Altimeter is required for VFR day, but the regs only require the altimeter (pitot-static system) to be inspected 24 CM for IFR.
1. So, can you fly VFR with an altimeter that has exceeded the inspection date or that has never been inspected?
2. Which leads me to another question: if the airplane is equipped with a VOR that is overdue on inspection, is it still legal to use it for VFR? If, for whatever reason, the simple VOR inspection cannot be performed before takeoff or in the air, it would not be wise to use it for any serious navigation or even VFR practice approaches, right?
