I found a printable and interesting guide on how to visually differentiate between military aircraft. It was published in 2006, and is used by the Army. [Download PDF]
Airliner Spotter offers a huge array of pictures at many different angles, intended for those who intend on differentiating between commercial aircraft.
Hope this helps.
You're looking for a Visual Aircraft Recognition Guide. One example of this is Army Field Manual 3-01.80 (shared by FAS org among others). Not all the photographs are from exactly the same angles but there's lots of diagrams from plan-view angles.
You may also be interested in Aircraft Recognition Guide's characteristic-based search, though it doesn't ...
It's really hard to tell from this photo but an August 2019 photo shows a Changhe Z-18 for a similar sea trial.
Wikipedia indicates PLAN Shandong only carries Z-18 and Z-9 but in this picture it seems too big to be a Z-9.
Can't say for sure, but the size and shape (as far as can be determined from the picture) seems to match the Aerospatiale Super Frelon, which is built under license in China and is in use with the Chinese navy for shipboard operations under designation Z-8.
The image is of poor enough quality that a more precise determination isn't feasible, but the size ...
I have a better candidate than the Mi-17MD now: what I think is the next version after that, the Mi-17V-5. The feature that really prompted the question was the heater not being in the place I'm used to; the V5s have an enlarged right-side door, and that apparently necessitates moving the heater to the top-right position (from where the KO-50 used to be, ...
An ADS-B receiver is the best way to identify an aircraft flying overhead, in most cases. This can be built from about $50 USD, but may be more.
Put simply, you would need
A USB SDR receiver
A computer to connect the reciever to, and run software on
Decoding software (at a minimum, dump1090

That is a Panvia Tornado operated by the UK Royal Air Force.
You can tell by the shape of the nose wheel door, and the rear of it has a characteristic boxy shape with the stabilators lower than the wing. The roundel is the RAF low visibility roundel.
Panavia Tornado, Royal Air Force (UK), 13 Squadron.
The aircraft in the question is identified as belonging to No. 13 Squadron by the distinctive green, yellow and black 'Squadron flash' painted on the aircraft side below the front part of the cockpit.

Going by probability it's likely a KC-130 as there are quite a few of those in the world. The recognition feature would be that it has four teardrop pieces of underwing gear with the external fuel tanks inboard and the drogue refuelling systems on the outboard. There are no other obvious lumps or bumps in the picture to indicate other mission equipment such ...
