Instrument Part 2 - Holding (Day 9) 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
- Published
- WX
Expected:
- Practice holding
- Published
4 Types of holding:
Missed approach (segmented line)
In lieu of procedure turn (solid bold line)
Arrival (thin solid line)
Published enroute holding
Bank in holding:
3* pr. second
30* bank angle
25* bank angle provided the flight director system is used.
- Use whichever requires the least bank angle
Airspeeds in holding:
Copter approach:
0-6000 MSL:
6.001-14.000 MSL:
Copter - 90 KIAS
0-6000 MSL - max 200 KIAS
6.001-14.000 MSL - max 230 KIAS
Unpublished Holding Clearance:
- Direction of holding from the fix in terms of the eight cardinal compass points (ie. N, NE, E, SE etc.)
- Holding fix or waypoint
- Radial, course, bearing airway, or route on which the aircraft is to hold.
- leg length in miles if DME or RNAV is to be used
- Direction of turn for a standard holding pattern is to the right
- Time to expect further clearance and any pertinent additional delay information.
Required radio calls for holding pattern:
- Entering Holding (Time and altitude)
- Exiting Holding
To be abeam something means:
Being approximately 90* Left or right of something
Timing factors:
Inbound
Outbound
Adjustments
When do you start the timer outbound a holding pattern:
What about inbound:
Inbound - 1 minute unless otherwise directed
Outbound - 1 minute unless otherwise directed
Adjustments - Always made on outbound leg
- Timer starts when abeam the fix or wings level on an intersection holding
- Inbound is always when wings level
Wind drift correction in holding pattern:
- Determine the drift correction
- Triple that number and apply it to the outbound heading.
Why does tripling the wind correction on the outbound leg not make sense?
Because you are so stupid you dont correct for the wind in your turn. - which is kinda hard when flying IFR
