Somebody should ask ChatGPT….
I did; answer below:
Alright, let's break this down in a simple and easy-to-understand way, because entering a holding pattern might sound complicated at first, but with a step-by-step approach, it can become a lot easier to grasp.
### What Is a Holding Pattern?
A **holding pattern** is basically a "waiting area" in the sky. When airplanes are flying and there's a delay in landing (maybe due to weather or air traffic congestion), air traffic controllers will direct pilots to fly in a holding pattern until they can proceed with their flight. The pattern itself is a series of standard turns that the aircraft makes to stay in one location.
The pattern consists of:
1. **Turns** (usually 180°) to change direction.
2. **Straight legs** between those turns.
3. **Altitude** usually stays the same while in the holding pattern.
A holding pattern looks like a racetrack. The aircraft flies in a circle, and it’s important to know how to enter and navigate this circle.
### How to Enter a Holding Pattern
There are several ways to enter a holding pattern, depending on the direction you're coming from in relation to the holding fix (the point in the sky where the pattern begins). You’ll often hear these referred to as **entries**:
1. **Direct Entry**
2. **Teardrop Entry**
3. **Parallel Entry**
Let’s look at each one.
---
### 1. **Direct Entry**
A **direct entry** is when you're flying straight toward the holding fix (the point you need to fly around), and you're aligned with the first leg of the holding pattern.
**How it works:**
- You’re flying straight into the holding fix, so you’re in perfect alignment with the pattern.
- When you get to the holding fix, you fly straight through it and then start your first turn, which will be 180° to enter the holding pattern.
**In simple terms:** Imagine you’re driving straight toward a roundabout. You just turn left or right to get into it. It's the most straightforward way to enter.
---
### 2. **Teardrop Entry**
A **teardrop entry** is used when you’re arriving at the holding fix at an angle that’s more than 90° off from the pattern, so you can’t just fly straight in.
**How it works:**
- You approach the holding fix at a certain angle, then make a wide turn to the left or right to set yourself up for the first leg of the holding pattern.
- This turn is usually about 30° off of the direction you were initially flying. After you make that turn, you’ll fly straight for a while, and then when you hit the fix again, you’ll turn 180° to enter the pattern.
**In simple terms:** Think of it like you’re making a sharp turn into a roundabout instead of driving straight into it. You "teardrop" into the pattern, hence the name.
---
### 3. **Parallel Entry**
A **parallel entry** happens when you’re approaching the holding fix at an angle but in the opposite direction of the holding pattern, typically about 180° opposite. So instead of going straight in, you’re lined up parallel to the pattern’s first leg.
**How it works:**
- You’ll fly parallel to the holding pattern for a short time, then make a 180° turn to enter the pattern.
- This entry requires you to fly in the opposite direction of the pattern for a short time before entering the holding pattern properly.
**In simple terms:** It’s like driving on a side road next to a roundabout, and then turning to enter the roundabout.

### Step-by-Step Procedure for Entering a Holding Pattern
Here’s a simplified, easy-to-follow approach to entering a holding pattern:
1. **Identify the Holding Fix**: This is the point in the sky where the holding pattern starts. It could be a waypoint, an intersection, or a navigational aid like a VOR (Very High Frequency Omnidirectional Range).
2. **Understand Your Direction**: You need to know where you're coming from in relation to the holding pattern’s first leg. Are you flying straight toward it, coming in at an angle, or flying opposite to it?
3. **Choose the Correct Entry**:
- If you’re aligned with the holding pattern’s first leg, do a **Direct Entry**.
- If you’re coming in at an angle (but not opposite), go with a **Teardrop Entry**.
- If you’re coming in from the opposite direction, choose a **Parallel Entry**.
4. **Fly to the Fix**: As you approach the holding fix, you’ll start slowing down and getting ready for the turn into the pattern.
5. **Make Your Turn**: Once you reach the fix, you’ll make the appropriate turn (usually 180°). Start flying the first leg of the holding pattern.
6. **Fly the Holding Pattern**: After the turn, fly straight until it’s time for the next 180° turn, and continue flying in the pattern.

### A Few Key Things to Keep in Mind:
- **Standard Turns**: In most cases, holding patterns are flown with **right-hand turns** (clockwise). This means you’ll be turning to the right as you go around the pattern. However, some patterns may use left-hand turns.
- **Leg Length**: The length of each "straight leg" in the pattern is usually 1 minute. This means you'll fly straight for one minute before making your next turn. The speed you're flying affects how far you travel in that minute, so slower speeds mean shorter distances covered.
- **Timing**: Holding patterns are timed. The idea is to fly around in a racetrack, and when you pass over the holding fix, you’ll know whether you need to turn sooner or later to maintain the proper timing.
---
### Practice Scenario
Let’s make this real simple with a quick example:
**Scenario:**
You’re flying a plane and air traffic control tells you to enter a holding pattern at a VOR (we'll call it "VOR-X"). The wind is coming from the west, and you’re heading towards VOR-X from the south.
- Because you’re aligned with the first leg of the holding pattern, you can just fly directly to VOR-X and make a 180° turn to the right to enter the pattern.
If you were coming from the east (opposite to the holding pattern), you’d need to fly parallel to the first leg for a short while before turning to enter the pattern.
---
### Summary
- **Holding patterns** are like flying a circle in the sky to wait for permission to land.
- The key to entering a holding pattern is to determine your direction in relation to the pattern and choose the correct **entry procedure**: Direct, Teardrop, or Parallel.
- Practice makes perfect! The more you fly, the more intuitive these entries will become.
