In need of lightweights!
 
Helicopter Examiners for PPL that is.

Does anyone have contact details for sub 11 stone examiners in the south east of England who fly R22's?

Difficult one I know, but needs must! (Either that or the student goes on the slimfast for 3 weeks)

I can't help - but it does make me wonder about the payload.

I thought the R22 had a seat weight limit of 200lbs (or is it 225?).

If it can't carry sufficient fuel for an hour flight plus reserves, an examiner of greater than 11 stone (154lbs), and a candidate who must be below 201lbs (or 226lbs) by definition, then what can it do?

What's the fuel burn? Simple piston and no time to Google I would guess at 7US galls per hour - so...

7 x 6lbs = 42
3.5 x 6lbs = 21

candidate 226
examiner 154

443lbs

Can't it do that?

Have you tried elite at goodwood?
They look pretty small.

I found time - so Googled.

MTOW of 1370, basic empty 830, therefore payload 540.

Seat max weight limit appears to be 240 per side - 480 assuming both max weight.

60lbs for fuel - that's 10 US gallons at point of raising collective, not engine start.

Suggests 8gph at 70% - so navex to refuel and G/H on way back?

Just make it with a 17 stone examiner. That should work, no?

Sadly it's longitudinal CofG which is where our examiner problem lies.

With a BEW 885 (830 sounds like a pipe dream in a Beta II!) at approx 103.4"
A combined crew of 400lbs at 78"
A main tank at 106.8"
An aux at 103.8"

Well, pretend you have no fuel to start with...

91509lbin
31200lbin

An arm of 95.49".

The forward arm limit at 1275 is 95.5". This proceeds backward to about 96.5" at MAUW 1370, in line with a normal fuel line, so irrespective of fuel added, you cannot now restore longitudinal CofG.

Note some of my numbers may be slightly off due to it being morning and me doing it from memory, but they tell the basic story.

We have a Beta I that has a BEW arm of 104.9, however it has no instrumentation in it at all, so he still can't get a pass!

I will try Elite, thanks for the idea.

Or Helicopter Services at Wycombe. I can't imagine either Leon or Ruth exceed the limit you require :ok:

I think Exo went to HS - Ruth is apparently 8 stone - under 1/2 what I weigh :)
