"On board" computers
by Azzurro

Fly! II planes use various "on board" computers, thus usable during flight.

Fly! systems

1°) Basic or old planes don't have any computer:
- it's the case for the Stearmann among TRI planes.
- same case too for ROTW planes: PA19-L18, PA28, P51 Mustang, Staggerwing.
Some of these planes have only either one NDB receiver or one/two VOR receiver(s) or both (NDB+VOR).

Navigations are done visually, but nothing prevents you from doing important distances by using all possibilities we can find into the plane: our elders flew around the world with "a compass and a watch" only. These techniques have been thoroughly tested, and you will be happy to know them if GPS breaks down.

2°) Planes using the KLN89 GPS computer
It's the great majority of other planes, from Flyhawk up to top-of-the-range propeller aircraft as TBM, B1900, Seneca or Kingair.

It's an excellent device, full of resources, and which requires that we cram the documentation and we made tests. You should not hesitate to switch on it from time to time in "pop-up" mode (key N) to reach supplementary functions and have a better reading.

... and in "FPL" function (flight plan)


In order to know how this GPS works, refer to the Fly.Simvol page.

3°) Jets using the FMC
It's at first the Hawker (Peregrine), as well as most of jets, created "free", and which use the same base.

The FMC is an impressive machine, with two side by side beautiful and very legible screens, but regrettably it offers few features, many buttons are ineffective. In fact, it's less outstanding than the above GPS receiver, except to estimate the time at successive points.


--> A trick discovered by Tony Cervone applies both to the GPS and to the FMC, it's worth speaking about it. Here is the continuation.

Other systems

1°) ROTW 230 and ROTW 350 computers:
They're new computers, developed by Laurent and TJ. They offer some clever possibilities. Refer to the relevant pages on Fly.Simvol.

2°) PMDG (TM) planes (757 and 777)
We mention them for the record, these aircraft' computers are much elaborated, and they are considerable success (although the documentation to be ingested is extremely thick).
Ideal for long flights above FL250 with SID, STAR and Airways.

3°) The ND (Navigation Display), another creation by Laurent and TJ
We are now close by the concept of a "glass cockpit" of the future. It is a "demo" product.
It already works fine on TRI's Malibu (Sahara). We should see it working on future planes, now on development.
