1 · Objective

By the end of this lesson your student can explain lost procedures in their own words, apply it in a realistic situation, and fly it to the ACS standard for PA.VI.D.

Why it matters for safety: Being lost is not dangerous on its own; running out of fuel, flying into clouds or terrain, or busting airspace while lost is. Pilots get into trouble when embarrassment stops them from asking for help, or when they wander and burn fuel. A calm, methodical plan turns being lost into a few uncomfortable minutes.

2 · Assign before the lesson

Pre-work: the free Train pack, Lost Procedures. Stay calm, keep flying, climb, use every tool, and ask for help early.

3 · Teach sequence

Key points to land

  • Fly the airplane first: hold a steady heading and altitude, and don’t wander looking for landmarks.(PHAK (FAA-H-8083-25C), Navigation)
  • Climb as necessary: you’ll see farther and get better radio and navigation reception, but only while staying VFR and clear of cloud, out of airspace that needs a clearance or contact you don't have, clear of terrain and obstacles, and when the fuel cost is worth it.(PHAK (FAA-H-8083-25C), Navigation; Private Pilot ACS (FAA-S-ACS-6C), PA.VI.D.S2)
  • Start from the last known position and time: heading, groundspeed and elapsed time give an estimated position.(PHAK (FAA-H-8083-25C), Navigation)
  • Use every tool: GPS, VOR cross-bearings, prominent landmarks, and ATC radar.(PHAK (FAA-H-8083-25C), Navigation)
  • The Five Cs, after flying the airplane: Climb, Communicate, Confess, Comply, Conserve. Ask for help early on a frequency you're already using, a charted ATC frequency, or Flight Service (122.2); use 121.5 only when you can't reach anyone or it becomes threatening.(PHAK (FAA-H-8083-25C), Navigation; AIM 6-1-2)
  • Don’t wait to declare an emergency if fuel, weather or daylight is running out.(AIM, Chapter 6, Emergency Procedures)
  • Keep track of fuel and daylight; if both are short, a precautionary landing at any suitable airport is better than pressing on.(Risk Management Handbook (FAA-H-8083-2A))

Finding your position

  • Recorded times over checkpoints are your lifeline: from the last known point, your heading, groundspeed and elapsed time give a circle of probable position.(PHAK (FAA-H-8083-25C), Navigation)
  • Look for large, unmistakable features: a lake, a highway interchange, a river bend, a city, then match them to the chart, not the other way round.(PHAK (FAA-H-8083-25C), Navigation)
  • Use GPS if it’s working. With VORs: tune and identify each station by Morse code or voice (never use one you can't identify), center the needle with a FROM flag to read the radial you're on, plot it from the station, and cross two radials at a good angle (not nearly parallel). Check the fix against your dead-reckoning estimate and a landmark before you trust it.(PHAK (FAA-H-8083-25C), Navigation; AIM 1-1-3)
  • Conserve: reduce power toward the POH best-endurance setting and lean as the POH allows. Know the 91.151 numbers: 30 minutes of fuel by day is already the reserve, so with that left, declare an emergency and land at the nearest suitable airport rather than keep searching.(PHAK (FAA-H-8083-25C), Navigation; 14 CFR 91.151(a))

Getting help

  • Confess and give them what they need: your call sign, "student pilot" if you are one, your last known position and time, heading, altitude, fuel remaining and persons on board. Then comply with their instructions, as pilot in command.(AIM, Chapter 6, Emergency Procedures; PHAK (FAA-H-8083-25C), Navigation)
  • A radar facility can vector you only if you can talk to it and you're in radar coverage. Its guidance is advisory: it doesn't authorize breaking a rule, and safe flight stays your responsibility. If you aren't instrument rated, say so, and say you're in VFR conditions; refuse any vector into cloud, and pick a VFR landing or declare distress instead.(AIM 6-2-1)
  • Other help: Flight Service on 122.2 or a remote communications outlet shown on the chart, and direction-finding (DF) steers from some facilities when radar can't see you, using just your radio transmissions.(AIM 6-2-3; PHAK (FAA-H-8083-25C), Navigation)
  • If you can’t reach anyone, use 121.5 MHz. Doubt about your position is an urgency condition ("PAN-PAN"); distress is "MAYDAY". Squawk 7700 only for distress or urgency when you want to alert radar, then make contact; for ordinary help, expect ATC to give you a discrete code to identify you.(AIM 6-1-2; 6-2-2)
  • Declare an emergency when fuel, weather, daylight or your own state is getting worse. You get priority. If you were given priority, ATC may ask for a detailed report, which you must file within the time they set.(AIM, Chapter 6, Emergency Procedures; 14 CFR 91.123(d))

Keeping safe while you work it out

  • Being lost makes you stare at the chart and the GPS. Keep scanning for traffic and terrain, and keep the airplane level and trimmed.(AC 90-48, Pilots' Role in Collision Avoidance)
  • Stress narrows attention. Slow down: fly the airplane, then use a checklist approach to position, then decide.(Risk Management Handbook (FAA-H-8083-2A))

Watch for in the airplane: Your instructor watches whether you stay calm, keep the airplane under control, climb when it helps, use the tools in a logical order, and ask ATC for help without hesitating.

4 · Ask your student

In order: recall, then understanding, then applying it. Move up only when the answer shows it.

  1. Recall · What is the emergency frequency and the emergency transponder code?

    A strong answer: 121.5 MHz and 7700.

  2. Understand · Why climb when you’re lost?

    A strong answer: You can see farther, and radio and VOR reception improve with altitude, so landmarks, navigation stations and ATC are easier to reach. Only if weather and airspace allow.

  3. Apply · You can’t match anything on the ground to your chart and the GPS has failed. What do you do?

    A strong answer: Hold heading and altitude, climb if I can, work out an estimated position from my last checkpoint and time, try two VORs for a fix, and call ATC for help. If fuel or daylight is short, declare an emergency.

Scenarios to talk through

  • After deviating around a rain shower you’re unsure of your position, with an hour of fuel and 40 minutes until sunset. What’s your plan?

    Sound decision: Don't turn on a guess. Hold a steady heading clear of the shower and note the time; work out a probable position from your last checkpoint, heading, groundspeed and the time spent deviating; climb if the weather allows; fix your position with GPS or two VOR radials; and call ATC now. Turn only once you know which way to go. With daylight short, plan to land at the nearest suitable airport rather than continuing.

  • You’re embarrassed to call ATC because you’re a student pilot. Should you call?

    Sound decision: Yes. Controllers help lost pilots routinely, and a call early is far better than an emergency later. Say you’re a student pilot: they’ll keep it simple.

  • You see a large lake ahead and find three lakes of similar size on the chart. How do you confirm which one it is?

    Sound decision: Check its shape, the roads and towns around it, and which one fits your estimated position from the last checkpoint and time. Confirm with a second feature before trusting it.

5 · Common student errors

  • Wandering in circles looking for a landmark.

    Why it matters: It burns fuel and destroys your dead reckoning.

    How to correct it: Hold a heading, and work from your last known position.

  • Waiting too long to ask for help.

    Why it matters: Fuel, daylight and weather options shrink while you hesitate.

    How to correct it: Call ATC as soon as you are unsure and can’t resolve it quickly.

  • Forcing the ground to match the chart.

    Why it matters: You convince yourself a landmark is the one you want.

    How to correct it: Go from the ground to the chart, and confirm with a second feature.

6 · Completion standard

  • Use an appropriate method to find your position, maintain an appropriate heading and climb as necessary, and select an appropriate course of action.
  • Your student answers each "Ask your student" question in their own words, up to the Apply level, without prompting.
  • They talk through the scenarios and reach a safe, legal decision, explaining why.
  • They complete the pack’s quick check and can say what they flagged.
