How to get the aircraft location from a flight path plot?

I have the below data (dummy data) of a aircraft flight path, with the time, latitude. longitude and heading of the aircraft in a table.
The actual data consists of more than 100k rows, and file is too big to be uploaded.
Based on the actual data, I am able to plot the flight path on a map. The flight path map has an x-axis of Longitude and y-axis of Latitude. Problem is if I want to know the location of the aircraft at a particular time (say at 7220sec), how can I get the latitude, longitude and heading of the aircraft from the plot?

% Generate some data
t = (7020:210:10080)';
lon = 102.915 - t/10080;
lat = 1.363 - t/20000;
heading = 153 + t/50040;
% Create an interpolant
F = griddedInterpolant(t, [lon lat heading]);
t = 8024;
F(t) % lat lon heading

load data
whos
%T = table(t, lat, lon, heading)
% Create an interpolant
F = griddedInterpolant(t, [lon lat heading]);
tq = 8024;
F(tq) % lat lon heading
% If you have problem with griddedInterpolant on older version MATLAB
% you can try the following
z = interp1(t, [lon lat heading], tq)
