What is the maximum real life speed that the landing flaps could be deployed?

Were the landing flaps ever used in combat?

Did the RAF or RAAF at Darwin ever have Vc models with the Volkes tropical filter?<div class="ev_tpc_signature">

All the Spit Vcs issued to Australia were equipped with that godawful ugly Volkes filter, AFAIK. Same with the CBI.

The nicer streamlined Aboukir and derivative filters were local mods developed in the Med, and I'm guessing that with the increased availibility of MK VIII/IX type Spits, no move to replace the clunky old Volkes was made.

The only ones who liked the aesthetically challenged, performance sapping POS Volkes filter were the mechanics who worked on the (surviving) aircraft equipped with them and Axis aircrewmen in N. Africa who didn't see real Spitfire performance until the MK IXs started trickling in.

The manual has a maximum speed limitation of 160 mph I.A.S for both the Flaps and the undercarriage.

Don't know about using them in combat, but Section 2, paragraph 19 states:
"19. Flying at reduced airspeeds
In conditions of bad visibility near the ground, reduce speed to about 120 mph I.A.S. and lower the flaps. The radiator shutter must be opened to keep the temperature at about 100 degrees C and the propeller speed control should be set to give cruising r.p.m."

The only reference I can see to combat is:
"For combat manoeuvres climbing r.p.m. should be used."

Now, In Pilot's notes general:
"The speed limits on the lowering of flaps and undercarriage arise from calculations either of the strength of the parts to withstand the air forces or of the power of the operating mechanism. It should be noted that the figures quoted are limits based on such considerations, and not handling speeds recommended as the best speeds at which to perform these operations."

That sounds like it's saying best use a lower speed than the limit, but the landing checklist in the Pilot's notes gives 160 m.p.h. as the speed at which to drop the flaps...

So, flaps used at no greater speed than 160 m.p.h. then ?

Then again,
"In combat and in emergencies pilots must take risks with their aircraft, balancing one risk against another; limitations must be strictly observed only in so far as there is no sufficient reason to exceed them."

There you go. The choice is yours as long as you can justify your decision to your superiors...<div class="ev_tpc_signature">

I would also like to know if Spitfires ever used their flaps in combat, they are used a lot in this game by online pilots.

In game: The flap limitations are found on a plaque next to the flaps lever (Mk Vc here) --
