What is drag?
What is drag?
Drag is the component of the total aerodynamic force parallel to the relative airflow.
Drag is generated by any body placed in a flow and it's composed of friction, form, and pressure drag.
How do you prevent an aircraft reaching Mcrit?
How do you prevent an aircraft reaching Mcrit?
Decreasing speed, by reducing engine power or pitching up.
What is convergency?
What is convergency?
Meridians converge from their maximum distance apart (at the equator) to the poles where they meet.
Great circles are the shortest distance between two points and convergency represents the change in direction experienced between those points.
Describe the take off segments.
Describe the take off segments.
1st segment starts at screen height and finishes at gear retracted.
2nd segment starts when the gear is retracted and finishes when acceleration alt is reached (min. 400ft max 1000ft) speed V2.
3rd segment starts at acceleration alt, minimum 400ft, and finishes when the flaps are retracted.
4th segment starts when the flaps are retracted, MCT is set and finishes at the 1500ft.
What is ACA/H? What ACA/H did you use? Why do we have an ACA/H?
What is ACA/H? What ACA/H did you use? Why do we have an ACA/H?
Asymmetric Committal Altitude/Height is the minimum height needed to establish a positive climb whilst maintaining adequate speed for control and removal of drag during an approach to a landing.
In the Seneca at Oxford we used 200ft AGL. At this altitude when continuing for landing you selected the landing flaps (check clear runway, on speed, on altitude, landing clearance received).
You now are committed to land, single engine G/A with flaps 40 and gear down is not possible in a Seneca.
If you where picking up 10.000 litres of fuel in Newfoundland (cold weather), and 10.000 litres of fuel in Lima, Peru (hot weather), where would you have picked up the most fuel?
If you where picking up 10.000 litres of fuel in Newfoundland (cold weather), and 10.000 litres of fuel in Lima, Peru (hot weather), where would you have picked up the most fuel?
In Newfoundland. With cold weather density increases, therefore you would pick up a higher mass in Newfoundland.
Why is anhedral used instead on some aircraft?
Why is anhedral used instead on some aircraft?
Anhedral:
compensates for the wing sweep improves roll maneuverability
Why don’t you want to fly your Seneca into a thunderstorm?
Why don’t you want to fly your Seneca into a thunderstorm?
Due to the structural damage that may occur in thunderstorms, due to hail, severe turbulence and severe windshear.
Besides that, lightning strikes may cause damage to electrical systems and severe icing may occur.
What is a Mach trimmer?
What is a Mach trimmer?
A Mach trimmer is a system that artificially corrects for Mach tuck.
What uses the most battery power, to transmit or to receive?
What uses the most battery power, to transmit or to receive?
Transmitting uses more power.
