All approaches should be stabilized by 1000 feet above airport elevation in IMC and by 500 feet above airport elevation in VMC. An approach is considered stabilized when all of the following criteria are met:

- The airplane is on the correct flight path

- Only small changes in heading / pitch are required to maintain the correct flight path

- Speed is not more than VREF + 20 knots IAS and not less than VREF

- The airplane is in the correct landing configuration

- Sink rate is not greater than 1000 fpm. If an approach requires a sink rate greater than 1000 fpm, a special briefing should be conducted

- Power setting should be appropriate for the airplane configuration

- All briefings and checklists have been conducted

Specific type of approaches are stabilized if they also fulfill the following:

- ILS approaches should be flown within one dot of the glide slope and localizer or within the expanded localizer scale (as installed)

- During a circling approach wings should be level on final when the airplane reaches 300 feet above airport elevation

An approach that becomes unstabilized below 1000 feet above airport elevation in IMC or below 500 feet above airport elevation in VMC requires an immediate go-around.

At 100 feet HAT for all visual approaches, the airplane should be positioned so that the flight deck is within, and tracking to remain within, the lateral confines of the runway edges extended. As the airplane crosses the threshold, it should be:

- Stabilized on target airspeed to within + 10 knots until arresting descent rate at flare

- On a stabilized flight path using normal maneuvering

- Positioned to make a normal landing in the touchdown zone (first 3000 feet or first third of the runway, whichever is less)

Initiate a go-around if the above criteria cannot be maintained.
