IAN landing — part 1

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: ArmVerification: 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: VerifyVerification: 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: DownVerification: 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 greenVerification: 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: 15Verification: 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: CONTVerification: 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: ArmVerification: 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: IlluminateVerification: Require the actual ARMED lamp, not merely a lever/control ratio.
