No loadmeter discharge

[testorius]

"Check for loadmeter discharge" is a required test for Twin Otters with built-in de-icing system. The current consumption display on the ammeter is used to check the functional capabilities of individual components. Normally checked individually, I have switched them all on.

 

No change on the ammeter. This is wrong.

I remember this was a discussion between Hans and one of the pilots.  They told us that they could hardly see any difference on their aircraft because they simply do not use a lot of electricity. We'll ask about that again.

If it is required in the procedures, you will also be able to read current changes.

 

I would ask the pilot to bring the aircraft into a low-consumption and therefore low-power state according to the checklist, then carry out the individual steps of the checklist and take a photo of the ammeter of each step. This is objective, quickly done and you would then also have the values by which the current strength must change. i think this can be implemented quickly in the programming, max 1h.

 

By the way, in section 9-1 De-Icing System under 9-1.4.6 After Start Engines there is another checklist item, which is also checked by the amperemeter.

PROP DEICE - observe loadmeter fluctuation indicating propeller de-icing cycling

 

With attention to detail and flight simulation, one would have to look at the complete de-icing system area in normal operating procedures and check the implementations.

I suggest to combine comments on the fuel system in one topic:
