Check-Six Forums

An investigator reviewing flight data found that as the turn subjected Davis to six times the force of gravity, a temporary decrease in blood flow to his brain likely caused him to experience tunnel vision and become disoriented, the report found.
However, Davis worked to regain control of the plane, "and in the last few seconds he may have been aware of his low altitude and was attempting to save the aircraft," said the report by Marine Lt. Col. Javier J. Ball.
"Kevin had performed these maneuvers in training and in the fleet. He had done them in similar situations and he had a history of performing them well without any problems," Hanzlik said
The Pensacola-based Blue Angels fly without the G-suits that most fighter pilots wear to avoid blacking out during such maneuvers. The suits inflate and deflate air bladders around the lower body to force blood to the brain and heart.
However, the air bladders can cause a pilot to bump the control stick, so the Blue Angels instead learn to manage the forces by tensing their abdominal muscles.
The crash at Marine Corps Air Station Beaufort was the Blue Angels' first since 1999 and the 26th fatality in the team's 60-year history.
Because of the crash, the Navy has increased its exercise requirements for Blue Angels pilots with an additional focus on abdominal muscles. The team has also stepped up its requirements for centrifuge training tailored for Blue Angels pilots.

tanmamba a écrit :Mais sur un Hornet, je n'emploierais pas le terme ''mini manche latéral'', déjà qu'il se trouve au milieu et qu'il a l'air encombrant (par rapport au manche d'un F-16) lollol

JulietBravo a écrit :En fait je ne parlais pas vraiment du Hornet !
Je voulais dire justement que sur les avions à mini-manche latéral il n'y avait pas ce problème que rencontrent les pilotes des Blue Angels !!!
Peut-être que je me suis mal exprimé...

- pour le pantalon anti-G je ne sais pas (on n'a pas trop le temps de voir quand les jambes passent devant la caméra...

Pour le pilotage sans anti-G, les BA ont un pilotage spécifique qui les amène à poser l'avant-bras sur la cuisse

Pour le pilotage sans anti-G, les BA ont un pilotage spécifique qui les amène à poser l'avant-bras sur la cuisse, méthode retenue pour caler le manche et tenir les formations.
Dans ces situations, l'anti-G entraîne un mouvement du manche, ce qui pose problème quand sa sensibilité est réglée à son maximum.

jojo a écrit :Il faudrait un vrai pilote de pointu pour être certain, mais à priori c'est la méthode standard pour piloter avec un manche classique. Les Voltige Victor (2 Mirage F1) volaient en formation très serrée, avec groin et anti-G. Bref ça sens un peu l'esbrouf leur truc.

Why don’t the pilots wear G-suits?
G-suits are designed with air bladders (pockets) that inflate and deflate to keep a pilot’s blood from pooling in the pilots’ legs while executing sharp, unpredicted combat maneuvers. Unlike combat flying, the Blue Angels demonstration pilots know the maneuvers they will fly prior to execution, so each pilot knows when one will be pulling heavy gravitational forces. Anticipating the changes in gravitational forces allows the Blue Angels demonstration pilots to combat the G-forces with muscle contractions. In addition, the Boeing F/A-18’s control stick is mounted between the pilot’s legs. The Blue Angels have a spring tensioned with 35 pounds of pressure installed on the control stick that gives the pilot a “false feel.” This allows the pilot minimal room for uncommanded movement. The pilots rest their right arms on their thighs for support and stability while flying. Therefore, inflating and deflating air bladders in a G-suit would interrupt this support and stability, causing uncommanded aircraft movement. In this case, G-suits would detrimentally impact flight safety.
