altitudeSpeedEnvelope

Create an altitude flight envelope (H-M diagram) for a Boeing 737 aircraft with an equivalent airspeed (EAS) x-axis.

ax = altitudeSpeedEnvelope(1.6,12500,255,125,80000, ...
   MachLines=[0.2,0.4,0.7,0.88],XAxis="EAS",MachMax=0.8)

ax = 
  Axes (Altitude vs. Airspeed Flight Envelope) with properties:

             XLim: [0 280.5000]
             YLim: [0 15000]
           XScale: 'linear'
           YScale: 'linear'
    GridLineStyle: '-'
         Position: [0.1300 0.1127 0.7750 0.8123]
            Units: 'normalized'

Create three flight envelopes and plot them on tiled axes ax1, ax2, and ax3 using the tiledlayout and nexttile functions.

Create a figure specifying the left, bottom, width, and height positions.

figure('Units','inches','Position',[1,1,12,12]);

Create a 3-row, 1-column, loosely tiled chart layout using tiledlayout.

tiledlayout(3,1);

Set the first tile to ax1 using nexttile, and then create and plot the altitude versus airspeed flight envelope using the altitudeSpeedEnvelope function.

ax1 = nexttile;
altitudeSpeedEnvelope(ax1,1.8,8000,64.3,16.2,1000,MachLines=[0.05,0.1,0.15]);

Set the second tile to ax2 using nexttile and then create and plot the airspeed versus load factor flight envelope using velocityLoadFactorEnvelope.

ax2 = nexttile;
velocityLoadFactorEnvelope(ax2,0,1000,16.2,1.5,64.3,[-1.2,1.8],[-1.5,4],XAxis="EAS");

Set the third tile to ax3 using the nexttile function, and then create and plot the turn rate versus flight speed flight envelope using the turnRateAirspeedEnvelope function.

ax3 = nexttile;
turnRateAirspeedEnvelope(ax3,1.5,16.2,1000,3.8,84);
