scope of NNCs. Aircrews are expected to accomplish NNCs listed in the QRH.
These checklists ensure maximum safety until appropriate actions are completed
and a safe landing is accomplished. Techniques discussed in this chapter minimize
workload, improve crew coordination, enhance safety, and provide a basis for
standardization. A thorough review of the QRH section CI.2, (Checklist
Introduction, Non-Normal Checklists), is an important prerequisite to
understanding this chapter.
Non-Normal Situation Guidelines
When a non-normal situation occurs, the following guidelines apply:
• NON-NORMAL RECOGNITION: The crewmember recognizing the
malfunction calls it out clearly and precisely
• MAINTAIN AIRPLANE CONTROL: It is mandatory for one pilot to fly
the airplane while the pilot monitoring accomplishes the NNC. Maximum
use of the autoflight system is recommended to reduce crew workload
• ANALYZE THE SITUATION: NNCs should be accomplished only after
the malfunctioning system has been positively identified
Note: Pilots should don oxygen masks and establish communications
anytime oxygen deprivation or air contamination is suspected, even
though an associated warning has not occurred.
• TAKE THE PROPER ACTION: Although many in-flight non-normal
situations require immediate corrective action, difficulties can be
compounded by the rate the pilot flying issues commands and speed of
execution by the pilot monitoring. Commands must be clear and concise,
allowing time for acknowledgment of each command prior to issuing
further instructions. The pilot flying must exercise positive control by
allowing time for acknowledgment and execution. The other
crewmembers must be certain their reports to the pilot flying are clear and
concise, neither exaggerating nor understating the nature of the
non-normal situation. This eliminates confusion and ensures efficient,
effective, and expeditious handling of the non-normal situation
• EVALUATE THE NEED TO LAND: If the NNC directs the crew to land
at the nearest suitable airport, diversion to the nearest airport where a safe
landing can be accomplished is required. If the NNC does not direct
landing at the nearest suitable airport, the pilot must determine if
continued flight to destination is a compromise to safety.

Approach and Landing
When a non-normal situation occurs, a rushed approach can often complicate the
situation. Unless circumstances require an immediate landing, complete all
corrective actions before beginning the final approach.
For some non-normal conditions, the possibility of higher airspeed on approach,
longer landing distance, a different flare picture and possibly a different landing
technique should be considered.
Plan an extended straight-in approach with time allotted for the completion of any
lengthy NNCs such as the use of alternate flap or landing gear extension systems.
Arm autobrakes and speedbrakes unless precluded by the NNC.
Fly a normal glide path and attempt to land in the normal touchdown zone. After
landing, use available deceleration measures to bring the airplane to a complete
stop on the runway. Circumstances dictate the need for an airplane evacuation or
if the airplane can be taxied off the runway.
Landing at the Nearest Suitable Airport
“Plan to land at the nearest suitable airport” is a phrase used in the QRH. This
section explains the basis for that statement and how it is applied.
In a non-normal situation, the pilot-in-command, having the authority and
responsibility for operation and safety of the flight, must make the decision to
continue the flight as planned or divert. In an emergency situation, this authority
may include necessary deviations from any rule to meet the emergency. In all
cases the pilot-in-command is expected to take a safe course of action.
The QRH assists flight crews in the decision making process by indicating those
situations where “landing at the nearest suitable airport” is required. These
situations are described in the Checklist Introduction or the individual NNC.
The regulations regarding an engine failure are specific. Most regulatory agencies
specify that the pilot-in-command of a twin engine airplane that has an engine
failure or engine shutdown shall land at the nearest suitable airport at which a safe
landing can be made.
