Ingress Of Usmc Vertical Take Off Aircraft

Sat Mar 18, 2006 10:13 pm

Quiz Time!

In all USMC Vertical Take Off aircraft (AV-8A/C/B, TAV-8B, H-1N-Y, Cobra......) the pilot enters the crew station from the right side of the aircraft.

Even though on almost all US military aircraft (excluding those with cabin doors) the pilot enters from the left. This is true for both tandem and side by side crew stations.

Why?

Hint, there is more that one reason.

Have fun,

Both members in a USMC Cobra are technically pilots but the pilot in command is the one in the rear and they enter from the the starboard side of the aircraft. The co-pilot/gunner enters from the port side. I don't really know why Bell designed it this way but that's just the way it is.


Note: this photo was just a test, the pilot was not actually incapacitated as far as I know.

There are actually both technical and historic reasons for the pilot (versus gunner) ingressing on the right on these aircraft.

In the case of the Harrier it is a link similar to that between Roman Chariots and the Space Shuttle SRBs.

Does this have something to with the width of a horse's @ss?  Smile

The historical part does have to do with horses and their riders. But not relative size of their posteriors...

It's not limited to the USMC, the AH-64 also has pilot and gunner entry from opposite sides as well, though this might be a carryover from the AH-1.

I give up, what's the answer?  Smile

Something to do with the direction in which the Roman Chariots always raced?

OK, times up.

The USMC AV-8B originally being of Brit origin, the integrated boarding ladder is on the righthand side. Why? I once asked a Hawker Engineer that question. He told me its a tie to British Calvery mounting their horses from the righthand side. The Harrier is the only USMC or USN jet aircraft of British origin. It is also the only one that is boarded from the right.

All helicopters with side by side seating have the pilot on the right. This dates back down to early helos which had only one collective stick between the two seats. Since most people are righthanded and prefer to have their dominant hand on the cyclic, the right seat became the pilot seat.

With tandem seating helos, climbing into a crew station over the collective lever is a pain. Therefore ingress on the right is prefered. The forward gunner seat has ingress on the left for canopy structual reasons. If the collective lever is up while ingress/egressing, the gunner just has to take necassary precautions with private parts.

Have fun,
