  2. Air navigation - Wikipedia

    en.wikipedia.org/wiki/Air_navigation

    The variation that applies locally is also shown on the flight map. Once the pilot has calculated the actual headings required, the next step is to calculate the flight times for each leg. This is necessary to perform accurate dead reckoning. The pilot also needs to take into account the slower initial airspeed during climb to calculate the ...

  3. Top of climb - Wikipedia

    en.wikipedia.org/wiki/Top_of_climb

    Top of climb. In aviation, the top of climb, also referred to as the TOC or T/C, is the computed transition from the climb phase of a flight to the cruise phase, the point at which the planned climb to cruise altitude is completed. The top of climb is usually calculated by an on-board flight management system and is designed to provide the most ...

    en.wikipedia.org/wiki/Flight_planning

    A Tarom Boeing 737-300 and United Airlines Boeing 777-200 taxiing to depart London Heathrow Airport. Flight planning is the process of producing a flight plan to describe a proposed aircraft flight. It involves two safety-critical aspects: fuel calculation, to ensure that the aircraft can safely reach the destination, and compliance with air ...

  5. Flight length - Wikipedia

    en.wikipedia.org/wiki/Flight_length

    Flight length. In aviation, the flight length or flight distance refers to the distance of a flight. Aircraft do not necessarily follow the great-circle distance, but may opt for a longer route due to weather, traffic, to utilise a jet stream, or to refuel. Commercial flights are often categorized into long-, medium- or short-haul by commercial ...

  6. Slide rule - Wikipedia

    en.wikipedia.org/wiki/Slide_rule

    Slide rule. Typical ten-inch (25 cm) student slide rule (Pickett N902-T simplex trig) A slide rule is a hand -operated mechanical calculator consisting of slidable rulers for evaluating mathematical operations such as multiplication, division, exponents, roots, logarithms, and trigonometry.

  7. Top of descent - Wikipedia

    en.wikipedia.org/wiki/Top_of_descent

    In aviation, the top of descent, also referred to as the TOD or T/D, is the computed transition from the cruise phase of a flight to the descent phase, or the point at which the planned descent to final approach altitude is initiated. The top of descent is usually calculated by an on-board flight management system, and is designed to provide ...

  8. Rate of climb - Wikipedia

    en.wikipedia.org/wiki/Rate_of_climb

    Rate of climb. In aeronautics, the rate of climb (RoC) is an aircraft's vertical speed, that is the positive or negative rate of altitude change with respect to time. [1] In most ICAO member countries, even in otherwise metric countries, this is usually expressed in feet per minute (ft/min); elsewhere, it is commonly expressed in metres per ...

  9. Standard rate turn - Wikipedia

    en.wikipedia.org/wiki/Standard_rate_turn

    Aircraft maneuvering is referenced to a standard rate turn, [1] also known as a rate one turn (ROT). A standard rate turn is defined as a 3° per second turn, which completes a 360° turn in 2 minutes. This is known as a 2-minute turn, or rate one (180°/min). Fast airplanes, or aircraft on certain precision approaches, use a half standard rate ...
