GENERAL:
* Situations resulting from mid-air collision, bomb explosion, catastrophic failure, or other major malfunction
* Selected elements of several different checklists may need to be applied to fit the situation
BASIC AERODYNAMICS AND SYSTEM KNOWLEDGE:
* Aileron control to serve as rudder control and vice versa - If both aileron and rudder control affected, the use of asymmetrical engine thrust may aid roll and directional control
* If elevator control is affected, stabiliser trim, bank angle and trust may be used to control pitch
* Pitch up with thrust increase, pitch down with thrust decrease
* Flight control break-out feature is incorporated onto the 767
* There should be no concern about damaging the mechanism by applying too much force to the control columns during break-out
* Limit bank angle to 15 degrees if manoeuvring capability is in question
* Trading airspeed for altitude and vice versa should be considered
FLIGHT PATH CONTROL:
* Take whatever action is necessary to maintain a safe flight path
* Fuel jettison (if installed) should be a primary consideration is performance appears to be critical
* If operation of flaps is in doubt, leading and trailing edge devices should not be changed unless performance requires such action
* Anytime an increased rolling moment is experienced during flap transition (indicating a failure to automatically shutdown an asymmetric flap situation), return the flap handle to the previous position
* On the ground during landing, aggressive differential braking and / or use of asymmetrical reverse thrust, in addition to other control inputs, may be required to maintain directional control
CHECKLISTS WITH MEMORY STEPS:
* Only after the flight path control has been established, do the memory steps of the appropriate non-normal checklist
* Complete all non-normal checklists prior to beginning final approach
* There may be times where two non-normal checklists conflict with directions. The intended course of action should be consistent with the damage assessment and handling evaluation
COMMUNICATIONS:
* Establish flight deck communications as soon as possible. This may require use of the interphone, or in extreme noise levels, hand signals and gestures
* Declare an emergency with ATC to assure priority handling and declare emergency services on the ground
* If possible, organise a discrete radio frequency to minimise distractions and frequency changes
* Squawk 7700
* Communications with the cabin crew and with the company are important, but should be accomplished only as time permits
DAMAGE ASSESSMENT AND AIRPLANE HANDLING EVALUATION:
* If possible, attempt to take time to assess the effects of the damage before attempting to land
* Make configuration and airspeed changes slowly
* Conduct the damage assessment and handling evaluation at an altitude that provides safe margin for recovery should flight path control be inadvertently compromised
* If structural damage is suspected, attempt to access the magnitude of the damage by direct visual observation from the flight deck and / or passenger cabin
* Consider contacting the company and use them as a valuable source of technical information if required from expert sources
* If controllability is in question, consider performing a check of the airplane handling characteristics. The purpose of this check of to determine minimum safe speeds and the appropriate configuration for landing
LANDING AIRPORT:
* The following items should be considered when selecting an airport for landing:
* Weather conditions (VMC preferred)
* Enroute time
* Length of runway available (Longest possible runway preferred, wind permitting)
* Emergency services available
* Flight crew familiarity
* Other factors dictated by the specific situation
