Unlawful Interference, Emergency Landing, Ditching, and Fuel Jettison (Video Notes)

A set of vocabulary-style flashcards covering key terms and procedures related to unlawful interference, emergency landings, ditching, and fuel jettison as presented in the notes.

Unlawful Interference

A security concern in commercial civil aviation. If deviation from the intended track occurs, the aircraft should be flown on the intended track until ATC is informed; if deviation is unavoidable, the commander must broadcast warnings on international distress frequencies; use of the transponder is required; if no procedures exist, proceed at a level 500 ft away from the normal IFR cruising level when vertical separation is 1000 ft.

Intended Track

The flight path the aircraft is meant to follow as planned before informing ATC.

ATC (Air Traffic Control)

The authority responsible for coordinating aircraft movements and providing information and instructions to maintain safe separation.

Transponder

Onboard equipment used to identify and communicate aircraft data to ATC and radar.

IFR Cruising Level

The standard instrument flight rules cruising altitude used for planning and flight as reference for separation.

Vertical Separation

The vertical distance between aircraft; in the notes, specified as 1000 ft.

Distress Frequencies

International emergency radio frequencies used to broadcast warnings when needed.

Emergency Landing

A landing conducted when it is not safe to continue normal flight; aims to minimize risk and preserve the airframe; decision should be timely; may involve landing on unprepared land or sea; landing gear down for landings, gear up for water.

Emergency Landing on Land

For an emergency landing on land, the landing gear should be down.

Emergency Landing on Water

For an emergency landing on water, the landing gear must be up.

Unprepared Landing/Sea

Landing on unprepared land or sea during an emergency.

Ditching

Deliberate landing of an aircraft on water; success depends on level of preparedness and rapid rescue; passengers should brace, wear life jackets, and ensure exits are clear; cabin crew supervision is essential.

Brace Positions

Passenger or crew positions designed to protect occupants during impact in water ditching scenarios.

Emergency Exits Cleared

Cabin crew responsibilities include ensuring all emergency exits are clear for rapid evacuation in a ditching scenario.

Ditching: Responsibilities of Cabin Crew

Cabin crew supervise passenger safety, maintain exits’ accessibility, and facilitate orderly evacuation during ditching.

Ditching: Ditching Checklist

A procedural list pilots use to prepare and execute a water ditching, including speed/configuration and post-impact actions.

Landing Direction Relative to Waves

During ditching, land the aircraft along the direction of the waves to reduce impact forces.

Lowest Possible Speed with Gear Up

During ditching, land at the lowest safe speed while keeping the landing gear retracted.

Tail Touches First

During ditching, attitude should be such that the tail touches the water first to reduce damage.

Do Not Stall; Land the Aircraft

Avoid stalling and ensure a controlled landing to maximize survivability during ditching.

Effects of Ditching

High pitch g forces; nose tends to dig into water; rapid deceleration; aircraft may come to rest quickly.

Fuel Jettison

Controlled dumping of fuel to reduce aircraft mass in an emergency.

Decision to Jettison

The decision rests with the aircraft commander alone.

Jettison Location

Should be conducted clear of cities or towns, preferably over water.

Minimum Altitude for Jettison

The level should not be less than 6000 ft during jettison.

Flaps and Jettison

If the use of flaps adversely affects jettison, their use must be prohibited during the jettison.

No Smoking Sign during Jettison

No smoking sign must be illuminated during the jettison procedure.

Duration of Jettison

The jettison procedure must be completed within 15 minutes.
