Calculate going: The tread width is 250 mm so this can be our Going. Calculate total going: Flight 1 â 250 mm = 9 x 250 = 2250 mm plus Flight 2 â 250 mm = 10 x 250 = 2500 mm plus the landing width 900 mm = 5650 mm. Check results with BCA requirements: Rise: 171 mm is within the range of 115 to 190 mm.
You need to know that Foundation Brakes refer to the brakes located at each individual wheel. There are many different types of foundation brakes, but the most common one is the S-Cam drum shown in figure 5-2. For the pre-trip exam, you'll need to know all the parts of an S-Cam brake system shown in that figure.
What Is a Brake Booster? Brake boosters are used only on power brakes, not manual brakes. The booster's function is to give more braking power with minimal pressure on the brake pedal. If the booster is not working properly, you will still have brakes, but the brake pedal will be very hard to push. A brake booster is what gives power brakes their power. It works on vacuum from the engine. The booster pushes on the master cylinder with the pressure applied to the booster by stepping on the brake. If the engine is off, it cannot get vacuum, therefore the brakes will be hard when the engine is off.
