🧩 S1–S2 – Skills: Operation and Checklist Application

Q: DPE: "Explain how a 'flow pattern' aids checklist discipline."

Physically trace cockpit sequence, then verify items against list—efficient and error-free.

Q: Why should pilots practice abnormal checklists often?

Builds muscle memory for high-stress response.

Q: DPE: "How can you demonstrate system management skill in cruise?"

Regular cross-checks of engine, fuel, electrical, and annunciators.

Q: Why are checklist flows customized per aircraft?

Panel layouts and systems differ by serial number or avionics.

Q: DPE: "Describe how automation mismanagement could fail a checkride."

Ignoring reversionary or standby procedures under G1000 failure.

Q: How does workload management tie into skill evaluation?

Efficient system handling leaves mental bandwidth for navigation and ATC.

Q: DPE: "Why must emergency procedures be memorized?"

Time-critical—no chance to reference manual initially.

Q: What's the DPE looking for during system checks?

Smooth control, correct terminology, understanding of system interrelations.

Q: DPE: "How can you safely simulate failures for practice?"

Pull breakers or switches with instructor supervision.

Q: Why do professional pilots verbalize checklist items aloud?

Confirms item complete, improves cockpit coordination.

Q: DPE: "How do you confirm system restored after reset?"

Verify normal indications and annunciator extinguished.

Q: Why must you confirm checklist completion visually?

Prevents missed steps during distraction.

Q: DPE: "How do you demonstrate fuel management skill?"

Track burn rate, switch tanks evenly, cross-check gauges/time.

Q: What separates proficient pilots from average ones in system handling?

Anticipation of failures, not just reaction.

Q: DPE: "Why end-of-flight checklist is still part of ACS evaluation?"

Ensures systems safely shut down and aircraft secured—discipline to the end.

Knowledge

Q: What does ACS Task G require the applicant to demonstrate?

Proper operation of at least three major aircraft systems using correct checklists.

Q: Why must checklists be followed in order?

Ensures no critical step is skipped or performed prematurely.

Q: What systems are commonly operated during a checkride?

Electrical, fuel, environmental, and flight-control systems.

Q: What's the purpose of challenge-response checklist use?

Enhances accuracy and teamwork (especially in multi-crew training).

Q: Why is "flow then verify" technique used?

Speeds operation while ensuring each item confirmed by checklist.

Q: When must system checks be performed in flight?

During all phases—climb, cruise, descent, and emergencies.

Q: Why is the before-landing checklist critical?

Ensures configuration, mixture, and systems ready for approach.

Q: What is the correct action if checklist doesn't match the aircraft?

Use the POH/AFM for that serial number or configuration.

Q: What indicates skillful system management to a DPE?

Smooth, timely, checklist-driven operation with situational awareness.

Q: Why use written checklists even after memorization?

Prevents omissions and builds professional habit patterns.

Q: When should the standby battery be armed?

Before engine start and verified charging after.

Q: What's the pilot's responsibility if a system operates abnormally?

Identify cause, follow checklist, and land as soon as practical.

Q: What should be verified after each checklist use?

Proper configuration and expected system indications.

Q: What is "automation management" skill?

Using G1000 features effectively without dependency.

Q: Why must the DPE see checklist discipline?

Demonstrates safe, standardized system operation.

Q: DPE: "During preflight, you find oil at 4 quarts—what do you do?"

Add oil before flight; below minimum (5 qt) per POH.

Q: You turn on master, but fuel gauges don't move—what next?

Check breakers and verify voltage; gauge failure means use fuel logs.

Q: DPE: "Show me proper electrical-system check before start."

Master ON, annunciators test, lights check, avionics OFF.

Q: Engine run-up—what do you check on mags?

125 RPM drop max, 50 RPM difference between mags.

Q: DPE: "Describe what you're checking during vacuum check."

Suction gauge 4.5-5.5 inHg—ensures standby gyro powered.

Q: During climb, low fuel-flow alarm appears—how handle?

Check fuel selector BOTH, mixture rich, boost pump ON.

Q: DPE: "Operate pitot heat and explain what you're verifying."

Amp rise and physical warmth confirm function.

Q: Alternator fails—how demonstrate checklist discipline?

ALT OFF, breakers check, ALT ON; if persists, shed load, land.

Q: DPE: "How would you confirm correct flap operation?"

Visual symmetry and flap-indicator consistency.

Q: Apply carb heat in older model (if equipped)—what check?

RPM drop then rise when removed; confirms function.

Q: DPE: "Demonstrate proper trim technique during slow flight."

Trim to neutralize control pressure at target airspeed.

Q: PFD reverts to reversionary mode—what do you do?

Verify essential bus operation, standby batt armed.

Q: DPE: "Describe your use of checklists during an emergency."

Memory items first, then reference written checklist.

Q: During descent, vacuum gauge drops—what's your reaction?

Recognize pump failure, rely on electronic attitude.

Q: DPE: "How do you verify cabin heat system operation?"

Feel airflow, check for CO detector, monitor for odors.

Q: In cruise, alternator light illuminates—demonstrate procedure.

ALT OFF, breakers check, ALT ON; if still low voltage, shed load.

Q: DPE: "How do you confirm fuel selector working?"

Switch briefly between LEFT/RIGHT while watching fuel-flow change.

Q: During preflight, CO detector discolored—fly?

No; replace before flight.

Q: DPE: "Why verbalize each checklist item?"

Ensures confirmation, reinforces procedural discipline.

Q: Pitot heat doesn't warm—what's next?

Abort flight; icing hazard, system inoperative.
