Speed reduction due to rear view mirror missing?

[Holtzauge]

A ballpark estimate for the Spitfire Mk5:

 

Cd0=0.0218 and wing area 242 sqft gives flat plate drag area 5.28 sqft or 0.490 sqm.

 

Assume rear view mirror 15x8 cm or 0.012 sqm.

 

Using the v1**3 x Cdo1=v2**3 x Cd02 equivalency:

 

Taking the Merlin 45 +9 boost speed at SL of 480 Km/h as base:

 

480**3 x 0.49= v**3 x 0.502

 

Gives v = 476 km/h

 

So a speed loss of 4 Km/h

 

This is just a ballpark estimate but maybe someone has seen a measured or calculated value in a report? Anyway, right now it says speed loss 0 Km/h under “Unlocks” which seems a bit optimistic.....

I think it's just info missing in the game, if you look at the forums, Han gives a speed loss of 2km/h.

OK, I see it now. Thanks!
