Ground lesson 23 (11) - Holding procedure

Holding procedures



  • Reasons for a hold
    • Spacing
    • Bad weather
    • Missed approach procedure 
      • Leads you to the fix where you hold until further instructions 
      • If you can't land for some reason
        • Losing glideslope or localizer (full deflection)
        • Can't see airport at minimums

  • Points of a hold

    • The fix
      • NBD, VOR, etc
      • Hold always begins at the fix

    • Inbound radial
      • The leg is always flown towards the fix

    • Fix end
      • The turn from fix to outbound leg

    • Outbound leg
      • Starts abeam the fix
      • The turn from outbound leg to inbound leg is called outbound end
  •  Holding procedure 
    • Standard patterns → right turns 
    • Draw a line 70º into the hold
    • 3 different suggested entries 
      • Direct entry
      • Teardrop entry  → turn 30º into the hold
      • Parallel entry → fly outbound for 1 min then turn into the hold and re-intercept

    • Fly each leg for 1 minute 
      • Adjust outbound leg so that inbound leg is 1 minute


  • Cross wind correction 

    • Use 3x the inbound correction on the outbound



  • Max holding speeds
    • 200 IAS at 6000 MSL and below
    • 230 IAS at 6001 MSL to 14000 MSL
    • 265 IAS above 14000 MSL

  • ATC holding instructions
    • Usually be issued 5 min before the hold
    • If there is a chartered hold ATC might say “hold as published” otherwise
      • Direction from the fix
      • Name of the fix
      • Course (from radial)
      • Leg length
      • Direction of turn
      • EFC time

    • Maintain altitude unless instructed otherwise 
    • Fly right turns unless left turns are assigned 
    • Always report time and altitude when reading holding fix
      • “Pdx approach, 4097L, Newberg VOR at 5000, 2300 holding south”

  • EFC time- expect further clearance 
    • Don't accept a hold without an EFC time 
    • Efc time allows you to leave the holding fix at a specific time if you lose communication
