  • Departure Procedures - Federal Aviation Administration
    VCOA procedures are developed to avoid obstacles greater than 3 statute miles from the departure end of the runway as an alternative to complying with climb gradients greater than 200 feet per nautical mile
  • IFR Departure Surface (40:1) and Climb Gradient | Airspace
    The standard aircraft departure climb gradient (CG) is 200 feet per nautical mile This value is designed to provide 48 feet of clearance at one nautical mile from the departure end of the runway (DER)
  • IFR DEPARTURE PROCEDURES · AFMAN11-217v1
    The 40:1 slope used by the TERPS specialist equates to a 152' NM gradient During the assessment, the TERPS specialist is required to provide a minimum of 48' NM or 24% obstacle clearance (Required Obstacle Clearance or ROC) to obtain the normal minimum climb gradient of 200' NM
  • Understanding Departure Procedures and its Two Different Types
    Your aircraft must climb at least 200 Feet Per Nautical Mile (FPNM) This is determined through an observed obstacle penetration slope of 152 FPNM If an obstacle does not penetrate the 200 FPNM climb gradient, the pilot has a minimum obstacle clearance of 48ft
  • How do I calculate FPNM for standard take-off minimums?
    Not exactly Feet per nautical mile is based on ground speed, not airspeed And like the chart shows, fpnm varies with temperature and altitude
  • Departure Procedures (DPs) - Aircraft Operations - CFI Notebook
    In all cases, continued obstacle clearance is based on having climbed a minimum of 200 feet per nautical mile to the specified point and then continuing to climb at least 200 feet per nautical mile during the departure until reaching the minimum enroute altitude, unless specified otherwise
  • On Instruments: Launch rules - AOPA
    The typical objective is to provide at least 48 feet per nautical mile of clearance above what’s known as the obstacle clearance surface (OCS), an imaginary surface that rises at a 40:1 ratio—this equates to a slope rising at a rate of 152 feet per nm
  • AIM - Chapter 5, Section 2
    In all cases continued obstacle clearance is based on having climbed a minimum of 200 feet per nautical mile to the specified point and then continuing to climb at least 200 foot per nautical mile during the departure until reaching the minimum enroute altitude, unless specified otherwise
  • (SIDs and DPs) 152 Feet per NM. . . - Jetcareers
    At Air Force bases, the plane starts at 0ft over the DER, and in the C-5 we're required to meet 200' nm climb gradient on four engines and 152' nm climb gradient on three engines So with all engines operating, you get a 48' buffer per nautical mile clearance over obstacles
  • Climb Gradient Question | Flightinfo. com - Share the passion of aviation
    A slope of 152 feet per nautical mile is assessed for obstacles If no obstacle penetrates this slope, the 200 feet per nautical mile climb gradient provides you with a minimum of 48 feet of obstacle clearance for each mile of flight
