If you are at OSH and anxiously awaiting the arrival of Van's new iS airplane and want to discover all the little details up close and personal, then stop reading now. She is on the way today (Saturday) so should be there on display by Monday. Otherwise, I'll share some of the details I learned yesterday at Van's headquarters with you here.
Of course the fuel injected engine is the main attraction and that will no doubt be
the major source of discussions at OSH.
This is the airframe systems VR (marked B) and it is cooled by one of the ducts on top of the cowl:
The cowl VR cooling duct:
There is another VR for engine systems. Neither are Ducati.
Some of the bigger details include the center console with the new throttle. The detent is a stop at what is the best economy cruise, as I understood it:
Van's is experiencing significant fuel use improvement and a bit more power. Ask them about it.
The electric flaps are fast but not as fast as the johnson bar. There will now be a flap position indicator on the display. When toggling a Go-Around on the flap switch they will retract in about 3 to 4 seconds.
I also noticed that the ammeter on the display is "Generator" amps and not "Battery" amps as before. This in my opinion is more useful information if it shows the actual generator output.
And, there are a lot small details that may not be noticed in all the ballyhoo. Nice little details.
Like they added a holder for the oil cap on the oil door:
Those louvers in the top cowl are to cool the ignition modules, one of the many changes needed to adapt the iS engine to the 12.
More nice details:
The MLG entry points into the fuselage now have removable covers with rubber seals:
These I think will be retrofittable.
They have added strengthening gussets to the cockpit rails:
The gascolator is now behind the rear baggage bulkhead as is the ADSB-in black box. The ADSB antenna is now a small post type like the transponder antenna:
