DH82A - Pilot notes

[stiknruda]

Do any of you good folk have the pilot notes for a Tiger Moth in soft format?

I've not flown one for some time but have been asked to deliver one next week and a quick refresher before I see the baby, on the numbers, slat operation, etc., would be invaluable.

Thanks in advance

Hi Stik,

Sorry I can't help with the pilot notes in soft format. In fact the only notes I have seen have been the ones produced by the Australian Air Force.

However, since I fly Tiger Moths as my day job, I can give you the numbers:

Caution: Don't necessarily believe the instruments !

Warm up: min 4 minutes at 800-1000rpm
mag check: 1600rpm, max drop 100 rpm
trim: taxi = full back
t/o = slightly forward of middle
cruise= as required
land = usually around middle
Climb: 60 KIAS, max rpm 2100 rpm (30min) Vx 55 KIAS
Cruise: 1950 - 2050 rpm
Stall: 39 KIAS
VNE: 139 KIAS
Approach: 60KIAS, over hedge at 50 KIAS min
X-wind: 8 knots grass unless current, 2 knots tarmac unless fitted with brakes.
X-winds best handled by wheel landings
Shut-down: 1 minute at 800 rpm

Finally, if you are ferrying an unfamiliar a/c, don't bother with the slats. They only reduce the stall by a couple of knots and I keep them locked in unless I know the aircraft.

Hope this helps, and don't forget the left rudder during the take-off roll!

I have a paper set and am in Bungay - pm me if you want to borrow

Hi Stik.

As Legalapproach, I also have good notes.
If you're in the W London area, PM me and I'll get them to you.

Having said that, the info from QNH is quite adequate - just keep the feet going and choose grass if you have the choice.
If the Wx stays like this, it will be a super trip. Enjoy !

Rgds, Sleeve.

Thanks everyone - QNH's numbers are just what I needed.

Legal - Bungay is 5 miles away, check PM's.

Further to QNH's notes - Don't forget to retard the throttle after T.O., easily forgotten but gives you carb. ice protection:ok:

Thanks everyone.

XL714 arrived safely at her new home last night after a 45 minute ferry flight on a gin clear evening. It was the first time in almost 5 years that she'd left the ground but the entire trip was without incident or worry.

The TNS's arrived last week from dH Supprt and I envisage a very busy next few weeks bringing her up to the condition where I will be happy to sell her with a new 3 year CofA. My engineer is crawling all over her currently!

Nice Tiger :ok:

Anyone complied with TNS 40 yet and have they done it in situ ?

We are going to try do ours next month.

Check the TNS - it tells you to do the inspection in-situ. You only need to remove the wires if they fail because of corrosion or cracking. Make certain that the wires are correctly tensioned and then do a test flight to make sure that they do not vibrate in flight. I am told that it takes about a day to do the whole job including the test flight, provided that all the wires pass the inspection.

Had a long chat with dHSL then S McK about this yesterday. The TNS only applies to non polished s/s wires.

My wires are mild steel so will be removed in pairs for cleaning, inspection then painting (etch primer and a two pack). I won't spray the threads but will paint them in on assembly as witness marks.

The cost of a replacement set including end forks and clevis pins in polished s/s was a tad under two k plus the vodka and tonic.

Just to correct a minor error in your last ..

TNS 40 applies to ALL variants of stainless steel - polished or not, it does not matter.

You are correct to say that TNS 40 does not apply to streamline wires made from carbon steel.

A similar TNS is in course of issue for application to the de Havilland biplane twins - Dragon, Dragonfly and Dragon Rapide. The CAA is about to 'consult' before making this mandatory also.

The mandate for TNS 40 on the single-engined Moths looks like it will be published in CAP 747 at the end of this month.

Looks very tidy !

How do you get it in your hangar ? - sideways on the skates ?

By the way - the other Pushpak is at Priory Farm now ! (1 year too late for a formation photo)

cheers

Thanks for the info,

Tha chap I help hadn't fully read the TNS and his info was a little vague. I read it last night and it does seem straight forward. One good thing is that his wires were brand new 20 years ago and have been oiled from day one.

Interesting. In this month's Pilot, in the "Fly Like a Pro" feature, one of the contributors reckons that throttling back on take-off (he references a Chipmunk) could lead to overheating as there isn't the extra gasoline sloshing around in the cyliders.

[foxmoth]

Chippie is different - it has a carb heat lever (though the RAF wire locked it in hot). The dH82a has a flap that gives cold air on full throttle but when the throttle is retarded (about 1/2") gives hot air. I have not seen this months Pilot, but suspect this is a more general reference.

[High Wing Drifter]

Foxmoth,

Many thanks for the clarification. The contributors point was "know your engine". I just wondered if the Chippie and Tiger would have similar issues.

My mate's just bought a Tiger ... problem is, we've just built a hangar .... and now have to raise the roof 6" :\
