What is the difference between a normal checklist and a QRH item, and when is each used?

• A. QRH items are for routine operations
• B. They are the same
• C. Normal checklists cover standard operations; QRH items address abnormal or emergency procedures; use QRH for abnormal or emergency indications.
• D. QRH is optional

Answer: (C)

In flight operations, there are two kinds of procedural guides: normal checklists and QRH items. Normal checklists are the standard, step-by-step sequences used during routine, everyday operations to keep everything predictable and within normal limits—covering phases like preflight, startup, taxi, takeoff, cruise, approach, and landing. QRH items, on the other hand, are specifically for abnormal or emergency situations. They provide rapid reference procedures tailored to abnormal indications or system failures, guiding you through the priority actions and the correct order to address the situation. You consult the QRH whenever something abnormal or emergency-related occurs, using it to stabilize the aircraft and manage the issue, while memory items may be performed first if required before consulting the full QRH. So normal checklists handle standard operations; QRH items handle abnormal or emergency indications and are used whenever those conditions arise.
