 |
|
I'm communicating with an RV-6 owner who has noted interesting
altimeter movements as the aircraft slows down on the runway after
landing. He says that "from touchdown to stop, the alitmeter goes
down forty feet".
I'm betting the altimeter isn't getting much attention during the
landing roll, but I would be interested in hearing from anyone who
has paid attention to what it does.

Sounds like a static port issue (low pressure area around the static port).

Yes, this could be caused by static system position error. But, the aircraft supposedly has Van's standard pop-rivet static ports, so I wonder why this aircraft is different from the others. I have asked him to do a static system leak check, as this is another possible cause.
