Electrical systems, supplements, and ODPs

Electrical System is the most important system on the Diamond especially in IMC.  No backup source of power outside of the Battery. How long do you have before battery runs out?  What equipment is on essential bus? What is your strategy for dealing with an electrical supply interruption. Flight manual supplements need to be studied. Especially limitations on avionics and autopilot. This is very important for instrument pilots. Also pay attention to Obstacle Departure Procedures. If it says STD this means standard departure minimums or one mile visibility. Adhering to these procedures and visibility is critical to your safety on departure.  This includes the minimum climb gradients.
