Selecting the Proper Wheel and Brake Combination
The proper wheel and brake combination for your aircraft will provide adequate safety, stopping power, feel, and control.
Some important factors to consider are:

STATIC LOAD RATING — This is the weight on each wheel, at maximum static aircraft weight, that the wheel is capable of supporting. The listed static load rating for each Grove wheel includes the FAA load safety margin for normal operations. If you plan to operate your aircraft in extreme conditions, such as a very rough unpaved strip, you may wish to consider a wheel with a higher static load rating.
  BRAKING TORQUE RATING — This determines the deceleration rate as well as the ability of the brake system to hold the aircraft at static engine run-up. This is a function of the brake system hydraulic pressure and total brake caliper piston area. Too low a value results in poor stopping power and inability to hold the aircraft at static run-up. Too large a value results in overly sensitive brake pedal feel and excessive weight. Our standard wheel and brake sets provide optimum values for most aircraft. If you are using over-sized tires, or if your master cylinders produce lower than normal operating pressure, you should consider a brake caliper with larger piston area.

One of the functions of the brake system is to absorb the heat energy developed during braking.  The majority of this heat is absorbed by the brake disc.  The larger the mass of the disc, the more heat energy it is able to absorb.  A well designed brake system will provide adequate disc mass without excessive weight.  The kinetic energy required to stop an aircraft is a function of the mass (weight) of the aircraft multiplied by the square of its landing speed. Calculate the kinetic energy for your aircraft by entering whole numbers (no comma separators) into this form.

"Begin Braking" Speed: Kts MPH


Kinetic Energy per wheel = ft-lbs.
