Just repeated this, by heading directly at a copse, located just over the nose, using Slew. Bearing noted, then continued slewing until the copse just at right edge of centre screen; noted heading. Continued to slew until it was just disappearing from the right edge of the right hand screen. Doubling the angle differences to provide the field of view gave 52 deg for one screen and 104 deg for three. That agrees quite closely with the Hawarden observations.
How does that compare with the fron view on, say, the Chieftain?

I've just done a rough check, focussing on Hawarden, at a distance of 7 nm. Zoom was at 0.31, which most users think looks natural. It's also the minimum zoom value.
Turning to bring the field to the right edge of the centre panel produce a bearing of 279 (from FSNav), against n aircraft heading of 256.
Turning until the field is at the right extremity of the right screen leaves it bearing 281, against the aircraft heading of 228.
That seems to indicate an arc of view of about 106 degrees, compared to about 46 deg for the single screen.
i'm probably wildly out but it gives some idea of the differnce.

Only within 30 degrees either side of dead ahead though. Having said that I
know if you zoom out the angle of view increases - but I'm not sure how much
by. Maybe its an idea to create a compass turning circle in some scenery and
measure angles.

I must admit that it is tempting to try the TrackIR for formation work.

If Smithy ever unwelds his wallet, and invests in TripleHead to go, I'll give it a try. The forward view is probably wide enough to allow formatin on a reasonably close aircraft.

That's the standard procedure for any aircraft but it requires the
pilot(s) to permanently focus on the other aircraft - which is why a whole
formation tends to fly into the ground if the lead aircraft gets it wrong.

To watch the other aircraft in FS would require you using the side (or
forward side) view all the time. This can be done but it's a lot harder
than in a real aircraft. The problem lies in the fact that when you
bank an FS aircraft the whole outside view moves up or down. In real
life your eyepoint stay fixed on the other aircraft with bank not being
a consideration. The "fixed eyepoint" effect in FS can be very
disorientating especially if you alter bank a lot - as you certainly
would for formation work.

The Red Arrows managed it by formating at a trianglated position

ie the second craft hangs back a bit and below or the same level.

Then by looking at the lead ac lines up an agreed triangle

eg wing tip in line with leader tail plane and leaders wingtip lined up

the nose pitot, as a rough example.

This puts the following ac in an exact position. The pilot then just
has to maintain the correct altitude.
