What are the effects on the human body in case of depressurisation?

What are the effects on the human body in case of depressurisation?

Hypoxia, a lack of oxygen to tissues of the body due to low partial pressure at altitude.

Symptoms are: blue lips, apparent personality change, impaired judgement, muscular impairment, short term memory loss, sensory loss, hyperventilation, unconsciousness.

Other possible effects:

  • Baurotrauma

  • Lung damage

Would you be happy if VMCG is higher than V1?

Would you be happy if VMCG is higher than V1?

No, because if your critical engine fails at V1 you have to continue your takeoff roll, but because you’re under VMCG you are unable to maintain directional control.

Why do we use Jeppesen charts/plates?

Why do we use Jeppesen charts/plates?

Jeppesen charts and plates are simplified and uniform.

What is an NDB?

What is an NDB?

Non Directional Beacon, a medium range radio navigation aid that sends out a signal in all directions for an aircraft to home to.

How does an aerofoil work?

How does an aerofoil work?

An aerofoil is a body shaped to produce an aerodynamic reaction (lift) perpendicular to its direction of motion, for a small resistance (drag) force in that plane. It achieves this by accelerating the flow passing over it, and decelerating the flow passing under it. This change in velocity causes a change in pressure, which in turn generates lift.

What is the cabin altitude of the Boeing 737 on a cruise flight level?

What is the cabin altitude of the Boeing 737 on a cruise flight level?

8.000ft

How does an IRS work?

How does an IRS work?

An IRS is an Inertial Reference System  which consists of accelerometers, gyroscopes (laser) and a position computer.

The computer calculates the aircrafts position by direction and velocity sensed by the accelerometers from the initial latitude and longitude input.

An IRS enables the aircraft to fly great circle tracks and to navigate accurately across vast expanses where no ground based navigation aids are available.

What are TORA, TODA, ASDA clearways, stopways, and screen heights?

What are TORA, TODA, ASDA clearways, stopways, and screen heights?

TORA= Takeoff Run Available, the length of runway declared available and suitable for the ground run of an aeroplane taking off.

TODA= Takeoff Distance Available, the length of the take off run available (TORA) plus the length of the clearway, if available.

ASDA= Accelerated Stop Distance Available, the length of the takeoff run plus the length of the stopway, if available.

A clearway is an area beyond the paved runway, free of obstructions and under the control of the airport authorities. The length of the clearway may be included in the length of the takeoff distance available (Take Off Distance Available (TODA)). For example, if a paved runway is 2000 m long and there are 400 m of clearway beyond the end of the runway, the takeoff distance available is 2400 m long.

The stopway is an area beyond the runway which can be used for deceleration in the event of a rejected takeoff.

Screen height: TODR is the distance from the brake release point to the point where the aircraft gains a height of 35 ft above the ground. This 35 ft is what we call the screen height. While 35 ft is the screen height for class A airplanes, it is 50 ft for class B airplanes.

On a wet runway, the screen height is reduced to 15 ft.

Why would someone fly a Rhumb Line track?

Why would someone fly a Rhumb Line track?

  • If no IRS/INS/GPS was available, it’s easier to fly a constant heading (but you will need to apply variation).

  • If flying over short distances (as done during your training) the error introduced by flying a rhumb line is insi
