I have flown instrument approaches in various aircraft, from small single-engine planes to large commercial jets. I have encountered different types of weather conditions, from clear skies to heavy rain, fog, and snow. I have also flown into different types of airports, from small regional airfields to large international hubs.
Through my experience, I have learned that flying instrument approaches requires a combination of skills, knowledge, and preparation. You need to be able to read and interpret instrument approach charts, communicate effectively with air traffic control, and follow standard operating procedures to ensure a safe and precise landing.
Why You Need to Learn How to Fly Instrument Approaches
Whether you are a student pilot or an experienced aviator, learning how to fly instrument approaches is essential for your safety and the safety of your passengers. It allows you to land in adverse weather conditions or low visibility situations, which can be critical in emergency situations. It also enhances your flying skills and makes you a more confident and competent pilot.
In the next sections, I will guide you through the procedures for safe and precise instrument approaches, including the different types of approaches, the equipment and tools you need, and the techniques for flying them. Let’s get started!
What is an Instrument Approach?
An instrument approach is a set of procedures that pilots follow to safely and precisely land an aircraft in low visibility conditions. Instrument approaches are designed to help pilots navigate through clouds, fog, and other weather conditions that limit visibility. These procedures are crucial for pilots because they allow them to land safely and avoid accidents.
Types of Instrument Approaches
There are several types of instrument approaches that pilots can use depending on the weather conditions and the airport they are landing in. The most common types of instrument approaches include:
- ILS (Instrument Landing System)
- GPS (Global Positioning System) Approach
- VOR (VHF Omni-Directional Range) Approach
- NDB (Non-Directional Beacon) Approach
The type of approach a pilot chooses depends on the equipment available on the aircraft and the airport’s approach capabilities. Each approach has different minimums and requirements that pilots must adhere to for a safe landing.
Why are Instrument Approaches Important?
Instrument approaches are essential for safe and precise landings in low visibility conditions. Without these procedures, pilots would be unable to land in bad weather, which could result in accidents and fatalities. Instrument approaches provide pilots with the necessary tools to navigate through clouds, fog, and other weather conditions that limit visibility.
Instrument approaches also help reduce the workload on pilots, allowing them to focus on flying the aircraft and making critical decisions. These procedures provide pilots with a step-by-step guide on how to safely land the aircraft, reducing the risk of human error and accidents.

Preparing for an Instrument Approach
Before beginning an instrument approach, it is essential to prepare adequately. The following are the critical steps to take:
Flight Planning
Flight planning is crucial to ensure that the pilot has all the necessary information about the flight, including the destination, route, and alternate airports. The pilot should also review the approach charts for the destination airport and any alternate airports. The charts will provide information on the approach procedures, including the minimum safe altitude, missed approach procedures, and any obstacles that may be present.
Weather Briefing
Weather briefing is essential to ensure that the pilot has up-to-date information on the weather conditions along the route and at the destination airport. The pilot should obtain the latest METARs, TAFs, and NOTAMs for the destination and alternate airports. If the weather conditions are below the minimums for the approach, the pilot should consider diverting to an alternate airport.
Equipment Check
Before beginning the approach, the pilot should perform a thorough equipment check. The check should include the navigation and communication equipment, autopilot, and any other essential systems. The pilot should also ensure that the aircraft is properly configured for the approach, including the landing gear, flaps, and speed brakes.
Once the flight planning, weather briefing, and equipment check are complete, the pilot is ready to begin the instrument approach. Remember to stay alert and focused throughout the approach, follow the procedures precisely, and be prepared to execute a missed approach if necessary.
Executing an Instrument Approach
Once you have established communication with the ATC and have received clearance to conduct an instrument approach, it’s time to execute the approach. The following steps will guide you through the process:
1. Initial Approach Fix (IAF)
The IAF is the starting point of an instrument approach. It is the point where you start descending towards the airport. You should ensure that you have the correct frequency and navigation aids set to receive guidance towards the IAF. Once you reach the IAF, you will receive further instructions from the ATC.
2. Descending to Minimum Descent Altitude (MDA)
As you approach the airport, you will need to descend to the MDA. The MDA is the lowest altitude you can descend to before making a decision to land or abort the approach. You should ensure that you are on the correct glide slope and localizer course when descending to the MDA. It’s essential to cross-check the altitude, airspeed, and heading during this phase of the approach.
3. Missed Approach Procedure
If you reach the MDA and do not have sufficient visibility to continue the approach, you should execute the missed approach procedure. The missed approach procedure ensures that you climb safely and avoid obstacles in the vicinity of the airport. It’s essential to follow the missed approach procedure as instructed by the ATC.
Conclusion
Executing an instrument approach requires precision and attention to detail. Following the steps outlined above will help you conduct a safe and precise approach and landing. Remember to communicate effectively with the ATC and follow their instructions for a successful instrument approach.
Factors That Affect Instrument Approaches
Instrument approaches are a critical part of flying, especially during poor weather conditions. There are several factors that can affect instrument approaches, including weather conditions and air traffic control (ATC).
Weather Conditions
Weather conditions are one of the most significant factors that can affect instrument approaches. Pilots must take into consideration the visibility, cloud ceiling, and winds when planning and executing an instrument approach. The type of instrument approach used will depend on these factors.
For example, if the visibility is low, a Category II or III approach may be necessary. These types of approaches require special equipment and training, and pilots must meet specific requirements to execute them safely.
Another factor to consider is the wind. Strong crosswinds can make landing difficult, even with the use of instruments. Pilots must be aware of the wind conditions and select an appropriate runway and approach type.
Air Traffic Control (ATC)
ATC can also affect instrument approaches. Pilots must follow ATC instructions and adhere to specific procedures when approaching an airport. ATC may direct pilots to specific altitudes, headings, or approach types based on traffic flow and weather conditions.
Pilots must also communicate effectively with ATC to ensure a safe approach. If there is a miscommunication or misunderstanding, it can lead to a dangerous situation. Pilots must listen carefully to ATC instructions and ask for clarification if necessary.
Overall, weather conditions and ATC are two significant factors that can affect instrument approaches. Pilots must be aware of these factors and plan accordingly to execute a safe and precise approach and landing.
Conclusion
Instrument approaches are essential for pilots, especially in low visibility conditions. The ability to fly instrument approaches safely and precisely requires a combination of knowledge, skill, and practice. In this article, we have covered the basic procedures for flying instrument approaches, including:
- Choosing the appropriate approach
- Reviewing approach charts
- Programming the avionics system
- Following the approach procedure
- Monitoring altitude, speed, and heading
