Tucumcari Municipal (TCC). Tucumcari, NM.
Elevation: 4,065 Feet
Temperature: 24.4C/79.5F
Pressure Altitude: 4,050 Feet
Density Altitude: 5,997 Feet
The following conditions are the basis for data:
1) Flaps - - 10 DEGREES
2) Throttle - - FULL PRIOR TO BRAKE RELEASE
3) Runway - - PAVED, LEVEL, & DRY
4) Field ELEV > 3,000 Feet - - MIXTURE LEANED (see POH)
5) Wind - - ZERO

Starting at zero, you used 1,130 feet to achieve liftoff velocity. After liftoff you displaced an additional distance of 389 feet (total distance 1,519 feet) to acquire 66 feet AGL. This represents an average 445 ft/min climb rate. Obstacles, terrain, trees, buildings, towers, cranes,...the list is endless. Many pilots will choose to minimize takeoff weight. Others will choose to leave early in the morning or late in the evening to squeeze every ounce of performance from their aircraft. Safety factors are the key.
The pilot-in-command looks for safety factors. Examples are paved & dry runway. Takeoff in a headwind. Visual Meteorological Conditions. Daytime takeoff (in lieu of evening). Obtaining flight instruction from a certified flight instructor before attempting high density altitude flight is a worthwhile (perhaps the best) safety factor to pursue. Turbulence and wind gusts are understood in terms of acceleration (feet/second per second) not velocity (feet/second). Gusts & turbulence in and around ground effect are hazardous.
