1.6. Checklist Discipline. T.O. 1T-6A-1CL, The Pilot’s Abbreviated Flight Crew Checklist, is a condensed version of T.O. 1T-6A-1. The omission of a checklist item could lead to a dangerous situation. Therefore, positively confirm completion of all checklists regardless of how they are accomplished (e.g., memory aid, mnemonic, approved unit-developed checklist [UDC] or flight crew checklist). One technique to ensure accomplishment of every step is to execute a few items from memory; then reference the checklist page to verify completion. Further guidance on checklist use follows:

1.6.1. UDCs may be published to further condense many of the checklists used during ground and flight operations. UDCs often include multiple checklists on a single sheet that can be conveniently referenced without having to manipulate the flight crew checklist. UDCs are commonly color coded for identification of steps that need to be highlighted for easy reference.

1.6.2. It is not necessary to refer to the checklist during critical phases of flight as defined by AFMAN 11-202, Volume 3, Flight Operations, (e.g., terminal area operations including taxi, takeoff and landing, low level flight, tactical and formation operations (other than cruise), etc.).

p. 15

1.6.3. There will be only one pilot actively controlling the aircraft at any point in time. This pilot is referred to in the rest of this manual as the “pilot flying” (PF). The PF is responsible for initiating and completing all checklists as well as air traffic control (ATC) radio calls.

p. 15

1.6.4. Checklist items marked “(BOTH)” must be completed in both the front cockpit (FCP) and rear cockpit (RCP) (if occupied). The PF will initiate a “(BOTH)” checklist item by challenging the “pilot not flying” (PNF). A “(BOTH)” item is not complete until a proper response is received from the PNF. The use of this method of accomplishment is why “(BOTH)” items are often referred to as “challenge and response” items.

p. 15

1.6.5. Once started, attempt to complete checklists without interruption. If interrupted, or if it is discovered that an item was omitted, good techniques to get back on track include restarting at the first step of the checklist or restarting two to three steps prior to the missed or interrupted checklist step. Do not start a new checklist until completing the previous one.

p. 16

1.6.6. Throughout your flying career, many checklists and required items are memorized through mnemonics or standardized phrases. The purposes of these are to help you remember what needs to be done at a specific time. One caution is that you do not give “lip service” (i.e., expressed by words but not shown in action) to performing a checklist when using a standardized phrase or mnemonic. You must perform the checklist item or required check.
