Integral Airstairs

Mon Feb 02, 2009 9:45 pm

I have a few questions about integral airstairs?
1. Can the Airbus 320 series be equipped with them? I've never seen one with them, but they would certainly be useful.
2. I seem to remember hearing that some airline (SY?) removed some from 737s. I want to know if a 737 built without them can be retrofitted with an integral airstair.
3. Are any widebodies other than the VC-25s and Il-86s equipped with them on the lower deck? Can they be retrofitted and are any of the VIP 747s going to get them?
Why do Aerospace Engineering students have to turn things in on time?

They were an option on the L-1011.

If they were going to be so useful surely they would be a factory option? Airstairs (esp on the 737) are pretty complex when you see them folding in/out. An A320 is a fair bit higher than the 737 so I'm guessing an even more complicated system would be req to get them in?

In the UK WW has definitely removed them, saving 177kg (http://www.b737.org.uk/history.htm). I'm sure there'll be others. Not sure about retrofitting them; I'm guessing it'd be more money/hassle than its worth for the airline.

Most operators seem to cope fine without them!

I forgot that the Airbii are higher than the 737. Most airlines dont need them for sure, but I was thinking that they would be useful for many charter airlines that fly to smaller airports or use FBOs on a regular basis, not to mention planes in VIP/corporate shuttle service.

I'd say any aircraft probably could get an STC for airstairs if someone was willing to throw enough cash at it...

If one is considering load penalties seriously & fuel economy....between 150-200kgs of weight saved is a big deal.

Ryanair appear to have forward airstairs on their 737-800s, probably because they serve many airports with minimal ground support equipment, or they don't want to pay to use it.

I've done lots of mods removing them, but don't recall ever adding them.

On B737s,there are two systems of operations,The Auto has a lot of sequencing switches & safety locks,The Standby is with the sequencing switches.These switches can be a problem if one does not work.
