The login area is a resource that is quick & direct.  Like a Part 121 Airline Pilot, you now have interpreted data available to you. We already know what factually causes high density altitude. What is difficult to visualize is the overall ("all encompassing") environmental effect of this phenomena.

Here, pilots are able to affect an explanation, prediction and a means of control with respect to the contemplated flight. It is essential to flying safety that pilots contemplate an increase in takeoff distance, true airspeed & a decrease in rate of climb are each, valid consequences associated with high density altitudes. 

On this website, you will see mass & motion relationships that are associated with state of the art, new & modern single engine airplanes.  This is "prototype" performance where an engineering test pilot had the luxury of enhanced instrumentation to affect this level of predicted performance.  The general aviation pilot usually does not have the luxury of an air data computer (ADC) that will accept pitot-static inputs that output an electrical signal for highly refined intrumentation cues to benefit the pilot.  That's where this website is compensatory. 

You can now access critical content anytime to see the relationship of air density to aircraft weight, takeoff distance, velocity & acceleration. You can use this knowledge of prototype performance to better understand your personal FAA approved Pilot Operating Handbook. 

You are now going to undertake a journey, from one of my favorite places (Cedar Key, Florida [Levy County]) home of the Sea Breeze "on-the dock" Seafood Restaurant on Florida's nature coast. These are fictional flights that start from Cedar Key, FL but always have a fuel stop at some high density altitude airport "down the road."

Here, you want to compare air density relationships as they relate to ever higher performance aircraft that have inherently higher true airspeeds as a consequence of their inherent design & performance.  This means we start out with a relatively low power application at sea level, then we look at more power in concert with higher density altitudes. This is critical safety information for any pilot at any skill level contemplating high density altitude in piston airplanes. 

As an instructor, I am interested is presenting takeoff ground roll as a function of time that is a result of excess thrust.  As we transtion from a ground based vehicle to an airborne machine, we understand climb rate in association with a climb gradient, that is a result of excess power where Lift > Weight.
