What are the lines on a fighter jet canopy?

It is an explosive cord which helps to crack the canopy (pdf!) before the ejection seat has to do this all by itself. When ejection is commanded, the harness is tightened and the canopy is shattered, and only then the real ejection starts.

Why fighter jets fly upside down?

However, airplanes that consistently have to fly upside down (like stunt planes or fighter aircraft), have symmetrical wings. Therefore, they can’t rely on the shape of the wings; they only manage to fly upside down by tilting their wings in the right direction to generate sufficient lift.

Do German fighter jets have pressurized cockpits?

$\\begingroup$Historical perspective: Many German fighters of WW II had pressurized cockpits. For example, the models of the Me-109 Gending on an even number had a pressurized cockpit, while the odd-numbered ones had an unpressurized cockpit.$\\endgroup$ – Peter Kämpf Feb 19 ’16 at 15:15 2 $\\begingroup$Yes to cool the electronics.$\\endgroup$

What are the main problems with modern fighter jets?

Transmissibility of the combiner and windshield are another problem. The thick windshields of modern fighters, placed at fairly acute angles, transmit only about 60 per cent of the light passing through them.

Why are fighter jets so expensive to make?

The kind of cutting edge technology that enables a fighter jet to fly and produce so much firepower at the same time cannot be produced at a lesser cost. Every fighter jet is made of state-of-the-art tech and state-of-the-art tech costs money.

How does cabin pressure change in a fighter jet?

Cabin pressure in a passenger airplane will increase (almost in a linear fashion) as the airplane climbs. However, fighters keep ambient air pressure to a certain altitude. It maintains this pressure until a certain pressure differential is met, and then cabin altitude increases to maintain this differential.
