Principles of Testing Outline General Principles Common Rating Errors Self-study handout
Principles of Testing General Principles A good test should be: 1) Valid 2) Reliable 3) Comprehensive 4) Discriminating 5) Objective
Principles of Testing Outline General Principles Common Rating Errors Self-study handout Validity
Validity Does test measure what it is supposed to measure? 1) make the test realistic 2) make the test complete 3) apply standards carefully 4) no test of items outside std
Validity Example Which is the most valid? 1) describe action in briefing 2) simulate action in aircraft 3) do action in aircraft 4) do action in simulator
Principles of Testing Outline General Principles Common Rating Errors Self-study handout Reliability
Reliability How accurately does it measure what it measures? Must be consistent: 1) Avoid extremes - distractions - aircraft - weather 2) Plan compensations (eg. V1) - beforehand - carefully
Reliability Example Which test is most reliable? 1) PPC in marginal VFR weather 2) PPC in good weather, light winds 3) PPC in good weather, strong winds 4) PPC in IFR weather near minima
Principles of Testing Outline General Principles Common Rating Errors Self-study handout Comprehensive
Comprehensiveness The test must include all the relevant sequences - important "need to know" info - do not focus on details - vary the program from test to test - change approaches, sequences, emergencies (where discretion)
Comprehensiveness Example Which test is most comprehensive? 1) departure, steep turns, hold, NDB, ILS 2) dep, hold, ILS, ILS, VOR 3) dep, hold, ILS, VOR 4) dep, steep turns, LOC (BC), PAR
Principles of Testing Outline General Principles Common Rating Errors Self-study handout Discriminating
Discrimination Detects different levels of achievement - separate qualified from unqualified - this is main goal of test - rank those who are qualified - use overall performance for borderline cases
Discrimination Example Which test is most discriminating? 1) no oral test before flight 2) oral test before flight with general briefing 3) oral test and specific test sequences 4) oral test before and during flight
Principles of Testing Outline General Principles Common Rating Errors Self-study handout Objective
Objectivity Test outcome must not be affected by personal examiner 1) do not impose your own standards 2) adhere to standards in FM, SOP, AOM and DCP Manual 3) do not let rating errors affect your assessment 4) carefully record events as they occur
Objectivity Example Which written assessment is most objective? 1) poor judgment during emergency 2) excessive swing during engine fail 3) altitude 100ft low inbd to beacon 4) airspeed unstable on final
Principles of Testing Outline General Principles Common Rating Errors Self-study handout
Common Rating Errors 1) Error of Standards 2) Error of Central Tendency 3) Error of Halo 4) Error of Logic 5) Error of Familiarity 6) Error of Narrow Criterion
Principles of Testing Outline General Principles Common Rating Errors Self-study handout Error of central tendancy
Error of Central Tendency Rate of performance at centre of scale Hesitant to give excellent or poor ratings Affects all assessments by this observer Most common with inexperienced observers
Principles of Testing Outline General Principles Common Rating Errors Self-study handout Error of Standards
Error of Standards Use personal standards to rate others If good at it - rate harder If poor at it - rate easier Affects all assessments by this observer
Principles of Testing Outline General Principles Common Rating Errors Self-study handout Error of Halo
Error of halo Allow general impression to affect rating Can be favourable or unfavourable Affects only certain persons rated Can include stereotypes
Principles of Testing Outline General Principles Common Rating Errors Self-study handout Error of Logic
Error of Logic When several similar traits Traits are related in mind of observer Could relate engine fail at V1 to SE landing Observer generally not aware of error
Principles of Testing Outline General Principles Common Rating Errors Self-study handout Error of Familiarity
Error of Familiarity • Grading objectivity weakened • Accustomed to weaknesses and eccentricities • Occurs over long period of time • Stop and regain perspective
Principles of Testing Outline General Principles Common Rating Errors Self-study handout Error of Narrow Criterion
Error of Narrow Criterion • Related to assigning rating • Often occurs in assessing two-crew or multi-crew assessments • One who does the best of perhaps a marginal performance obtains a high rating

Principles of Assessment Outline PPC general guidelines Assessment format Overall assessment
PPC general guidelines 1) Take note soon after event 2) Terminate test if failure 3) Allowance for turbulence 4) No advice, criticisms, training or demonstrations 5) Create realistic scenarios 6) Do not simulate multiple, unrelated failures
PPC general guidelines (con’t) 7) PPC - Use Designated Check Pilot Manual 8) Simulated weather at or below minimums 9) Need a "U" to fail 10) Take weather info into account in scenarios 11) PNF responsible if gross deviations, violations
Performance Assessment According to the following publications: • DCP Manual PPC - AFM - AOM, Pilot Operating Handbook - Operations Manual - SOP Manual IFT - Instrument Procedures Manual - Approach Procedures (Jepp) - Company Procedures
Principles of Assessment Outline PPC general guidelines Assessment format Overall assessment
PPC Assessment Format Sexercise flown within acceptable tolerances and procedures correct and effective SB a brief excursion from the criteria or a deviation from standard practices. Corrected by acknowledging the deviation during de-briefing; or regaining the criteria during flight U gross excursions from acceptable tolerances or a violation of airspace or clearance or a fault in procedure that could create an unsafe or ineffective situation
PPC Assessment Format S - Minor errors only - Airspeed and altitude control acceptable - Handling and knowledge are acceptable and safe considering the experience of the candidate
PPC Assessment Format U - Endanger aircraft, passenger, crew; - It results in a crash; - Multiple errors made in one exercise; - Violates ATC clearance or an altitude; - Major deviation from standard procedures or practices or safety was jeopardized; - Candidate required continued prompting or help from other candidate; - It exceeds aircraft limitations; or - Candidates demonstrates unsatisfactory knowledge of systems, equipment, or procedures
PPC Assessment Format SB - Aircraft handling and knowledge are safe but of a lower standard that can be corrected by briefing; - Brief excursion from tolerances but corrected promptly; - Deviated from SOP but did not create a more hazardous situation and is clarified by candidate - Candidate experienced some difficulty or required slight prompting to accomplish the task
Principles of Assessment Outline PPC general guidelines Assessment format Overall assessment
Overall Performance • is it safe and effective? • are criteria broken? • are any fail points done? • is crew concept used? • are crew in control of situation? • are procedues known and executed? • are limitations adhered to? • does an error create an unsafe situation? • are errors recognized and corrected? • would you send your family with this pilot?
