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.” 
Category  Ceiling  Visibility  
VFR  greater than 3,000 AGL  and  greater than 5 miles  
MVFR  1,000 to 3,000 AGL  and/or  3 to 5 miles  
IFR  500 to 999 AGL  and/or  1 mile to less than 3 miles  
LIFR  below 500 AGL  and/or  less than 1 mile
