Mandated manual braking

Ever heard of an operator mandating use of manual braking because medium autobrakes are not enough ?

That sounds like a company blindly using auto-brakes for all landings regardless of whether they are required operationally because of runway length or surface conditions. Yet another case of automation addiction or automation dependence.

There are pilots who, because of company mandated procedures, receive little or no opportunity to keep their hand in at normal use of manual braking and thus become apprehensive if faced with manual braking. Unbelievable to some readers but a fact of life nowadays

Centaurus!
You have hit the nail on the head!
My company mandates the use of auto brakes on every landing regardless of how long the runway is or how heavy/light you are. Drives me nuts!
Landed at a midwest hub one night, and the copilot had never not used auto brakes or reverse. I'm like, hey lets use full flaps, no auto brakes and no reverse, its long and dry. OMG, you could feel the lack of air in the cockpit as it was all sucked up his sphincter.
Afterwards as he relaxed a little, he said something like, " Whats the big deal? We didn't need any brakes until well after 80 knots.
Thats the dumbing down of pilots........ Don't teach them anything except what the company wants to see.

It is not surprising at all. Check the QRH. Maximum manual braking gives you minimum landing distance. Also Landing distance with failure the reference landing distance is with MAX manual braking.

Along those lines, I'm being told it is ilegal if I don't comply with maximum brake deflection on touchdown since the calculation was made with manual braking.
whatever happened to airmanship

If LDA meets the requirement with only manual braking then you will have to. Besides everything is not legal or a SOP. Certain things fall under technique that may give you better judgment or control.

On a previous type manual braking was mandated at certain airfields to ensure performance for tech reasons. Autobrake modulates (on certain types) to give a rate of deceleration so with reverse thrust in use wheel braking is reduced. Manual braking gave us the benefit of wheel and engine retardation at maximum limits if needed.

Correct method for this is to select Autobrake MAX to ensure max. Autobraking from the moment you have whell spin-up. And then brake manually using full reverse and required manual braking force.

It is VITAL on resticted RWY's to brake ASAP after touching down. What you do NOT want to do is press the brakes before touchdown "to ensure immediate braking" . You will in that case destroy your tires, and you are already completely in Landing mode instead of deciding to stop or go when you select reverse.

Difference in decelleration distance between Autobrake MAX and Max Manual during these first couple of seconds is far less than waiting even 2 seconds with starting to brake ( the time to press the brakes to full even costs you more time)

autobrake MAX is not allowed for landing on the 320

Not only you never use MAX autobrake in air, on new air crafts it is not even possible to select it in the air.
