IFR LOFT Scenario

LOFT 9: Morristown to Allentown

Route: KMMU → KABE

Get-home-itis scenario with deteriorating weather and decision-making pressure.

View FAA WINGS activity on FAASafety.gov →

Scenario Overview

A "get-home-itis" scenario where the pilot is returning from a weekend trip with deteriorating weather, fatigue factors, and social pressure. Conditions that were VFR at departure time progressively worsen along the route, testing the pilot's ability to recognize and resist continuation bias.

Weather Scenario

A cold front is approaching from the west, moving faster than forecast. What was predicted to be a benign MVFR flight home is rapidly becoming low IFR. The TAF issued at 1730Z shows KABE deteriorating below minimums by 2100Z. The pilot has family commitments, a Monday morning meeting, and passengers who "need to get home." Each weather update shows conditions worse than the last, creating a classic get-home-itis pressure cooker.

Lesson Profile

Scenario timeline with phases, altitudes, and key events
PhaseTimeAltitudeEvents
Briefing & Scenario Setup0:00-0:15GroundSet the scene: Sunday evening, family waiting, work Monday. Brief weather that looks "doable" at MVFR. Review KABE approaches and alternate options.
Departure0:15-0:30187-5,000IFR departure KMMU. Light rain during climb. Initial conditions match the briefing. Seems routine.
Enroute - First Update0:30-0:455,000Receive updated KABE weather (1,200 OVC, 2SM). Worse than forecast but still above minimums. Decision point: continue or turn back while KMMU is still MVFR?
Enroute - Second Update0:45-1:005,000KABE drops to 800/1. Near minimums. KMMU behind you is now IFR too. The trap is closing. Instructor injects passenger asking "are we almost there?"
Approach1:00-1:255,000-394ILS RWY 6 at KABE. Gusty crosswind, turbulence on approach, break out near minimums or execute missed approach and divert.
Debrief1:25-2:00GroundAnalyze each decision point. When was the last safe opportunity to turn back? Discuss continuation bias triggers and mitigation strategies.

Post-LOFT Approach Practice

After the LOFT scenario concludes, practice 2 additional approaches for a total of 3 per session. Session is planned for up to 6 approaches — ask your CFII for additional practice.

Approach 2
KABE
ILS RWY 24
Opposite end ILS, vectors to final; practice precision approach from different direction
Approach 3
KABE
RNAV (GPS) RWY 13
LNAV+V approach to crossing runway, practice non-precision descent management

Training Objectives

Proficiency

  • Execute IFR flight in deteriorating conditions
  • Fly ILS approach to near-minimums
  • Manage approach to an unfamiliar airport under stress

Progress

  • Recognize get-home-itis and continuation bias
  • Apply the DECIDE model to evolving weather situations
  • Establish and enforce personal minimums in real time

Single-Pilot CRM

  • Communicate weather concerns to passengers (simulated)
  • Make assertive decisions despite social pressure
  • Request pilot reports and weather updates from ATC

Prepare for Your Session

What is get-home-itis and what psychological factors contribute to it?
Get-home-itis is the tendency to continue a flight into deteriorating conditions due to external pressures (schedule, social, financial). Contributing factors include plan continuation bias, sunk cost fallacy, overconfidence, and normalization of deviance.
What is the DECIDE model and how would you apply it here?
Detect the change, Estimate its significance, Choose a course of action, Identify options, Do the best option, Evaluate the outcome. In this scenario, each weather update is a "detect" trigger requiring re-evaluation.
What are the ILS RWY 6 minimums at Allentown?
DA of 594 feet MSL (200 feet AGL) with visibility of 1/2 mile (1,800 RVR). The approach also has a relatively steep glideslope for the terrain west of the field.
At what point should you commit to your alternate rather than attempting the approach?
When reported conditions are at or below minimums, when your fuel does not support a missed approach plus alternate flight, or when you recognize that the situation is emotionally compromising your judgment.
Instructor Notes
The key to this scenario is the emotional pressure. Set up the context convincingly — the student should feel the pull to continue. The weather deterioration is intentionally gradual to mimic real-world get-home-itis. Each update should be slightly worse. Watch for the student rationalizing ("it's only a little below..."). The teachable moment is recognizing the decision chain, not necessarily the approach itself.
