Q

Graveyard Spiral Illusion

A

In a prolonged constant rate turn, sensation of the turn is not felt. In recovery to straight and level, the pilot may sense a turn in the opposite direction and pull back on the yoke, only tightening the spiral.

Q

Somatogravic Illusion

A

Rapid acceleration causes the illusion of the being in a nose up attitude. Rapid deceleration will have the opposite effect.

Runway Illusions
Runway Width - Narrow runway makes plane on approach appear higher than it is, resulting in low approach. Opposite for wider runway. Runway Slope - Upsloping runway makes plane on approach appear higher than it is, resulting in low approach. Opposite for downsloping runway.
26
"Single-Pilot Resource Management" (SRM)
Managing all resources (on AC and outside) available to a single pilot to ensure successful outcome of flight is never in doubt.
27
Examples of skills necessary for effective SRM?
ADM, risk management, task management, automation management, controlled flight into terrain awareness, and situational awareness.
28
What practical application provides the pilot with effective method to practice SRM?
Use of the Five P's. Pilot has 5 variables that impact his environment and cause pilot to make critical decisions that, when added together, create critical outcome. Used at points in the flight where decisions most likely effective (preflight, pre-takeoff, hourly, pre-decent, prior to entering pattern).
29
Five P's
The... P lan - NWKRAFT P lane - Airworthy? Documents? P ilot - IMSAFE P rogramming - Are you proficient using the avionics Are the GPS databases up to date? P ax - Are they nervous? Are they drunk?
30
"Aeronautical Decision Making" (ADM)
A systematic approach to risk assessment and stress management. The two defining elements of ADM are hazard and risk.
31
Basic steps in decision making process
Define problem Choose action Act Evaluate
32
Two models used to practice ADM?
DECIDE and 3 P's
33
DECIDE Model
``` D etect change needing attention E stimate need to react to change C hoose desirable outcome I dentify actions to control change D o something! E valuate ```
34
The 3 P's
P erceive P rocess P erform
35
Hazardous Attitudes
RAIIM - ``` R esignation - I'm helpless A ntiauthority - Don't tell me what to do! I mpulsivity - Acts without thinking I nvulnerability - It can't happen to me M acho - Watch what I can do! ```
36
"Risk Management" (RM)
Decision making process that ID's hazards, assesses degree of risk, and determine best action. Weighs potential costs against benefits.
37
"Hazard"
Present condition, event, object that could lead to accident Examples: Nick in prop blade, improper fueling, pilot fatigue, etc.
38
"Risk"
Future impact of hazard
39
PAVE checklist
Categories of risks. P IC - IMSAFE A ircraft - Airworthy? enV ironment - Wx, terrain, airport/runway, etc. E xternal pressures - Are my Pax urging me to get somewhere? Do I have stress influencing my life?
40
Why use a personal minimums checklist?
It helps pilot make decision based on what is smart and safe rather than simply legal.
41
Describe how 3P model is used for RM
Perceive the hazards for flight. Ask "what could hurt me, my Pax, or my AC"? Process the hazards by evaluating their impact on flight safety using CARE. Perform the best course of action using TEAM.
42
CARE Model to evaluate impact of hazard on safety
C onsequences of hazard A lternatives available R eality of situation E xternal pressures that might influence decision
43
TEAM Model
T ransfer the risk (Hire a flight instructor) E liminate the risk (Cancel flight) A ccept the risk M itigate the risk (Reduce risk)
44
Factors that can reduce a pilot's ability to manage workload effectively?
Environmental conditions - Temp/humidity extremes, noise, vibration, lack of oxygen Physiological stress Psychological stress
45
Options to decrease workload and avoid becoming overloaded?!
Stop, think, slow down, and prioritize. Delegate when possible. Use autopilot, if available. ATC may assist. Remember aviate, navigate, communicate!
46
How can tasks be completed in a timely manner without causing distraction from flying?
By planning, prioritizing, and sequencing tasks. With experience, pilots learn to recognize workload requirements.
47
Why should pilots use checklists?
To aid the memory and ensure critical items are not forgotten.
48
2 methods of checklist usage?
Do-Verify (DV) method Challenge-Do-Verify
49
Examples of common errors when using a checklist?
Items are missed due to distractions Items are performed incorrectly (rushed or read but not verified) Fail to use appropriate checklist for a specific phase of flight Safety compromised due to excess time spent looking at checklist Checklist not readily accessible Emergency checklist not readily available Memory items performed but not confirmed with checklist
50
11 phases of flight that should use checklist?
``` Preflight Before Start Engine Starting Before Taxi Before Takeoff After Takeoff Cruise Decent Before Landing After Landing Engine Shutdown/Securing ```
51
Methods for managing checklist accomplishment?
Touch/point at each control, display, or switch Verbally state desired status of each item When complete, verbally announce "_____ checklist is complete"
52
"Situational Awareness"
Accurate perception of all factors/conditions inside and outside aircraft that affect safety before, during, and after flight
53
Elements of situational awareness?
Inside AC - status of AC systems, pilot, and Pax Outside AC - Awareness of position of AC in relation to terrain, traffic, wx, and airspace
54
Procedures to ensure SA is maintained while flying a technically advanced AC (TAA)?
Always double check the system | Use verbal callouts
55
Additional procedures to ensure SA in TAA?
Perform verification checks of programming prior to departure Check flight routing - make sure it matches! Verify waypoints Use ALL onboard NAV eqiupment Stay within personal limits when using automated equipment Plan realistic route to maintain SA - ATC doesn't always clear direct route Verify computer data entries
56
Most CFIT accidents due to what factors?
``` Lack of pilot currency Loss of SA Pilot distractions and breakdown of SRM Failure to comply with min. safe altitudes Breakdown in effective ADM Insufficient planning ```
57
How to decrease likelihood of CFIT accident at destination?
Consider factors such as location, wx/daylight conditions, approach specs, ATC capabilities, type of ops, departure procedures, and crew config prior to flight
58
Operational techniques to avoid CFIT accident?
Maintain SA Adhere to safe takeoff/departure procedures Familiarize yourself with terrain and obstacles Stick to published routes and min. altitudes Fly stabilized approach Understand ATC clearances and instructions Don't be complacent
59
"Automation Management"
Ability to control and navigate by means of auto systems on AC
60
3 areas of proficiency when using advanced avionics?
Know what to expect How to monitor system for proper operation Be prepared to take action if system doesn't perform as expected
61
Most important aspect of managing autopilot?
Knowing which modes are engaged, which are armed to engage, and being able to verify that armed functions engage appropriately
62
At a minimum, the pilot flying with advanced avionics must know how to manage what 3 primary items?
CDI The navigation source The autopilot
