Microwave In The Galley?

Sun Feb 07, 2016 7:05 pm

Are there any airlines flying with this fitted as standard in the galley or does it cause problems with Avionics, a friend asked why use convection ovens?
you don't get a second chance to make a first impression!

My first thought is not so much the avionics, but while that could be a contributing factor, I'm thinking more about catering companies storing food in aluminum for heating, which won't work with microwaves.

I don't think it's the frequency (2.45GHz, 0.05GHz more than Wi-Fi on 2.4GHz, which is used for on-board Wi-Fi), but more on the high voltage and high energy hazard. The energy is concentrated and with about 3 megavolts per meter (3×106 V/m), any tin/metal/foil can spark and maybe causing fire easier than convection oven.

BA had a microwave in the Club galley a few years ago. It was very unreliable and did not work very well. I think they have all been removed. Must be all the extra shielding/circuitry for aircraft use

That´s not quite right I'm afraid. A microwave oven is not limited to a single frequency/wavelength, but radiates a wide spectrum of interference all over the 2,4 GHz band (which ranges from 2.402 to 2.482 GHz in Europe and 2.494 in Japan). Any microwave oven will emit interfering signals in the entire 2,4 GHz WiFi band.

BA still has microwaves on all longhaul aircraft although they are hardly ever used. They were launched with great fanfare (and huge expense), their main task to be to heat up hot 'club kitchen' meals requested in between services.

They have been removed from the couple of 'High J' 747's that have been reconfigured to 'super Hi J' config. Also the 787-9 was delivered without them. The longhaul 767's were never fitted with them.

The only thing they ever seem to be used for is to cook the First Class eggs. They do it much better than the regular ovens.

I've seen this model on the 777 Freighter on at least two airlines. Don't recall seeing one on pax aircraft though..

Microwave ovens in airliners are not new.

In 1969 or 1970 when i was a plane crazy kid of ten years, my father who worked in BOAC engineering arranged for me to be shown over one of the company's newest aquisitions, the Boeng 747-136. Three of these monsters (for that time) had been delivered to LHR but sat idle for weeks while the company and the pilots union were in dispute over how much extra the aircrew should be paid for flying them!
That day is still vivid in my memory, when I sat in the left seat of G-AWNB's cockpit, looked around in the avionics bay, had my photo taken sat in the inlet cowl of a JT-9D etc. etc. but the thing that made the most impression on me were the new 'space age' ovens in the galley! It was explaned to me that these new "microwave" ovens cook food from the inside out by "exciting the water molecules" to generate heat, and that if there was not an interlock on the door it would cook your hand from the inside out as well !! This was several years before microwave ovens became a commonplace domestic appliance.

The pic in reply 6 has to be from a freighter galley. All they need is a fridge & microwave for meals. Otherwise with the look of the trash bin it looks like its in a lavatory. lol

A certain "South Pacific Airlines" 747-400 Samuel L Jackson did an emergency landing in LAX a few years ago also seem to have a microwave in the galley. Even has a snake preset button. Got my hint yet? http://www.joblo.com/newsimages1/snake%20microwave.jpg

That pic is indeed from an AA 77W First Class galley. If you look at the glass in the microwave oven door you can see the reflection of two coffee makers and an espresso maker. How many freighters have that?   Just to the left of the microwave, and partially visible, is the door to one of the two convection ovens in that galley as well.

Slightly off topic, but what other home appliances have made it into galleys?

Rice makers (CX, or CA)
Espresso machines ( many airlines)
Sandwich press, toasted (QF)

Any others?

We used to have electric skillets at AA where we'd make eggs and omelettes to order. But that ended a long time ago.

So far then we've seen that some airlines have microwave ovens for:
Crew meals (freighters)
Premium classes for heating meals outside of standard meal times
Cooking eggs for premium class meals

Presumably the bulk advantage that convection ovens have in terms of heating a lot of similar meals at the same time still outweighs the speed advantage that microwaves have, well, that and the continued difficulty microwave oven manufacturers have in getting the same wave distribution evenly across the entire oven, so not all the space inside can be used effectively.

EK have fitted all A380/B77W (unsure of A330/340) J and F Class galleys with (Jamco) Microwaves.

I think TK and OS still have those for the Do & Co onboard chef.

I'm sure they did. It is just an added expense.

Standard galley inserts (ovens, coffee makers) are usually SELL, Driessen, or BE branded. Espresso machines (which use Nespresso capsules) are commonly made by "Iacobucci" (sp). The skillets and rice cooker are offered by Aerolux (www.aerolux.co.uk).

Also not quite right. Newer cheaper microwaves tend to be like that, but they can still build older magnetron types that can concentrate their energy in an extremely narrow band if they want to spend the money.

I can only imagine what the price tag on that thing is.

It's most definitely not your $49 Wal-Mart special, for sure.

Are you sure that photo of the microwave above in in an actual aircraft?? I think not - it's probably taken in a ground training mockup and they simply use a microwave there for speed of heating meals in a training exercise!! Look at all the surround area - it's not an aircraft!

The pictured microwave in this thread is fitted to all Etihad B777 aircraft including the Freighters. Not sure about the Airbus Fleets. We also have toasters which are a nice addition for breakfast.

Slightly off-topic, but why do US carriers have such weird-sized convection ovens (like in the photo above) and who makes them? I have never seen those sizes offered in the Product sections on Driessen, Sell, Zodiac, Jamco web pages.

Well I learned something new today. I had always assumed microwaves couldn't be used in airplanes for the same reason we have to put out phones in flight mode, that they might interfere with the avionics. I figured that was why they used convection ovens. I never knew there were actually a few airlines that do have microwaves.
