o  Takeoff distance

o  Time & distance to climb

o  Cruise performance

o  Landing distance

.  
Are these performance values sufficient for the runways to be used and the terrain to be crossed on this flight?  

(Remember that it is always good practice to add a 50% to 100% safety margin to the “book numbers” you derive from the charts in the aircraft’s approved flight manual (AFM)).

Turbulence
.  
Are the wind conditions at the departure and destination airports within the gust and crosswind capabilities of both the pilot and aircraft?  (Note: For most GA pilots, personal minimums in this category might be for a maximum gust of 5 knots and maximum crosswind component 5 knots below the maximum demonstrated crosswind component.)

.  
What is the maneuvering speed (VA) for this aircraft at the expected weight?

(Note: Remember that VA is lower if you are flying at less than maximum gross weight.)

Ceiling and Visibility
.  
Is the forecast ceiling for my estimated time of arrival high enough to make the approach?

.  
What visibility can I expect for each phase of flight (departure, enroute, destination)?

--Will I have enough visibility to legally make an instrument approach at the destination?
