If your engine tach is inop because the electrical device that displays
it is FUBAR, then you dont HAVE a tach per se to refer to.
What would it tell you?
One item would be wether or not you need to engage the starter in an
air-restart situation. If the prop is windmilling, then you already have
compression/airflow. Just need to add fuel and spark. Engaging the
starter isn't likely to help. If its stopped, then engaging the starter
would be a "really good idea (TM)"
Just one of the quirks of pushers without a bubble canopy.. hard to tell
if you are on fire.. hard to tell if you are streaming anything... and
hard to tell if the prop is turning.
