Four OCF Maneuvers
|
1. High AOA deep stall / rudder-induced departure
2. Low airspeed dep (70deg) 3. Low airspeed dep (110deg) 4. Lateral stick adverse yaw departure |
|
High AOA deep stall / rudder-induced departure
|
1. 20,000ft, clean
2. Idle, pitch 10deg (no trim past 150KIAS) 3. Note characteristics passing 21.5, 24-26 and 28-30 units (AOA, airspeed, sink rate) 4. Use rudder to maintain wings level 5. 1/2 rudder to 30deg AOB, full opposite rudder to depart 6. OCF Recovery 7. Passing 150KIAS, recover |
|
Low airspeed dep (70deg)
|
1. 300KIAS, 14,000'
2. 15-17 unit pull to 70deg 3. Idle passing 150KIAS 4. Departure = A/S <50 (0) 5. OCF Recovery (neutral, idle, boards in, analyze...) |
|
Low airspeed dep (110deg)
|
1. 350KIAS, 14,000'
2. 15-17 unit pull to 110deg 3. Idle passing 150KIAS 4. Departure = A/S <50 (0) 5. OCF Recovery (neutral, idle, boards in, analyze...) |
|
Lateral stick adverse yaw departure
|
1. 275KIAS, 20,000'
2. Set 15deg pitch 3. Roll 80-90deg, Idle 4. At 250KIAS: full aft & opp aileron (rudder neutral) 5. OCF Recovery (neutral, idle, boards in, analyze...) |
|
Low airspeed recovery (90deg, sim)
|
1. 350KIAS, 14,000'
2. 15-17 unit pull to 90deg 3. Idle passing 150KIAS 4. Recover passing 85KIAS 5. OCF Recovery (neutral, idle, boards in, analyze...) |
|
List 5 Phases of OCF Flight
|
1. Stall
2. Departure 3. Post Stall Gyrations 4. Incipient Spin 5. Steady State Spin |
|
Stall Buffet & Stall AOAs (Clean and Dirty)
|
Clean: 25...26
Dirty: 28...29-30 |
|
Define departure
|
- control inputs stop working
- airspeed is less than 85 KIAS - a/c rolls through 90deg AOB uncommanded following a stall |
|
Define poststall gyrations
|
Random and uncontrollable motions about any or all axes following a departure
|
|
Defining characteristics of incipient phase of a spin
|
Stalled AOA and rotation in direction of spin but not fully developed / stabilized
|
|
Defining characteristics of a steady-state spin
|
Self-sustaining yaw rotation and stalled AOA
|
|
Indications of impending departure
|
Mushy, unresponsive, buffeting, wing walk
|
|
What are the 4 primary instruments in spin identification and usefullness?
|
Altitude: time available for recovery
AOA: PDG, orientation, recovery Airspeed: steady-state Turn-needle: direction of spin |
|
What phase of OCF is indicated by: AOA above stall
|
Stall
|
|
What phase of OCF is indicated by: Loss of aerodynamic control
|
Departure
|
|
What phase of OCF is indicated by: AOA, turn needle, and airspeed osciillating
|
Post-departure gyration
|
|
What phase of OCF is indicated by: AOA and turn needle pegged, airspeed oscillating
|
Incipient phase of a spin
|
|
What phase of OCF is indicated by: AOA and turn needle pegged, airspeed steady or oscillating slightly
|
Steady-state spin
|
|
Define progressive spin
|
Second spin immediately following initial recovery from a spin. Usually opposite direction and violent.
|
|
Stall Buffet / Stall AOAs with emergency flap configuration
|
Stall warning @ 21.5 units AOA
Stall at 23-25 units Stall speed is 10 KIAS greater. |
|
Maximum airspeed for intentional directional departure
|
160 KIAS
|
|
Indications of a steady-state spin
|
Pegged AOA (0 / >28), airspeed between 50 and 160 KIAS, pegged turn needle
|
|
Altitude loss in a steady-state spin
|
At least 1,000' per turn and around 15,000 fpm.
|
|
What are recovery indications from an inverted spin?
|
AOA increasing above 5 units and yaw/rolling motions damping out
|
|
What are recovery indications from an upright spin?
|
AOA fluctuating/decreasing, yaw/rolling motions damping out, airspeed increasing
|
