747F Cockpit Access

Mon Jan 14, 2008 4:53 pm

I've been onboard many a plane, both as a passenger, and for work. One plane I haven't taken a ride on yet is a 747 freighter, and that is supposed to change next week when I'm going to be flying one to Anchorage, which brings out this stupid question:

How does one get to the cockpit of the plane ? It seems the stairs are at L1, so is there some sort of collapsible stairs that can be pulled up for (un)loading to get up there, or am I going to pull myself up on a rope (ok, kidding, but still) ?

All the ones I have seen have a set of retracting stairs (really a glorified extension ladder) that can fold into the ceiling to allow pallets to pass.

On our aircraft just to the left of the L-1 door there is a fixed ladder.

Enjoy your ride!

Alright, this is going to be interesting. Thanks folks, now all I have to do is hope they do let me in the actual cockpit for some sightseeing, as opposed to sitting behind it, and this should be a fun ride.

(please God don't let me slip on the ladder and look like an idiot)

Don't worry, many other distinguished idiots have walked that path ahead of you.

Climbing up the ladder is easy, it's coming down that is harder!

How do you get out in an emergency? The ladder looks like it can't be lowered when cargo is below it, and freighters don't have the upper level door.

Look again, there is an upper deck slide and a cockpit overhead hatch if needed. In addition, there is no slide on door 1L.

The ladder is retracted when loading/unloading only.

During flight the ladder needs to be extended

Why add complexity and weight. The crew service door/slide and overhead hatch suffice.

What about jamming in case of Emergency?.

What kind of jamming? Structural? There are already 2 exit points on the upper deck. You can what-if it to death. Bottom line is: the 2 exits meet the regulations; anything else adds costs without adequate return.

Exactly.
Are they any stats pointing to the Jamming of either exit available?

If any of the upper deck doors are jamed it's mostly because you've crashed, in that case find the nearest light, that's probably an exit.

Are you saying they never have Locking mechanism issues.

I've been around the B747 for over 20 years and, to tell the truth, have never had mechanical issue with the crew service door or the hatch. Not one. Plenty of issues with the main doors, but they've always seemed overly complicated to me.

I have been flying the 747/1/2/3/SP/400 off and on for over 20 years. I have never heard of any problems with the crew service door or the escape hatch.

According to the MEL, both the escape deck hatch and the crew service door have to be functional. There is no MEL relief.

This def proves the reliability of the Exits on the type.Thanks.
