What is the critical point?
What is the critical point?
The critical point (CP) is a point on a track where it is as quick to go on as it is to turn back.
Also known as ETP (Equal Time Point) and PET (Point of Equal Time).
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.
What is windshear?
What is windshear?
Windshear is a change of wind speed and/or direction from place to place, including updraughts and down draughts.
It is ussualy characterized by a strong change over a short distance. Windshear can effect the flight path and airspeed and can be hazardous.
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 in a go-around, which take-off stages will still apply?
If in a go-around, which take-off stages will still apply?
None. The go around procedure is distinct from the take off procedure. You will still have an acceleration altitude, but you will not have a screen height, V1, Vr, V2, flap retraction altitude, etc.
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
What wings does the Boeing 737-800 use?
What wings does the Boeing 737-800 use?
Swept back wings
What is a wing tip?
What is a wing tip?
A wing tip is the part of the wing that is the most distant from the fuselage of a fixed-wing aircraft.
How much thrust comes from the N1 fan?
How much thrust comes from the N1 fan?
Depends on the engine.
In the case of the 737-800 CFM56, 27,300lbs total thrust at a ratio of 5.5:1
What does a bypass ratio of 11:1 mean?
What does a bypass ratio of 11:1 mean?
For every 1kg of air passing through the combustion chamber, 11kg of air pass bypass the combustion chamber.
