FO103 Flashcards
What is the velocity vector?
Where the aircraft is going. It is roughly approximated with the nose of the aircraft.
What is the lift vector?
The force used to make the aircraft turn. Its position is straight out the top of the canopy.
How do you control placement of the velocity vector? What about lift vector?
Velocity vector with flight controls.
Lift vector with ailerons.
How do you change the magnitude if the velocity vector? Lift vector?
Airspeed for the velocity vector
Elevator/changing G forces for lift vector
What is angle off?
The angle between number 1’s heading and number 2’s heading. Also called heading crossing angle (HCA)
What is aspect angle?
Angle between the longitudinal axis of number 1 to number 2. Its expressed in degrees in multiples of 10.
What is the 3/9 line?
Line extending out aircraft’s lateral axis (wingtip to wingtip). Number 2 must remain behind this line during maneuvering.
What’s turning circle?
Arc you’re flying as you turn where center is the center of the turning circle.
What is lead pursuit?
Placing your velocity vector in front of number 1
What is pure pursuit?
Placing your velocity vector in number 1
What is lag pursuit?
Placing your velocity vector behind number 1.
What makes pursuit curve relationships valid?
Must be on same side of turning circle as number 1.
What are the effects of lead, pure and lag pursuit with number 1 in a turn?
- Lead +aspect angle, +closure, -angle off
- Pure + closure only
- Lag -aspect angle, -closure, +angle off
What is line of sight?
Line from eyes to target.
What is line of sight rate?
How quickly line of sight is moving. It’s associated with movement in direction of canopy.
What is a pitchout?
A turn by both aircraft of approximately 180 deg using approximately 60 deg bank.
