What is Vs?

Stall speed is defined as the minimum steady flight speed at which the airplane is controllable.

If you have a fire from the engine in the Warrior, what do you do?

If you have a fire from the engine in the Warrior, what do you do?

On the Warrior, I would perform the following items:

throttle closed mixture closed fuel selector off fuel pump off magnetos off (mayday + 7700 if time permits) and check if fire is out heater defrost off batt alt switches off top door latch unlatch seat belts erect secure and make a forced landing

Can you explain what a coastal breeze is?

Can you explain what a coastal breeze is?

A coastal breeze is a wind from the sea that develops over land near coasts.

It is formed by increasing temperature differences between the land and water; these create a pressure minimum over the land due to its relative warmth, and forces higher pressure, cooler air from the sea to move inland.

Generally, air temperature gets cooler relative to nearby locations as one moves closer to a large body of water.

Explain the definition “critical engine”.

Explain the definition “critical engine”.

The critical engine of a multi-engine, fixed-wing propeller-driven aircraft is the one whose failure would result in the most adverse effects on the aircraft's handling and performance.

Due to the asymmetric blade effect (P-factor), the right-hand engine typically develops its resultant thrust vector at a greater lateral distance from the aircraft's C.G. than the left-hand engine.

The failure of the left-hand engine will result in a larger yaw effect via the operating right-hand engine, rather than vice-versa, and it is termed the Critical Engine. Since the operating right-hand engine produces a stronger yaw moment, the pilot will need to use larger control deflections in order to maintain aircraft control. Thus, the failure of the critical (left-hand) engine is less desirable than failure of the right-hand engine.

The operating right-hand engine will produce a more severe yaw towards the dead engine, thus making the failure of the left-hand engine critical.

TAS will increase.

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

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 is a high bypass ratio engine?

What is a high bypass ratio engine?

In a high bypass design, the vast majority of the thrust is derived from the ducted fan, rather than from combustion gases expanding in a nozzle.

A high bypass ratio provides a lower thrust specific fuel consumption (grams/sec fuel per unit of thrust in kN using SI units), especially at zero velocity (at takeoff) and at the cruise speed of most commercial jet aircraft.

Some wings, flaps and rudders are indented, why?

Some wings, flaps and rudders are indented, why?

To increase the strength of the surfaces.

The same strategy is employed by plastic water bottles, by adding ridges to a surface you increase it's structural rigidity
