Modern so called "standard equipment" of the airtaxi industry. Everyone who ever used or worked in airtaxi business knows what is a CJ. Opertionally, it is a balance of everything: payload it can carry, range it can fly with it, and price we pay for it. It's a little bit of a compromise for every item mentioned, but it's a very useful and effective compromise. It is a very reliable machine and can fly in almost any weather other than a dense fog (these kind of aircrafts are not equipped with systems allowing landing in severely limited visibility conditions). Cabin is spaceous and modern.

Toilet is available, but preferrably used for so called "emergencies" only...

An airplane which has all the good stuff from modern lineup of light jets like XLS and larger CJs (like 2+) in terms of payload, range and performance. Cessna put best ideas into SII because they were planning next generation jets, they wanted to test things a bit, make sure it works, and it did - almost all ideas worked out. As a result it has very good performance, so range and payload it can take are much better than its cousin C550 Bravo. As the same time it is cheaper than a Bravo in operation, and much cheaper than an XLS or CJ2+.

It's important to understand that aviation industry does not work on a principe "until it lasts" and "we fix it when it's broken", instead all components have scheduled replacement intervals, and with a normally flying aircraft these intervals are just a few years (usually around up to 6-10 years only). So even though you might fly an airframe, which has quite a respectable age, most if not all components on it, including engines, are next to new. Also, all aircrafts undergo upgrades over its life to bring it up to speed for flying in modern airplace, which gets more complex every day.

It can fly in almost any weather excpect dense fog (lights jets are almost never equipped for severely limited visibility landings). Cabin is spaceous and modern, these things get refurbished and renewed. For this one in particular, cabin was refurbished in 2022.

Has a toilet, but it's considered a so called "emergency" use only.

Old, but good. So many hours were flown in this time of aircraft across the world in all possible and impossible conditions over the decades that by now, every convievable and inconcievable problem is known and fixed long time ago (both, operationally and maintenance-wise). So even considering its age, a well maintained Citation I is very safe and reliable. Also, one needs to understand that aviation industry does not work on a principe "until it lasts" and "we fix it when it's broken", instead all components have scheduled replacement intervals, and with a normally flying aircraft these intervals are just a few years (usually around up to 6-10 years only, which is a "baby" age for an aircraft). So even though you might fly an airframe, which has quite a respectable age, most if not all components on it, including engines, are next to new. Also, all aircrafts undergo upgrades over its life to bring it up to speed for flying in modern airplace, which gets more complex every day. Of course, attention is also given to cabin, which gets refurbished, though style and design might seem a bit dated...

Quite capable aircraft like any modern light jet. In terms of operational balance (payload, range, price) it is close to modern CitationJet (CJ), with price being even a bit lower. Safe to fly in almost any weather except dense dog (it's very uncommon for any light jet to be equipped for severely limited visibility landings).

No toilet.

• Model: 
  Cessna C500

This is a workhorse airplane, in a good way, extremely durable and reliable. It can take a decent payload and in terms of weight and volume, and carry it for quite extensive distance, yet it is substantially cheaper than a jet for short to low medium distances. Being a turboprop with good performance, in comparison to piston aircrafts of the same size, it can be safely operated in a very wide range of weather conditions, almost like a jet.

Cabin size, comfort and style is comparable to light jets of the era. Contrary to common belief, it does not have noisy cabin environment. It is comparable is not less than a jet with aft-mounted engines, it's just the sound is a bit different (smooth brrr instead of harsh sssss .

No toilet, though.
