In reply to FL270...

We usually leave off pack 1 all the time during boarding and on the ground unless absolutely necessary for temp control. Makes too much noise otherwise.

Also, what was said above about the ice test is what we call "Ice Test A" here. We only do the run up if we expect to hit icing conditions before we could complete the second part of "Ice Test B". Basically, Test A is a run up just like above. Test B is using the "Test 1/2" functions on the ice panel to test the annunciators, then in flight and below 10 deg C TAT we flip the ice to ALL for 30 seconds. Must be between 2000 ft and 23000 ft to do that.
