Flying and Skip Bombing the Blenheim on Cockpit Instruments

[Skoshi Tiger]

Hi Jimbop,

Thanks for the new video, Level bombing here I come!

Just one question, I've been playing with my Kane Dead Reconing Computer (a very dangerous thing for a dyslexic person to do!) and was wondering how you came about geting your TAS? What temperature did you use?

Setting it up with a 200mph IAS and a 190 TAS I came to a Outside air temp of about -40 C

(By the way I'm not trolling here just trying to get my head around things )

In my calculations without a thermometer, taking OAT as 9C (15C - 6C due to temperature lapse) and a IAS of 200 I came to a TAS of ~208mph



Cheers and thanks for the video!

I like the look of that toy! To be honest I am only just coming to grips with IAS vs TAS vs GS and simply use the conversion table at the back of the manual. This is adjusted for the temperatures used at in-game altitudes I think.

However, I find that if I actually use GS instead of IAS I end up hitting short of the target. If I just use IAS as on the instrument panel I get my best results. This does not hold true for the HE 111 so I may just be doing it wrong in the Blenheim rather than a game bug. But anyway, I can still hit the target!

A bigger difference seems to be the altitude. Make sure you adjust before takeoff since the pressure seems to vary according to the time of day in-game and you can be a few hundred feet out on startup.

Ha! Standard issue in the Kent St Senior High Aviation course in 1982! (They're propbably still using them!

It really looks like we need Met reports! To work out the GS using vectors you use side 'B' of the computer and a chinagraph pencil!
