What about using water on those hot brakes???

Cargo 360 - Three steel brake Classics in service now with carbon brake -400s to come.
Classics - 30 Flaps, 80% N1 reverse (P&W), and manual brakes applied below 80 knots for 1 hour turns in ANC (without contaminated runways). As someone said earlier, this results in green band temps. Med Autobrakes results in mid-yellow temps. ANC landings are usually at Max LDGWT. No problems with flap tracks (1988 classics with mods). Got to smoothly start reducing reverse as you approach 80 to avoid the dreaded "Scrap & Whitney" compressor stalls! Carbon brakes last longer with autobrake use (one steady application). |
Dragonair
F30 std, F25 may be considered for example, windshear, approaching MLW in gusty winds to avoid flap load relief ref Braking technique our books state: Brakes should preferably NOT be applied until the AC reaches 80Kts or less Autobrake use: MED only when landing on very wet or slippery landings, MAX only when minimum stop distance required. still crews discretion when to use Autobrake MIN Reverse: we have P&W JT9-7R4G2 and use std 70% N1, allowed to use more on short, wet or slippery runways to a max of 87% N1 nominal also allowed to use idle reverse on long dry runways and light weights 521 |
Little bit of the track of the thread but can anyone tell me why 2&4's extend before 1&3's. Seems to me that it should be the other way around to keep the wing tip flying where the aileron is?Some body told me it was something to do with twisting of the wing but I dont know how true that is.
What a great airplane. I miss flying it. The futures bright. The futures orange! |
re the steel brakes on the classic...some figures I keep in the back of my head and I emphasise this is for a max stop on a T/O roll...
MTOW 377.8....... 110 kts Intermediate 330 T ...... 120 kts light 285 T (equates to max ldg wt)..... 130 kts max brake application at these speed / weights and best get a call out to the boys in the little red trucks because the best outcome is a bunch of blown fuse plugs..... the worst is toast ! Hope this is of some help FW |
747 classic landing flaps.
BA classics PAX 25 the norm landing flap setting and auto brakes min.
Dragonair classics Freighters norm landing flap setting 30 manual brakes. Both airlines autobrake med used engine out landing or limiting runway. Good luck with the interview!;). |
