Can also be used for technical reasons...For instance, the Hunter FGA9s of 208 Squadron based at Nairobi's Embakazi airport in 1960 were obliged to use the chute for every landing. This was because the landing TAS was rather high due to the 5800 feet airfield elevation and the runway was very smooth. The combination of these two things led to excessive maxaretting from the wheel brakes and this jumping up and down of the brake pressure led to excessive main undercarriage "leg walking" with increased wear...So, we had to use the chute for all landings at base, to prevent this extra wear.
