Kore Aviation - When you're flying and something doesn’t feel right, you need a strategy. Whether you’ve missed an approach, gotten off course, or are unsure of your exact location, there’s a proven mental checklist every pilot learns: the 5 C’s of aviation.
Even with GPS and advanced avionics, these steps remain relevant. Technology can fail, and human error happens. This article unpacks when and how to use the 5 C’s, how they apply to lost aircraft procedures and go-arounds.
What Are the 5 C's of Aviation?
The 5 C’s are a simple set of steps pilots follow during uncertain or emergency situations in flight. They’re especially helpful when a pilot becomes disoriented, lost, or unable to land safely.
Here’s what they stand for:
- Confess – Acknowledge you’re lost or uncertain of position.
- Climb – Gain altitude to increase visibility and radio reception.
- Conserve – Save fuel and avoid unnecessary maneuvers.
- Communicate – Contact air traffic control or use emergency frequencies.
- Comply – Follow any instructions given to regain control and return to safety.
These steps used in real-world scenarios to help pilots manage stress and make the right decisions fast.
When Do Pilots Use the 5 C’s?
The 5 C’s come into play in two main scenarios:
1. Lost Aircraft Procedures
If a pilot is unsure of their current position, the 5 C’s guide them through regaining situational awareness, contacting ATC, and following a recovery path.
2. Missed Approaches or Go-Arounds
In cases where a safe landing isn’t possible, the pilot must execute a go-around. A different version of the 5 C’s applies here, more focused on aircraft control and flight path correction.
Using the 5 C’s in a Lost Aircraft Procedure
Becoming unsure of your position mid-flight can happen. Weather, distractions, or malfunctioning instruments can contribute. When it does, here’s how each step of the 5 C’s works in this context:
1. Confess
Don’t wait too long. If you suspect you’re lost, admit it. To yourself and to ATC. Early action makes recovery faster and safer.
2. Climb
Altitude is your friend. It increases radio coverage, gives you a better visual range, and buys you time in case of terrain or obstructions.
3. Conserve
Don’t overfly or take unnecessary turns. Level out, reduce power to cruise or endurance settings, and preserve fuel.
4. Communicate
Try your current frequency. If that doesn’t work, switch to 121.5 MHz (emergency). Share your last known position, altitude, heading, and flight condition.
5. Comply
When ATC gives directions, follow them. Don’t delay or try to correct on your own. The quicker you comply, the sooner you’ll be safely back on course.

Pro Tip: Keep the 5 C’s Visible
Pilots are trained to memorize the 5 C’s, but having them visible in your cockpit makes it easier to act under pressure. Add them to your checklist, flight bag, or kneeboard.
Mid-Flight Situations Where the 5 C’s Save Lives
Let’s look at some practical flight scenarios:
- Weather closes in, and you can’t see landmarks – Use the 5 C’s to stabilize and get help.
- GPS failure mid-route – Climb and conserve while navigating with backup methods.
- Lost in uncontrolled airspace – Call for help, get vectors, and comply with ATC instructions.
- Fuel state becomes questionable after getting lost – Use the Conserve step aggressively and prepare for alternate landing options.
What About Go-Arounds or Missed Approaches?
When you’re on final approach and realize you can’t land safely, the decision to go around is critical. Here, the 5 C’s adapt slightly:
- Cram – Apply full power immediately.
- Climb – Establish a safe climb attitude and rate.
- Clean – Retract flaps and gear as appropriate.
- Cool – Manage engine and systems for climb performance.
- Course or Call – Get back on course or communicate your intentions with ATC.
Why Every Pilot Needs a Reliable Headset
One of the most important C’s is Communicate, and communication only works when your gear is reliable.

The 5 C’s Checklists: Quick Access in the Cockpit
Having a printed or laminated version of both 5 C’s checklists in your flight kit makes a real difference. Use this layout for reference during preflight briefings or in-flight review:
Lost Aircraft Procedure (5 C's)
| Step | What To Do |
|---|---|
| Confess | Admit you’re unsure of position |
| Climb | Gain safe altitude to increase visibility and signal reach |
| Conserve | Reduce power, fly steady to save fuel |
| Communicate | Call ATC or emergency frequency with your info |
| Comply | Follow instructions exactly |
Missed Approach / Go-Around (5 C's)
| Step | What To Do |
|---|---|
| Cram | Apply full throttle and stabilize aircraft |
| Climb | Establish climb rate and airspeed |
| Clean | Retract flaps/gear as required |
| Cool | Monitor engine and system temps |
| Course/Call | Turn to missed approach path or call ATC |
Printing these on durable cards and attaching them to your kneeboard or yoke is a great habit.

Why the 5 C’s Are Still Relevant Today
With modern GPS, ADS-B, and digital avionics, you might think the 5 C’s are outdated. But technology can and does fail. Pilots are still vulnerable to:
- Instrument misreadings
- Loss of GPS signals
- Weather-related disorientation
- Airspace violations due to off-course errors
The 5 C’s don’t rely on technology. They’re a mental framework that works in both high-tech and low-tech cockpits. Whether you’re flying a Cessna 172 or a Cirrus SR22, these actions still apply.
Pilot Training and the 5 C’s
Flight schools and CFIs teach the 5 C’s early because they’re easy to remember and practice. But memorizing them isn’t enough. Here’s how to reinforce them:
1. Practice During Sim Sessions
In every ground-based or full-motion simulator, insert lost comms or navigation failure scenarios and act out the full 5 C's procedure.
2. Use In Every Approach Briefing
Add a missed approach segment to your pre-landing brief. Think: “If I need to go missed, I’ll Cram, Climb, Clean, Cool, and Call.”
3. Create VFR and IFR Flashcards
Keep a quick-study set in your flight bag. Review them before flights.
4. Debrief Every Flight
Ask yourself: “If I got lost today, would I remember the 5 C’s?” Assess what worked and what needs improvement.

Beyond Basics: Customizing the 5 C’s for Your Flight Environment
Different aircraft and airspace environments may slightly shift how the 5 C’s apply.
Mountainous Terrain
Climbing may not be possible right away due to terrain. Instead, assess whether you’re in a valley, box canyon, or near ridge lines before initiating a climb.
Controlled vs. Uncontrolled Airspace
If you’re near Class B or Class C airspace and become lost, communicating early is critical to avoid airspace violations.
Night Flying
Lost procedures at night require special care. Visual references are limited, so relying on climb and communicate steps become even more important.
Avoiding Common Mistakes with the 5 C’s
Let’s walk through how each step of the 5 C’s helps prevent real errors:
- Confess prevents denial and delay, which often leads to worsening the situation.
- Climb avoids low-altitude terrain collisions or out-of-range radio signals.
- Conserve maximizes your fuel endurance while problem-solving.
- Communicate opens the door for assistance, vectors, or emergency handling.
- Comply ensures quick recovery when help is offered.
Many NTSB reports list delayed decision-making or lack of communication as major contributors to preventable incidents. The 5 C’s help counter those behaviors.
