What is Mcrit?
What is Mcrit?
Mcrit is the aircraft’s Mach speed at which the airflow over a wing becomes sonic.
Could a Seneca fly to the South of France without stopping for extra fuel?
Could a Seneca fly to the South of France without stopping for extra fuel?
No
You need to uplift four tonnes of fuel, how many litres would you ask for if the SG is 0.8?
You need to uplift four tonnes of fuel, how many litres would you ask for if the SG is 0.8?
5000 litres
(4 tonnes / 0.8 = 5000 litters)
Where is thrust produced in a gas turbine engine?
Where is thrust produced in a gas turbine engine?
Mostly in the fan, but also from the exhaust nozzle duct.
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 clearance do MSA values give?
What clearance do MSA values give?
They provide at least 1000ft clearance over obstacles within 25NM of the homing facility.
On A high wing anhedral airplane, like a BAE146, and a high wing straight winged aircraft like a Fokker 50, why they don’t have dihedral wings if it has so many advantages?
On A high wing anhedral airplane, like a BAE146, and a high wing straight winged aircraft like a Fokker 50, why they don’t have dihedral wings if it has so many advantages?
A high wing location like the BAE and the Fokker give a natural stable contribution.
This is because the Center of Gravity is underneath the wing, therefore when disturbed the C.G. provides a positive momentum opposite to the distortion.
How can you calculate Vref?
How can you calculate Vref?
Vref = 1.3 x Vs0 (stall speed in the landing configuration).
What is an anti-servo tab?
What is an anti-servo tab?
An anti-servo tab works in the opposite way to a servo tab.
It deploys in the same direction as the control surface, making the movement of the control surface more difficult and requires more force applied to the controls by the pilot.
What is departure?
What is departure?
Departure is an east-west distance along a parallel line of latitude, other than the equator.
Departure is calculated by: Change of longitude(minutes) x cosine of latitude.
