What is TMG
Track made good
Is the actual path aircraft tracing over the ground
TE
Track error
Angle between TMG and FPT
What is the actual path the aircraft tracing over the ground?
TMG
What is the angle between TMG and FPT
TE
What is the angle between TMG and heading
Drift
What is drift
Angle between TMG and heading
The formula to find TE
(dX60) / D
d= Distance off track
D= Distance travelled
What are the 3 factors affecting drift?
- Strength of wind
- Direction relative to the HDG
- The TAS of aircraft
Do faster aircraft have bigger or smaller angle of drift compared to slow
Smaller angle
What is CASA reccomded buffer to staying in steps of airspace
500 feet above lower limit
What does OCTA mean
Outside control airspace
Flying at a boundary layer between OCTA and a controlled step
What airspace u flying in
The least restricting one
min thickness of transition layer?
1,000ft
What is dead reckoning navigation?
When u certain of present position, certain where you started, know direction, and distance travelled since then
What type of navigation is map to ground
USed DR positons or estimating what you expect to see further down FPT.
Ground to Map
Used when uncertain of position
Scan ground for features
- lost or low level
Use Big to Small, Natural to Man made
