Instruments II Flashcards
Define Holding:
A holding procedure is a predetermined maneuver due to unexpected or expected delays which keeps aircraft within specified airspace while awaiting further clearance from ATC
Reasons for Holding
Unexpected:
Expected:
Unexpected:
- Sequencing
- Emergency
- WX
Expected:
- Pilot request for practice holding
- Contained in original IFR clearance
- Course Reversal
4 Types of Holding:
- Arrival (Solid Thin Line)
- In Lieu of Procedure Turn (Solid Bold Line)
- Missed Approach (Segmented Line)
- Enroute
Banks in Holding
- Use whichever requires the least bank angle:
3° Per Second
30° Bank angle
25° Bank angle provided a Flight Director System is used
Airspeeds in Holding
Copter - 90 KIAS
0 - 6000 MSL - Max 200 KIAS
6,001 - 14,000 MSL - Max 230 KIAS
An ATC clearance requiring an aircraft to hold at a fix WITH a charted holding pattern will include:
- Aircraft ID
- Charted holding direction from fix
- The statement “as published”
- Expect Further Clearance (EFC) time
An ATC clearance requiring an aircraft to hold at a fix WITHOUT a charted holding pattern will include:
- Aircraft ID
- Direction of holding from the fix
- Name of the holding fix
- Holding radial, course, bearing, airway, or route on which to hold
- Leg length in time or miles
- Direction of turns
- Expect Further Clearance (EFC) time
Required radio calls for a holding pattern
- Entering Holding (Time and Altitude)
- Exiting Holding (Report Departure)
Abeam
Being approximately 90° left or right of something
Inbound Timing Factor
- 1 minute unless otherwise directed
- Wings level
Outbound Timing Factor
- 1 minute unless otherwise directed
- When abeam the fix or if unable to accurately verify, than wings level
Wind Drift Correction in Holding Pattern
- Only on Inbound and Outbound Legs
- Triple Inbound heading to receive the Outbound heading and opposite direction
