Do Airliners Have Microwave Ovens?

Mon Nov 12, 2007 8:51 am

A friend of mine was wondering. I was like "ehm....? I have no clue, but I know a place..."

Well, they exist... but seemingly more for executive aircraft.

So the regular ovens are convection ovens then?

Even if my MD11F would've a microwave oven, I wouldn't use it because I blew up 2 microwaves already  stirthepot

Since they work with several trays, convection would seem to me the only practical method.

All the ovens I have seen are convection ovens. Remember all the meals are covered with aluminum foil and that does not work well in a microwave.

Almost all ovens on airplanes are convection ovens.

Some planes are equipped with microwave ovens. However they are not the same power as typical microwave ovens, so you'll likely blow something up if you put it in there and it isn't designed for that specific microwave oven.
If you have never designed an airplane part before, let the real designers do the work!

I was told that SQ does have a small microwave for its First Class galley on the 744. And that it was ludicrously expensive Big grin

I'm sure there was a story a while back about BA cabin crew receiving a memo as some of then kept using ovens to reheat meals bought from the supermarket which were not designed for the power output of a/c ovens resulting in damage to equipment. I can't remember if it was referring to a standard oven or a microwave.

Exploding curry costs BA £20,000 by Hannah Summers. Monday, 21 May 2007 British Airways has banned staff from using microwaves for non-airline food after an exploding curry cost the company £20, 000 in damages.

Well I'll tell you that the Falcon 50 my previous employer had a microwave, according our purchasing people it was as stated above ridiculously expensive. It was a GE Spacemaker microwave that had been TSO'd by another company.

For what it's worth.

Used mainly in some Exec jets.The non metallic containers are another reason too.

Good money to be made certifying common off the shelf appliances.

I'll sure a certain airline customer of B/E must have been impressed when they saw how little the same rice cooker sold for at Costco. If memory serves me right it was about 10 percent of the certified component price.

As are many things over in GA land. Your 1968 Cessna 172 loose an alternator? Go down to the auto parts store and get a replacement Motorcraft 1965 Ford Mustang alternator  Wink However, it will lack the FAA PMA approval, although it will be much cheaper than the PMA'd version...

I've also seen that early O-470 powered birds with 12-volt electrical systems (like late 1960's Cessna 182's) use the same starter as Chrysler Hemi engines from the same era...  Smile

I'm sure the same extends to components such as fuel tank sending units, lighter plug sockets, etc. etc.

On the A320 I fly, we have steam ovens, that are convection ovens with added steam to stop the food from drying out. I assume this is fairly standard.

LOL ... it appears some think the reason that microwaves aren't used is just because the meals are covered in metal foil  Smile

Perhaps that's because they're NOT being used in microwave ovens, but convection ovens. I'm going out on a limb here (!), but I assume it would be an easy task to put the meals in non-metallic trays if we decided to use microwaves. I don't think the deciding factor on whether to use microwaves or not, was because the meals were in metal trays.

As others has mentioned, I believe size has something to do with it. Never seen a big microwave with multiple shelves ... although I'm sure they exist. Another reason may be the way that a microwave cooks.. you can pretty much put a tray of any food in a convection oven for x minutes, and it'll get hot/warm, and you can turn it down and keep stuff warm. A microwave is a different matter ... put it on for one minute and some stuff will be boiling and other stuff cold ... a less foolproof method IMO.

BUT ... I'm sure they do have them on some aircraft, because I read somewhere about a "microwave landing system" ... and I understand GE was definitely involved in the technology ... so perhaps that DOES use the GE Spacemaker  Wink

But that would render the Aircraft Unairworthy.

True  Smile
But I guess what most are pointing out is as long as meals are packed in metal foils they cant be used with a microwave.If the trend of Microwave use on Aircraft catches up,The changing over to non metallic containers is not a big job.

BA has fitted one microwave oven in its latest refit of the long haul fleet.
It is not used for regular meals.
It is used for warm between meal snacks that are available in business class.

That's why I said it with a wink  Wink IIRC, the only technical difference between the straight automotive alternator from my example above and Cessna's PMA'd alternator is that the PMA'd version has passed an extra inspection, and had a Cessna part number label glued over the Motorcraft title cast into the alternator housing. I am in no way condoning replacing parts with non-airworthy replacements...

Even the voltage regulator was a Ford part

But it is not legal, it could be exactly the same alternator, but if the alternator does not have PMA approval, an STC or Cessna approval, it cannot be used.

Quoting HAWK21M (Reply 23):

If you are using any non certified part, then your aircraft is not in compliance with its type certificate and technically it falls into the experimental category with all its limitations, but it is not un-airworthy

That’s what STC’s are for, if someone wants to go through the costs of certifying the part, then you could use the automotive alternator by purchasing the STC, either with the alternator or just the STC paperwork itself. That’s how autogas got certified, someone went through the certifying procedure and in most cases all you have to do is buy a piece of paper to be legal.

In my A&P days working on light aircraft, on occasion we would get in an airplane for an annual with some homemade or other non certified item on it. We would tell the owner we could not do the annual because it was not in compliance with the type certificate.

I have seen airplanes with a short wave radio installed, an additional battery in the baggage compartment added without proper venting, car stereo’s hardwired into the electrical system with no circuit protection, airplanes re-carpeted with carpet from the local carpet store and seats re-upholstered by a local boat shop, with material not certified for use on aircraft, just to name a few things owners have done to their airplanes
