On October 29th, 2013 a beautiful Cessna 560XL Citation XLS with registration marks D-CVVV took off at the Airport Bern-Belp. During taxi the pilots engaged the reverse thrust to slow down the plane. Why didn't they use the wheel brakes instead? The reverser helps to keep the wheel brakes cool and fully operational when needed. Braking excessively does not only wear out the brakes more quickly but increases the danger of hot wheel brakes. Cooling them down takes plenty of time untill the aircraft is allowed take off again.
