Take off after Taxi Issue with the last of 3 Ju52s

[jollyjack]

S! Messing with a tester mission:

 

I programmed an airfield with an Ai taxi-take off. It works OK with three Bf109F4s, nicely start, move to the runway, fly a circle and land, park OK.

However after paring the wing men disappear leaving the leader behind parked on his own.

 

Now when i replace the three Bf109s with three Ju52s, the latter planes start and move to the runway, in a much slower tempo.

Now but only the 2 first ones takeoff and nicely fly the same route, but leave number 3 behind at the start of the runway.

The other two cannot land though, because no3 is blocking the runway.  

 

Checked that waypoint altitudes and speeds were OK for a Ju52 BTW.  Is this some bug?

Try increasing the distance between the last taxi point and the takeoff VPP - particularly for large planes I notice they have issues if these are closer together.

Thanks for the tip, tried various distances, but the 3rd Ju52 seems always stuck at the VPP takeoff point, at the red circle, the first two planes happily fly off:

 

 

Can t be that it has to do with waypoint settings, high, medium or low?

Trains only shoot AA from wagons when set to low priority f.i. PS any idea of a minimum distance?

There is some take-off logic buggery that has crept in recently, so might not be a mission design error.

Ah, meanwhile i gave up ...

Indeed after multiple tests I must admit there are issues. The whole stuff is buggy. 

Even with two JU52 it may happen they stay both stuck. 

My opinion here is that the second or third JU52 never reach the point and orientation so that the takeoff will take place. Sometimes the second does and they takeoff.

The JU52 is very badly maneuverable on the ground. The planes move by small step until they reached their takeoff formation point.

There is a moment where the step is small and the engine power is not enough to make the plane move, so it is not in position and all planes are stuck.

I had this issue in the past with multiple planes taxiing and it would take ages before they takeoff.

Unfortunately the devs will not correct these taxiing issues soon.

 

One way to solve the problem is that after a while you can deactivate the airfield and takeoff command.  Put a CheckZone Trigger with object link to detect the third JU52 when he enters the zone around his final position. When the third Ju52 enters the CheckZone it will trigger a Deactivate command linked to the Takeoff command and the Airfield object.

Then after a few seconds you trigger a new Takeoff Command with the No Taxi parameter checked. In this new situation it similar to planes already on the runway without taxiing. In this case they all takeoff in the directions in which each plane is oriented. It does not work always well but sometimes yes. 

 

One other solution is to separate the whole action in two steps. One is to have them taxi until they arrive on the runway and are more or less in place. Then you delete the three JU52, as well as the command Takeoff. The Leader will have a OnPlaneDestroyed event that will trigger and Activate (not Spawn as you cannot spawn a flight group) a flight of three JU52 that you have properly setup on the runway ready to takeoff and then you will activate their own Takeoff command and all will leave in joy.

 

The JU52 is a little special. With other planes that have more power and are more maneuverable taxi and takeoff is fine. I have a three Pe2 bomber flight with each one carrying one ton worth of bombs and they taxi and position themselves and takeoff without a problem.
