Find an Alternative Landing Time/Location

Break it Down

• Mary’s flight is delayed to arrive on the island.
• Booked landing time will have to change.
• Write deterministic algorithm to find later landing time in Courtenay, or reroute to Smits Field.

First we’ll need to check on the expected arrival time of the flight. This may be a calculated value.
Next we’ll probably want to see a list of available landing times for the user to select if there happens to be one that works.
Alternatively, I’ll give the user a “default” button so they can book the default landing location instead.
Whatever they click on, a list item or the default button, I’d like to book the landing time at the respective destination.

Variables

flight = { // object that describes details about the flight
  destination:"Courtenay", //scheduled destination 
  default:"Smits Field", //default landing strip
  remainingDuration()}; //remaining flight duration
courtenayAvailableArrivalTimes = []; // array of remaining arrival times

Functions

func bookArrival(location, time){
  //book arrival for location, at time
};
func calculateArrivalTime(duration){
  return currentTime() + duration;
};
func displayArrivals(arrivalTime){
  /* display available arrival times from courtenayAvailableArrivalTimes array
  that are no earlier than arrivalTime. display as clickable list items. */
};
func select(slot){
  //break out location & time variables for bookArrival() func
  //use bookArrival() func, send courtenay for loc, time for time
};

Main Script

//calculate ETA using remaining duration of flight
calculateArrivalTime(flight.remainingDuration();

//display available arrival times
displayArrivals(calculatedArrivalTime(flight.remainingDuration()));

//book arrival using value of booking you click on
<li onclick = "select(this.innerText)">{{ date }} {{ time }}</li>

//alternatively, click "default" button to default to Smits Field
<button onclick = 
  "bookArrival("Smits Feild", calculateArrivalTime(remainingDuration()))"
>Default</button>
