How would you navigate if all VOR's and NDB's en route fail?
How would you navigate if all VOR's and NDB's en route fail?
With the IRS/INS/GPS or visually.
What increases Mcrit?
What increases Mcrit?
Swept wings, thin wings.
What’s the temperature at FL150 according to ISA?
What’s the temperature at FL150 according to ISA?
-15°C
because:
-2°C per 1000 feet gives -30°C.
ISA: 15°C at sea level - 30°C = -15°C at FL150
What does a Mach trimmer do?
What does a Mach trimmer do?
A Mach trimmer automatically compensates for Mach tuck above Mcrit.
How are contrails formed?
How are contrails formed?
Their formation is most often triggered by freezing water vapour from the exhaust of aircraft engines.
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.
If you climb to FL300 at a constant IAS of 250kts, what would happen to the TAS?
If you climb to FL300 at a constant IAS of 250kts, what would happen to the TAS?
TAS will increase.
What is an orographic cloud?
What is an orographic cloud?
An orographic cloud is formed as the air rises up the slope and will often envelope the summit.
When the air is humid, some of the moisture will fall on the windward slope and on the summit of the mountain.
What is an aerofoil chord line?
What is an aerofoil chord line?
A straight line conecting the leading edge with the trailing edge of an aerofoil.
What is the height of the tropopause according to ISA?
What is the height of the tropopause according to ISA?
36,090ft in ISA
