint and the D-> key is then selected on the ground at the VFR airfield before taking off, in an attempt to get guidance to the IFR airfield origin, a new direct-to waypoint is added after the SID instead. In other words, it is not possible to go "direct to" the origin in the FPL.

1. The only way to set the GPS start position in the trainer app is to set an origin.

2. The heading slider is only effective when there is no flight plan entered.

I think you've already hit on the best way to accomplish your scenario.  Enter the IFR airport as the origin, enter the SID, then go -D-> the origin (which will add the active leg after the SID).  Once you've reached the IFR airport and are ready to start the SID, move the cursor up to the correct leg in the SID and activate it.  You can then insert appropriate enroute legs after the SID.
