The reason why chocks are preferred over the parking brake, is due to the way parking brakes work on aircraft. On commercial aircraft, the pilots apply the brake manually, then turn on the parking brake, which closes a hydraulic valve trapping the pressurized fluid in the brakes. Due to internal leakage of the valve, the brake pressure will slowly bleed down over a few hours. Therefore, after a few hours the brakes will no longer hold the aircraft. Further, most aircraft ramps are slightly sloped away from the terminal, so the aircraft would end up rolling backwards. Due to the bleed down issues, most airlines require pilots to stay in the cockpit ready to apply brakes until the wheel are chocked.
cool :)
With the Fish and wildlife in charge it would crash in the ocean... You might hurt a goonie landing
Qual o motivo do Pouso?Ai e uma Base Militar,confere?
Sucked worse for the Japanese Navy.
Largely habitated by birds now.
You are correct though, serious history..turning point in the Pacific.
Why do they Block the tires... _doesn't it have a parking brake_
A gust of wind can easily cause this craft to lurch forward or backward. So the chocks help prevent that.
