Approach (α) and departure angle (β) of a vehicle. Approach angle is the maximum angle of a ramp onto which a vehicle can climb from a horizontal plane without interference. [1] It is defined as the angle between the ground and the line drawn between the front tire and the lowest-hanging part of the vehicle at the front overhang.
For helicopter movement, the chart shall provide information between the helicopter stand, the touchdown and lift-off area, and the final approach and take-off area; the chart should also supplement information along helicopter ground and air taxiways and air transit routes. In addition, essential operational information should also be provided ...
When an airport is being analyzed for designing an instrument approach procedure, an obstacle departure procedure assessment is conducted first.Pass the departure end of the runway, Surveyors establish an obstacle clearance surface (OCS), which is an imaginary surface that rises at a 40:1 ratio under standard conditions, or 152ft per nautical miles.
Along with clearance, length of overhangs affects the approach and departure angles, which measure the vehicle's ability to overcome steep obstacles and rough terrain.The longer the front overhang, the smaller is the approach angle, and thus lesser the car's ability to climb or descend steep ramps without damaging the front bumpers.

Approach / departure control facilities were created after adoption of radar in the 1950s to monitor and control the busy airspace around larger airports. The first air route traffic control center (ARTCC), which directs the movement of aircraft between departure and destination, was opened in Newark in 1935, followed in 1936 by Chicago and ...
PANS-OPS is an air traffic control acronym which stands for Procedures for Air Navigation Services – Aircraft OPerationS.PANS-OPS are rules for designing instrument approach and departure procedures.

The last section of the final approach is sometimes referred to as short final. Departure leg, Initial, [4] or Climb out. The climbing flight path along the extended runway centerline which begins at takeoff and continues to at least 1/2 mile beyond the runway's departure end and not less than 300 feet below the traffic pattern altitude.
