What Are Some Environmental Factors That
Would Make Terrain “Unseen”?What about:
Night; Visibility; Obscurations; Others?
What Factors Other Than Environmental Could Make
Terrain “Unseen”?• Spatial Disorientation• Loss of situational awareness• Reduced reaction time to see & avoid• Optical illusions• Getting lost or off flight planned
route• Head down in the cockpit• Scud running• Distractions
What Factors Exist When Flying IFR / IMC?
• Currency / Proficiency• Current charts / plates / GPS database• Knowing when to say “Unable”• Knowing how & when to use equipment• Following MAP procedures• Knowing MSA & OROCAs• Improperly set altimeter• Unstable approach• Complacency

Consider: An Easy 2 Hr Flt From Chinle (E91) to Henderson
(HND) Las Vegas
Diverted to Winslow
24
Then Throw in Weather
MST Event
1400 Departed Chinle, AZ (E91), Monday, Dec 18
1445 Enroute Between Layers; Diverts to Winslow (INW)
~1515 Lands @ INW; Decides To RON; Spouse to Drive out (~5 Hrs)
~1615 Pilot Decides to Go South Around Wx
~1645 Returned to INW & Preflighted
1715 Departed INW
1724 Sunset; Twilight Ends 1754
~1830 Crash; 1+15 In The Air; 20 min Straight Line

Then Plan B - Also 2 Hr - And Throw In Night VFR into IMC

In What Ways is It Common to Other CFITs?
In What Ways is It Unique?
Total Risk Increases as Square of Factors Involved
Mountains = risk level 1Mountains + Weather = risk level 4Mountains + WX + Night = risk level 9Mountains + WX + Night + External
Pressure = risk level 16Mts. + WX + Night + EP + Unfamiliar route
= Risk Level 2525
