Turbo lag

Feels good :pilotfly:

Not if you forget to lock the tailwheel on takeoff (been there, done that, written off one plane after groundlooping out of control when the turbo kicked in :D).

Should take-off not be done without the boost lever aft?

Take off MP is 52" but you need, turbocharger to get this boost, so throttle and boost level should be locked together.

Ah, good to know. I have been doing it wrong then so far.

I only started using the turbo lever above a certain altitute when manifold pressure starts dropping.

Takeoff tutorial mission suggests 48" but you still need turbo for that.

 

On the other hand, with standard fuel load and clean config, blower-only power is sufficient, nothing wrong about that. On YT vids of restored "Wicked Wabbit" being flown it seems mr Shoffner doesn't use more than 42" anyway.

Most of p-47 restored, don't have turbo operational any way.

But for combat take off this mean full ammo, fuel, bombs rockets etc. Max take off power will be just simply safer, especially when operating from gravel airfields with limited runway lenght.

I always use full power for take off, it is just much more fun.

Depends on the ambient temperature greatly.

Can you elaborate, what exactly depends on ambient temp?

Max MP for take off ??

Turbo usage on take off, its in the real world manuals.

Probably not a factor in ETO but pacific for sure :thumbup:

Did the same. Became an instant mental checklist item I will NEVER forget.

You can use the booster attached to the throttle most of the time. Takeoff, landings, cruise, etc.

 

The only time I've found I don't need/use the booster is when doing ground attack. By taking off throttle to dive and attack and then throttling up to climb again, for me it is best to not have the booster on, because the engine can suddenly go from 47" to 64" when the booster kicks in.

 

But that's it. Otherwise, it's always on.
