Free safety module 4 of 7Aviation Psychology & Risk Management11 min readLast reviewed: 2026-09-19
Recognize the hazardous attitudes, fatigue and outside pressures behind poor decisions, and apply the PAVE and IMSAFE checklists and a clear go/no-go gate before and during flight.
Scenario
Afternoon Return with Family and Approaching Last Light. You are on a private cross-country flight with your family on board, 45 minutes from home base. Official sunset is in 30 minutes and you do not hold currency for night flight. Fuel on board is 40 minutes — only 10 minutes above the 30-minute day VFR reserve required by 14 CFR 91.151 — and a line of building cumulus is developing near your destination.
Decisions and actions
Name the threat: the pressure to get the family home is an external pressure to manage (the "E" in PAVE), and pressing on into darkness or weather is the error it invites.
Run the IMSAFE checklist before deciding: Illness, Medication, Stress, Alcohol, Fatigue, Emotion — any one can degrade judgment at the exact moment a diversion decision is needed.
Divert early to an en-route airport reachable in daylight with the 91.151 fuel reserve intact, rather than stretching fuel toward closing weather or fading light.
Treat cloud as a hard boundary: without instrument training, flight into cloud quickly leads to spatial disorientation and loss of control — historically one of the deadliest accident categories in general aviation.
Safety traps
Plan-continuation bias: over-valuing the part of the trip already flown and refusing to divert.
Fuel exhaustion after holding or diverting with too little margin.
Spatial disorientation and an unintentional graveyard spiral in deteriorating visibility.
Check your understanding
1. What is "plan-continuation bias", and when is it most hazardous?
The habit of revising the flight log during smooth cruise
The unconscious drive to continue with the original plan despite evidence that conditions have deteriorated beyond safe limits — strongest near the destination
Always choosing an alternate airport further away than the destination
An instructor preference for standard VFR routes
Show answer
B. Plan-continuation bias is the tendency to stick with an existing course of action despite changing weather, fuel or daylight, and it becomes more dangerous the closer a pilot gets to the planned destination.
2. An airplane has entered an unintentional graveyard spiral. What is the correct initial recovery?
Pull back firmly on the yoke to stop the descent
Reduce power, roll the wings level with coordinated aileron and rudder, then ease smoothly out of the dive
Apply full power and trim nose-up
Extend full flaps to add drag
Show answer
B. Pulling back while still banked tightens the spiral and rapidly increases the load factor. Reduce power, level the wings first, then raise the nose smoothly — the same technique the PHAK teaches for recovering from unusual attitudes.
