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.
Hydraulic disc brakes are the most commonly used form of brake for motor vehicles but the principles of a disc brake are applicable to almost any rotating shaft. Compared to drum brakes, disc brakes offer better stopping performance because the disc is more readily cooled. As a consequence discs are less prone to the brake fade caused when brake components overheat. Disc brakes also recover more quickly from immersion (wet brakes are less effective than dry ones).
