Developing Personal Minimums  
Think of personal minimums as the human factors equivalent of reserve fuel. Personal minimums should provide a solid safety buffer between:  
.   
Skills required for the specific flight, and 
.   
Skills available to you through your training, experience, currency, and proficiency.   
 
Step 1 – Review Weather Minimums  
Step 2 – Assess Weather Experience and  
     Personal Comfort Level 
Step 3 – Consider Winds and Performance  
Step 4 – Assemble Baseline Values  
Step 5 – Adjust for Specific Conditions  
Step 6 – Stick to the Plan!  
Step 1: Review definitions for VFR & IFR weather minimums. Step 2(b):  Enter values for weather experience/ “comfort level.”

VFR  greater than 3,000 AGL  and  greater than 5 miles
