Pilotage is the art of knowing where you are by reading a map and comparing it with the surrounding terrain and landmarks, while dead reckoning is the art knowing where you currently are by using a compass, your ground speed, a clock and an initial known position.
The methods used in this chapter include pilotage—navigating by reference to visible landmarks, dead reckoning—computations of direction and distance from a known position, and radio navigation—by use of radio aids.
Elapsed Time: The time computed from gate departure time to gate arrival time.
A display on the DME indicates the aircraft's distance from the station in nautical miles (nm) and its groundspeed in knots. VOR/DME systems are limited in range to 141 nautical miles (nm) or 260 kilometers (km). DME can pinpoint aircraft location using the radial and the distance information from a VORTAC.

For the purpose of the present Law, the term “Pilotage”shall mean to pilot vessels to navigate on the channels in ports, coastal waters, inland rivers or lakes.
Actual Elapsed Time and Business Elapsed Time. Actual elapsed time is the total time the SLA has taken until this time, minus any pause duration. Business elapsed time is the total time the SLA has taken until this time, minus any pause duration, within the business schedule used by that SLA's SLA Definition.

flying time in British English (ˈflaɪɪŋ taɪm ) the amount of time taken in flying in an aircraft from one place to another. within 4 hours flying time of the U.K. The flight had a flying time of approximately 15 hours.
The Automatic Direction Finder (ADF) is an aircraft navigation product that automatically calculates the relative bearing of the aircraft to the radio station.
directly over the VOR, the DME would show a distance from the VOR of approximately 2 NM.
The DME avionics in aircraft send a pulse signal to the ground based DME, which responds with an answer pulse signal. The receiver in the aircraft measures the time delay between the sent and received pulses and calculates the slant range distance.
