Boeing 707 view of wing?
 
I'd be very grateful if someone could advise me on these points.

Could someone advise me if the flight crew can see the wings from the flightdeck? What useful checks for ice could be done visually etc.

G'day Rivets,

From the flight deck you can see the wings and the engines and you could see the effect of nacelle anti/de-ice almost the instant it was turned on.

In over 25 years of flying swept wing jets I've never had the need arise for the use of wing anti/de-icing so I can't help you there.

If you had to conduct a pre-flight wing inspection the best place was from the mid cabin.

Regards,
BH.

Yes, the wings can be seen from the FD, engines also, and there is an ice inspection light available to view any possible wing icing, at night.
Just like the poster above, I haven't used airframe anti-icing either.
Engine anti-ice is used regularly, as needed, however.

707, one tough 'ole bird.

Thanks for that...I was nearing the time of sending a book to the agent, and I suddenly realized that I wasn't totally sure about the extent the flight-deck crew could see back. Seems my visualization was about right. Phew!

This is not the forum for writers, but I wonder if I could PM for a tad more advise on the fire-drill.

B707 engine fire drill.
Silence fire bell.
Throttle closed.
Start lever, cutoff.
Essential power, set as desired.
Transit light, monitor
Fire handle, pull.
If fire light remains illuminated, fire bottle discharge.
wait at least 30 seconds.
If fire light remains illuminated, transfer switch, Transfer.
Second fire bottle, Discharge.

If fire light out (or not), complete the following as time permits:
Fuel shutoff valve, close. (Very important).
Engineers check:
Engine ignition, OFF.
Generator breaker light, check ON.
Check electrical load.
Turbo and bleed, OFF
Cabin altitude and ventilation, Check.
Fuel system, Check Fuel Management as needed.

If fire persists, accelerate to Vmo, gear and flaps, UP
If fire still not extinguished, land ASAP.

Thanks very much 411A, that'll help me breath some life into the emergency.

Poor guy's F/O is blinded by a lightning flash, and #4 engine is all but destroyed. I took the storm sequence and a highly destructive flash, from an experience I had in a Viscount, but I thought I'd promote them to what was a nifty aircraft in the late 60s.

"Check Essential!" A long-gone phrase from old Boeing days.
