# IAN landing — part 1

> IAN landing — part 1: conditions, actions and checks for the Boeing 737-800.

Use this procedure when its prerequisites apply. Confirm each required aircraft state before acknowledging the corresponding checklist item.

## General

Use this procedure only for the selected IAN-capable configuration and assigned approach. Glide path alive and glide path capture are separate conditions. Verify the applicable active and armed modes.

The checklist's lateral verification is **Localizer capture**. The EFB IAN description distinguishes FAC/G/P from ILS VOR/LOC/G/S. Apply an explicit interpretation for the selected IAN procedure. Do not force an ILS mode solely to match the checklist wording.

The checklist ends with flap selection and missed-approach-altitude setting at glide-path capture. Use the assigned landing-continuation procedure for the remaining landing.

### 1. APP roll mode — **Arm**

Arm APP for the selected approach. Verify the applicable armed and active flight-mode indications.

> **Checks and evidence**
>
> **Expected response:** Arm
>
> **Verification:** Verify arming separately from later lateral/vertical capture.

### 2. Localizer capture — **Verify**

Verify the source’s lateral-capture requirement using active mode and signal/approach evidence, without treating APP arming as capture.

> **Checks and evidence**
>
> **Expected response:** Verify
>
> **Verification:** Require the valid active capture state for the approved approach interpretation.

### 3. At glide path alive: Landing gear lever — **Down**

**Condition:** At glide path alive.

When the stated condition is satisfied, select the landing gear lever DOWN. Verify the required lever position and gear indications.

> **Checks and evidence**
>
> **When:** At glide path alive.
>
> **Expected response:** Down
>
> **Verification:** For DOWN, verify the required safe indications; for UP/OFF, require actual lever and gear-state evidence appropriate to that command.

### 4. At glide path alive: Landing gear indicator — **3 green**

**Condition:** At glide path alive.

Observe three independent green/safe gear indications.

> **Checks and evidence**
>
> **When:** At glide path alive.
>
> **Expected response:** 3 green
>
> **Verification:** Require valid safe indications for nose, left and right gear using the applicable lamp decoding.

### 5. At glide path alive: Flap lever — **15**

**Condition:** At glide path alive.

When the stated condition is satisfied, select 15. Verify the required lever detent and actual flap/slat configuration.

> **Checks and evidence**
>
> **When:** At glide path alive.
>
> **Expected response:** 15
>
> **Verification:** Verify the chosen lever detent and the required actual flap/slat configuration.

### 6. At glide path alive: Engine start switches — **Cont**

**Condition:** At glide path alive.

Select both engine start switches CONT. Verify both rotary-switch positions. These switches are separate from the fuel/start levers.

> **Checks and evidence**
>
> **When:** At glide path alive.
>
> **Expected response:** CONT
>
> **Verification:** Require both applicable rotary-switch states.

### 7. At glide path alive: Speedbrake lever — **Arm**

**Condition:** At glide path alive.

Set the speedbrake lever to ARM. Use the applicable lever-detent conversion and verify the required position.

> **Checks and evidence**
>
> **When:** At glide path alive.
>
> **Expected response:** Arm
>
> **Verification:** Confirm the required lever detent and, for ARM, the separate SPEEDBRAKE ARMED indication.

### 8. At glide path alive: SPEEDBRAKE ARMED indicator — **Illuminate**

**Condition:** At glide path alive.

Verify the distinct SPEEDBRAKE ARMED annunciator is illuminated after the arming step.

> **Checks and evidence**
>
> **When:** At glide path alive.
>
> **Expected response:** Illuminate
>
> **Verification:** Require the actual ARMED lamp, not merely a lever/control ratio.
