Now before I get this topic started, I know I will get some backlash from some of you about how this will decrease the realism of IF. This will actually increase the realism of Infinite Flight. (In my opinion)
So, as many of you may have noticed, there are a lot of large airports that are not class B or C. Some are class D. Currently in Infinite Flight, class Delta airports have an aircraft restriction set on them; the restriction does not allow the user to fly the B757 & A321 or bigger into those airports.
But there are many examples of airports where planes as large as the AN-225 fly and are capable of handling large aircraft. Here are some examples from my home state of Ohio. (I’m using Ohio because I am most familiar with it.)
Rickenbacker International (KLCK)
KLCK is a class D airport that is part of the new and ever growing Rickenbacker Inland Port. It has two 12,000 feet runways. Currently, the Airport recieves regular service from the airlines below:
(The Image excludes Kalitta, Ethiopian Cargo, FedEx, UPS, DHL, Castle Aviation, & AirNet)
The aircraft flown on the routes above range from B777 to B747. Rickenbacker also handles any charter traffic that KCMH cannot properly handle (usually B767s and bigger). The airport has also hosted the AN-225 many times. The Ohio Air National Guard’s fleet of KC-135 tankers are based also at KLCK.
Wright-Patterson Air Force Base (KFFO)
KFFO is one of the most infamous airbases of the US Air Force and yet most people do not realize that it is class D. Currently, the aircraft flown there most often are C-17s, C-5 Galaxy, B747, and various other smaller planes
Airborne Airpark - Wilmington (KILN)
KILN is the former home of Airborne Express, DHL USA, & Amazon Prime Air. It is now a maintenance base for ABX Air. As you might expect, Airborne Airpark has handled aircraft all the way up to B747s. The airport has one 10,000+ foot runway and another 9,000 foot runway.
Basically, my point is that removing the class D restrictions after global would increase the realism of IF by a large margin. This wouldn’t affect those who fly passenger jets as much as it does those who fly cargo and military aircraft. Many cargo airports and air force bases are class D.
Thanks for taking time to read my suggestion! I hope I explained everything clearly.
