Fokker 100 fans
Do we have any F100 experts here?
If you fly this airplane, you may like me, have heard as many theories as the type designator as to the operation of the aircon fans.
So, we have 'Econ', 'Pack', and 'Cabin' fans.
Ultimately, (my theory) it would appear that in essence, they can be seen as a "1, 2, 3" level setting for the flow of air through the airplane, ie. Everything off, level 1;
econ off but the other 2 on, level 2,
'Pack' off, level 3, etc. etc.
Is this correct?
Is it ok to turn everything off in flight? (Thats my personal preference from a noise perspective)
Would be very pleased to gain some knowledge on this topic.
Thanks.
