What do airplanes have to guard against reaching Mcrit?

What do airplanes have to guard against reaching Mcrit?

Barber pole on the ASI, flying at a Mach number at altitude and audible warnings.

What is anhedral?

What is anhedral?

anhedral is the downward inclinitation of the wing from the root to the tip.

What is Mcrit?

What is Mcrit?

Mcrit is the aircraft’s Mach speed at which the airflow over a wing becomes sonic.

What is the range of a VOR?

What is the range of a VOR?

VOR stations are fairly short range: the signals are line of sight between transmitter and receiver and are useful for up to 200 miles.

Each station broadcasts a VHF radio composite signal including the navigation signal, station's identifier and voice, if so equipped.

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.

What is the difference between angle of attack and angle of incidence?

What is the difference between angle of attack and angle of incidence?

Angle of attack is the angle between the chord of the aerofoil and the relative airflow.

Angle of incidence is the angle between the chord and the aircrafts longitudinal datum.

Why does a swept wing increase Mcrit?

Why does a swept wing increase Mcrit?

A swept wing makes the velocity vector normal to the leading edge a shorter distance than the chordwise resultant.

Does the N1 compressor produce thrust?

Does the N1 compressor produce thrust?

Yes, with the modern high bypass turbofans the N1 compressor works as a huge propeller, it takes a big mass of air and gives it a relative small acceleration.

Around 70% of the air will bypass the core of the engine, only 30% of air will be compressed further and will eventually go through the combustion chamber.

What does a Mach trimmer do?

What does a Mach trimmer do?

A Mach trimmer automatically compensates for Mach tuck above Mcrit.

What are fusible plugs, where are they used, how do they work, why do we have them?

What are fusible plugs, where are they used, how do they work, why do we have them?

Fusible plugs offer protection from tire blowouts caused by thermal expansion that is generated in the tire under extra hard braking conditions.
