[REPORTED]Planes piling up at airbases

Check this out please.

APC operations are not efficient / bugged.

Check the following image. These planes are awaiting take-off.

3 planes are circling the base for landing. No other planes are in the air around the airbase.

These planes are flying in a continuous circle, and aren't landing.

I have run this for about half an hour. The circling planes don't land, and the planes awaiting takefoff don't take-off.

Deadlock!

And the queue is growing at the airport. Still no plane landed after 15 minutes!

Now this is interesting. One of the planes circling to land, got out of fuel and crashed. And now the other planes are landing!

This after ... 45 minutes?

Now all of the circling planes have landed, and still no take-off from the awaiting planes.

It sure gives some nice scenery.

But it is a bit dissapointing that these planes don't take-off!

Is this something worth to have a look at by ED please?

Sv.

Yes I have this from time to time. Somehow the queue gets out of order and they deadlock. Until a fighter comes along and shoots one and they fix themselves! :)

But seriously, from a code level, you can see that, no1 to land, is unable, yet no2, IS ABLE?! How is that possible? Must have been a "once only check" that was invalid then remains that way. Would appreciate a loop to keep checking for landing that didn't stop.

Am I the only one confused why the profile picture of you both says "MOOSE"?

They're part of the Mission Object Oriented Scripting Environment group.

Amazed to find that hardly anybody reacts. Isn't a sim about takeoff and landing???

And that excludes BIGNEWY ... , who is kind to help out.

You'll get a demo mission soon.

Yes please post a mission file of it occurring. Sometimes we can recreate bugs based on screenshots or what a person said in a post, but not always. A mission file or track is still most appreciated, especially if the AI behavior is reliable within the mission itself. I can spend a day plopping down all the aircraft I want on my own and still won't be able to get the AI to be stuck in a loop like that. Observe dumb landing behavior, sure, but stuck in a loop or other similar bugs is not guaranteed.

I will do a series of tests in 1.5.7 and 2.1.

APC-001: Airbase Takeoff and Landing test: Spawn 10 airplanes every 3 minutes. Observe time until landing, Taxi before takeoff, Takeoff, Landing holding, Taxi after landing, CPU efficiency and add Comments if any.

APC-002: Airbase Takeoff Stress Test: Spawn 10 airplanes after 10 seconds. Observe any Taxiing locks, or airplanes removal. Observe CPU efficiency.

APC-003: Airbase Landing test after Damage: Spawn 10 airplanes every 3 minutes. Attack some airborne airplanes. Observe landing and comment.

APC-004: Airbase Landing test out of fuel: Spawn 10 airplanes low on fuel every 3 minutes. Observe landing and comment.

APC-005: Airbase Landing test with 4 airplanes per group: Spawn 5 groups of 4 airplanes at the airbase. Observe takeoff and landing.

APC-006: Airbase Takeoff and Landing test with different airplane types: Observe takeoff and landing.

A result table will be shown explaining the results and things to look out for while resimulating.

And I will upload the test missions accordingly.

If required, I will add detailed descriptions of some of the findings in separate posts.

I am not an APC expert, but will document according my personal findings and interpretations.

If I make a mistake or have interpreted something wrong, pls verbose but don't shoot the messenger :-)

I am using MOOSE for the tests, as it helps me to dynamically spawn and do other stuff to support the tests. This test is not about the scripting engine, but about APC operations, so thought it is okay to do such.

Test results of test scenario APC-001: Airbase Takeoff and Landing test: Spawn 10 airplanes every 3 minutes.

Overall: Overall test results.

Time: Total time in hours:minutes until all planes landed. --:-- is shown if not all planes could land (or takeoff).

Taxi Takeoff: Obervation of taxi behaviour and efficiency (speed, lockups, removal of planes).

Takeoff: Observation of takeoff efficiency.

Landing Hold: Observation of planes airborne while awaiting landing confirmation from airbase.

Taxi Landing: Observation of taxi behaviour and efficiency after landing. (speed, lockups, removal of planes).

CPU: Direction of time accelleration possible during test. The more time accellerated possible, the more efficient the CPU utilization is of the airbase APC.

Comments: Any other comment that documents the test.

Legend: ++ = perfect, + = good, - = remarks -- = failure with remarks.
