Instead of smashing anything you would be better off finding out in
advance where your static lines are. On my 182 I have two static ports,
one on each side, but no alternate static system. On the pilots side I
know where the tubing meets the fitting and can reach it while in
flight. You simply yank the tubing off the fitting and now you have
your alternate static source. And when you land there is nothing
expensive to fix.

Thought experiment:
1)Plug the static port.
Altimeter and VSI will never ever move again.

2)The Pitot pressure is ambient pressure + impact pressure.
If you climb then the ambient pressure goes down, but the ambient pressure
in the static system stays where it was because of #1 above air speed indicator becomes a backwards altimeter
biased by IAS.


This is exactly what happens. Been there done that.


Try to do some climbs decents and see if the Altimeter /VSI moves?

Obviously if you have an alternate static source that would be tried early on.


Pitot heat and alternate static, smash the hobbs meter.
