Compass Correction Card

At least for my LS8-18, the feds can get you another way - a compass
is on the Minimum Equipment List. So my glider is required to have a
"magnetic direction indicator". The jury is still out on a correction
card, though...

In the world of Federal Aviation Regulations the compass is called a
"magnetic direction indicator" and the compass correction card is a
"placard". Try a search of all the regulations (www.landings.com) and
try to find one regulation related to the installation of a magnetic
direction indicator in a "glider" or an "aircraft" - I found none!
All the regulatory requirements are specific to airplanes, rotorcraft,
or certain airships.

Anyone who finds one related to gliders please let me know. Otherwise
celebrate your freedom by burning your correction cards.

I doubt it. A compass is on the minimum equipment list *for cloud flying*.

You doubt it?

I direct your attention to page 2-7 of the Dec 2001 LS8-18 Flight
Manual. In Section 2.10 Minimum Equipment List, it states "Magnetic
Compass. Under the following paragraph Additonally for Cloud Flying it
states "Compass".

I doubt I'll receive an apology...

You doubt correctly. Im my flight manual (the original German one), I
read on page 2-11 (not 2-7) (ad hoc translated by me):

Minimal equipment: airspeed indicator, altimeter, thermometer, radio.
(But *no* compass.)

Additional minimal equipment for cloud flying: turn indicator, compass,
vario.

So there's something fishy with your manual. And yes, no apologies.

I have the advantage of reading it in English, no ad hoc translation
required. And yes, it is exactly as I posted above, a compass is on
both the minimum equipment list and on the cloud flying list. Since a
LS1f driver also has a compass on the minimum equipment list, it looks
like the fish is rotting on your side.

A bit harsh, considering the German manual is the one on on which the LS
8 has been type certified. So maybe your FAA has added something to the
requirements, or maybe you're talking about a motorised LS8.

Ah, well, there you're wrong again. The LS8 wasn't FAA type certified
on the German manual, but rather on the English one, according to the
references in the TCDS. The TCDS came about 2 years after my plane was
built, too. The manual I'm quoting refers to the motorless version,
and it definitely has a compass in the MEL.

I don't know the FAA rules, but in JAR (now EASA) country, the
regulation is:

JAR 22.1547 Magnetic direction indicator
Unless the deviation is less than 5° on all headings, the deviation
values for magnetic headings in not more than 30° increments must be
placarded near the magnetic direction indicator.


This of course only counts if the compass is part of the required equipment.

No. That is not what the minimum equipment list means.

Only a government agency could come up with something like this: A
Minimum Equipment List (MEL) is an FAA approved list of instruments that
may be *defective* and still have the aircraft to be considered airworthy.

See section 6.p

I see what you mean, Tony - that FAA definition is indeed perverted!
Two questions for you:

1) A magnetic compass is on the LS8 MEL, which seems to indicate that
you have to physically have a compass in the aircraft. Does AC 91-67
allow you put a placard over a blank hole saying "compass inoperative"
and fly with no compass until the next condition inspection?

2) Under the "Additionally for Cloud Flying" paragraph of the LS8 MEL
a turn and bank indicator is listed. Does AC 91-67 imply that I can
placard a T&B "inoperative" in 1/8" high letters and go look at the
interior of clouds (disregarding for the moment that it isn't legal to
fly a glider in clouds in the US)?
