Founded in 1943 as Hydro-Aire, Inc., Crane Aerospace & Electronics’ location in Burbank, California made a name for itself by revolutionizing the way antiskid braking was accomplished on commercial and military aircraft. The first Hydro-Aire Mark I antiskid system was fitted on the B-47 military airplane. Hydro-Aire, Inc. was acquired by Crane in 1951 and has been a key part of the business since.

 

Crane Aerospace & Electronics continued to advance the antiskid industry over the years through continuous technology evolution starting from the Mark I in 1947 to our modern day Mark IV and Mark V systems. Today Crane antiskid systems are standard equipment on:

 

• All Boeing airplanes

• All Embraer regional airplanes

• Most Bombardier airplanes

• Most Cessna and Hawker Beechcraft business jets

• Most active military (Western) aircraft

    C-17, C-5, C-130, KC-135, KC-10, F-35, and others

 

Crane Innovation in Brake Control - Technology Evolution

 

Mark 1		Crane introduces:   first antiskid in 1947
Mark II		Crane introduces:    first wheel speed    transducer				Electronics to drive rate sensing Linear four-way pressure control valves to modulate brake pressure Improved brake control efficiency & reliability on all pavement conditions
Mark III		Crane introduces:    first adaptive control				Based on maximum braking under all operating conditions Higher response Hydraulic control valves Improved brake control, smoothness and efficiency Wet and dry runway performance improvement
Mark IV		Crane introduces:    first microprocessor-    based digital system				Improved control algorithms allowed efficiencies >95% under all operating conditions Unigain antiskid valve improved system performance under variable pilot pedal input
Mark V		Crane introduces:    complete brake-by-    wire system				Very high performance digital brake control Latest technology used on B787 (electric brake)
