Preflight Planning Dispatch Checklist
Background and rationale
Depending on the regulations under which an aircraft will operate, the FAA and ICAO have established provisions to ensure that appropriate information is gathered and considered before flight. It is extremely important for pilots to be well-prepared ahead of time with the information they will need to make good aeronautical decisions. If he/she waits until airborne, the pilot workload may become such that the pilot could be distracted by information gathering tasks when more critical tasks need to be accomplished to keep the flight flying safely. Or critical information simply may not be available to the pilot in flight that would have been available to him/her on the ground. Either case could lead to poor aeronautical decision making (ADM) and cause an aircraft accident or incident. The FAA has identified several "hazardous attitudes" in pilots that lead to accidents. One of which is "impulsivity". Even if a pilot does not demonstrate the "impulsivity" hazardous attitude, and believes he/she is performing adequate preflight preparation, without a checklist important preflight task items may be missed.
According to researcher and writer Atul Gawande, the concept of a pre-flight checklist was first introduced by management and engineers at Boeing Corporation following the 1935 crash of a prototype B-17 at Wright Field in Dayton, Ohio, killing both pilots. Investigation found that the pilots had forgotten to disengage a critical wing adjustment mechanism prior to take-off. Life magazine published the resulting lengthy and detailed B-17 checklist in its 24 August 1942 issue.[1]
The following checklist is developed to help aviators ensure they consider as much information as possible in the preflight phase so that they can make the best go/no-go decision possible and will be well-prepared once flying the flight where workload may constrain the ability to perform these tasks adequately. It is hoped that using this checklist, pilots can avoid the 5 P's: "Poor Planning leads to Poor Pilot Performance". Using a checklist can help as an antidote to the "impulsivity" hazardous attitude and can improve performance when time is of the essence.
Preflight information checklist
Pilot(s)
- I - illness
- M - medication
- S - stress and/or external pressures (get-there-itis)
- A - alcohol/drugs
- F - fatigue
- E - emotion - as listed in FAR/AIM SECTION 8.1.1(i)( only corrected letter E )
Be aware of any "hazardous attitudes" and use antidote if necessary:
Antiauthority: Don't tell me. Follow the rules. They are usually right. Impulsivity: Do something quickly. Not so fast. Think first. Use a checklist. Invulnerability: It won't happen to me. It could happen to any of us, especially me. Macho: I can do it. Taking chances is foolish and unnecessary. Resignation: What's the use? I'm not helpless. I can make a difference.

Weather
- sunset/sunrise

- SIGMETs=WST/WS and AIRMETs=WA (WST's issued H+55/2hr frcst; WS iss as nec./4hr frcst; WA iss 0845Z, 1445Z, 2045Z, 0245Z/6hr period, 3hr outlook, updated/corr. as nec., S=IFR/Mtn. Obs., T=Turb., Z=Icing)
- thunderstorms (Radar, Lapse Rate/Atmospheric Stability, Conv. SIGMET=WST)
- areas of marginal VMC or IMC (Satellite, ADDS Flight Path Tool Flight Category Display)
- (VFR flights) areas of mountain obscuration where terrain would require climb descent through ceilings even though VFR reported in valleys, or other areas where aircraft could get stuck VFR over-the-top
- icing (Current Icing Potential and Forecast Icing Potential on ADDS, FD Temps/Winds Aloft Forecast for frzing level, temps between +2 and -20 deg. C)
- PIREPs
- winds aloft and turbulence (don't fly with winds over 30 knots close to high/rough terrain; check FD for wind shear; 9900=calm, 731960=230@119,-60 deg. C, 7799=270@>199knots)
- locations of highs, lows, frontal crossings, airmasses (FA synopsis-18 hr. period, surf. analysis and sig wx progs)

ATC and route
- draw a line on chart for each leg with magnetic course and ETE

- special use airspace (SUA) including Military Operating Areas (MOAs) and Military Training Routes (MTRs)
- appropriate altitudes for terrain, obstacle, terminal airspace, SUA, TFR safe clearance, winds, turbulence, and regulatory cruise altitude per direction of flight; fly higher at night for increased gliding distance to landing areas.
