Mental Dead Reckoning Flashcards

1
Q

What is drift and how is it measured?

A
  • Drift is the angular difference between the HDG steered by the pilot and the TR of the aircraft over the ground
  • Measured from heading to the track

Q

What is dead reckoning?

A

Dead reckoning is when the position of an aircraft is calculated by:

  • the pilot using a previously known position
  • applying the actual direction and speed of travel in the intervening period since that position

Q

What are the two formulas for estimation of ground speed and time?

A

1) Speed (KTS) = Distance (NM) / Time (HR)

2) Time (HR) = Distance (NM) \ Speed (KTS)

Q

What is the definition of Track made good?

A

The actual path of the aircraft over the ground, this is a function of heading and wind.

17
Q

What is the definition of Track Error (TE)?

A

The angular deviation between the required track and the track made goods. Also referred to as drift.
