What is operating mass in aviation?

Operating Mass (OM): It is the DOM plus takeoff fuel but without traffic load. It can be thought of as Wet Operating Mass as opposed to DOM. Traffic Load: It is the total mass of passengers, baggage and cargo, including any ‘non-revenue’ load (like spare parts etc).

What is the dry operating mass of an aircraft?

Dry Operating Mass (DOM) is the total mass of the aeroplane ready for a specific type of operation excluding usable fuel and traffic load. The mass includes items such as: i) Crew and crew baggage. ii) Catering and removable passenger service equipment.

What is regulated landing mass?

Regulated Landing Mass (RLM) is the lowest of the ‘performance limited’ and ‘structural limited’ landing mass. Regulated Take-Off Mass (RTOM) is the lowest of the ‘performance limited’ and ‘structural limited’ TOM.

What is included in dry operating weight?

DRY OPERATING MASS The dry operating mass includes: (a) crew and crew baggage; (b) catering and removable passenger service equipment; and (c) tank water and lavatory chemicals. (2) standard masses, including hand baggage, of 85 kg for flight crew/technical crew members and 75 kg for cabin crew members.

What is aircraft mass and performance?

MASS (WEIGHT) & BALANCE. Predicting Performance. The Forces on an Airplane. Four Main Forces Lift, Weight, Thrust, and Drag. Flying Further Than Any Other Aircraft in History.

What is mass balance aircraft?

In addition, because aircraft control surfaces are mounted on flexible structures like wings, they are prone to oscillate (“flutter”), a dangerous effect which can be cured by bringing the centre of gravity (c.g.) of the control surface to the hinge line. This is called mass balancing.

What are the four forces that act on an aircraft?

It flies because of four forces. These same four forces help an airplane fly. The four forces are lift, thrust, drag, and weight.

What gives an airplane forward force?

Thrust: The force that moves a plane forward through the air. Thrust is created by a propeller or a jet engine. An aircraft in straight and level flight is acted upon by four forces: lift, gravity, thrust, and drag. The opposing forces balance each other; lift equals gravity and thrust equals drag.

What is aircraft structure?

Most airplane structures include a fuselage, wings, an empennage, landing gear, and a powerplant. Fuselage. The fuselage is the central body of an airplane and is designed to accommodate the crew, passengers, and cargo. It also provides the structural connection for the wings and tail assembly.

What is basic operating weight?

Basic Operating Weight (BOW) Total weight of the aircraft, including crew, ready for flight, but without payload or fuel (sometimes excludes the crew). Includes all fixed ballast, unusable fuel, normal operating level of oil and total quantity of hydraulic fluid (transport aircraft only).

What is trip fuel?

The Trip fuel is the required fuel quantity from brake release on takeoff at the departure aerodrome to the landing touchdown at the destination aerodrome. This quantity includes the fuel required for: Takeoff. Climb to cruise level. Flight in level cruise including any planned step climb or step descent.

What is drag and lift?

Lift is defined as the component of the aerodynamic force that is perpendicular to the flow direction, and drag is the component that is parallel to the flow direction.
