Autoland / Approach Mode Documentation

Autoland/Approach Mode is a new feature that was added in August 2015 starting with the Boeing 737-700BBJ bonus plane. Additional aircraft with this feature follow: 

  • Airbus A318, A319, A320, A321
  • Boeing 777-200, 777-200LR, 777-300ER
  • Boeing 787-8, 787-9, 787-10

We will gradually roll it over to other airplanes.

Just like in real life, systems have limitations, the autoland system in Infinite Flight isn't design to magically get the airplane to the runway in any circumstances. The system has limitations and things to know about. This article outlines the most important ones.

- Limitations:
- 15 kts crosswind
- 30 kts headwinds
- 5 kts tail wind
- Interception course with Localizer 45 degrees max
- Landing configuration set 5NM out (final approach speed, gear down, full flaps, spoilers ARM, no changes past 5NM)
- 200 kts max speed during entire approach
- Spoilers in ARM mode
- No de-crabing is done by the system, pilot is responsible for alignment upon touchdown
- Designed for full stop landings only
- Terrain avoidance is the pilot's responsibility
- Standard ILS Approaches only (3 degrees slope max. Will not work at EGLC for example)

Difference between ILS and GPS:
ILS Approaches are extracted from real life data. If you are on a red approach, there's a guarantee that there will be no collision with terrain throughout the approach
GPS Approaches are not extracted from real life and are simply a projection of the runway centerline to create a "fake" localizer with a glideslope set for a 3 degrees descent. This of course does not guarantee that you will not hit terrain during the approach.

Tips:
Airplane has trouble stabilizing: 
- Adjust approach speed (recommended 130 kts for 737/BBJ with full flaps at 25% load)
- Check winds
- We recommend to lock the approach you want prior to engaging the Approach mode
