At Cambrai Covers we go to great lengths to ensure that your cover fits your aircraft perfectly, so it is vital that any Aerials, Probes, Pitot Tubes and Grab Handles on your aircraft have the proper allowances made for them.

The back of our order form shows a plan view of an aircraft. Use this for marking the positions of aerials and probes.

• We will need to know the positions of anything mounted to the upper exterior of the aircraft.
• We do not need to know about anything mounted on the underside.
• If you run out of space please use a plain piece of paper to sketch a diagram - it does not have to be brilliant, as it is the dimensions that are important!

Make all measurements from our datum points:

• Top Edge of the Windscreen (TEW/s) - where the Perspex windscreen meets the metal frame
• The centreline of the aircraft (C/L)
• If a sliding canopy is fitted we use the canopy opening line in the same way as TEW/s.

1. Measure the Outside Air Temperature Probe (OAT) position. If the probe is in the windscreen

2. Measure the positions of the VHF aerials. These are measured back from the TEW/s and left or right of the aircraft centreline. For an example <click here>

PLEASE NOTE:

• Make EACH measurement from the Top Edge of the Windscreen - not from aerial to aerial please!
• Measure from the aircraft Centreline to the centreline of the aerial base.
• Measure the length of the base and note the type of aerial.

3. Measure the position of the GPS aerial.

PLEASE NOTE:This type of aerial is not always fitted. If it is underneath the aircraft just note this on the order form.

• Measure back from the TEW/s to the FRONT of the aerial.
• Measure from the aircraft centreline to the centreline of the aerial.
• Make a note on the form to indicate whether this is a "Flat" or "Shark Fin" type aerial.

4. Measure the position of the ADF aerial.

PLEASE NOTE:This type of aerial is not always fitted. If it is underneath the aircraft just note this on the order form.

• Measure back from the TEW/s to the centre of the mounting post.
• Measure from the aircraft Centreline to the centreline of the post.
• Tick the box on the form to indicate whether the long wire "sense" aerial is fitted.

5. CESSNA AIRCRAFT ONLY: Measure the position of the grab handles on the engine cowling / windscreen base.

PLEASE NOTE: If these handles are not fitted write "N/A" on the order form. If these handles are fitted:

• Measure round the surface of the aircraft skin from the centreline of the aircraft to the centre of the mounting post at the BASE.
• Measure the opposite side to make sure it is in the same location.
• Complete the box on the form to indicate this information.

6. PIPER RETRECTABLE GEAR AIRCRAFT ONLY:

These aircraft can have a "Gear Release Pitot" on the port side of the aircraft:

• If this is not fitted tick the "NO" box on the order form.
• If this IS fitted tick the "YES" box on the order form.
• If possible email a photo to us for position confirmation. We have these positions on our patterns.

Types of Aerials. <Link to images of aerials>

VHF Aerials: - Usually take one of two forms.

• 1. Base and Whip type - measure to the front of the base and note the length of the base.
• 2. Blade type - measure to front of blade base and note maximum width of blade.

ADF Aerial: There are two type of ADF aerial - the traditional "mounting post" with a long wire to fin, or the solid state combined loop and sense aerial in a box. >

We only need to know the position of the post for the traditional type of aerial. The solid state type is usually mounted underneath and therefore will not be affected by the cover.

Glideslope Aerials: usually take the form of a 'V' or 'Boomerang'.
• Small types - often found on Piper aircraft - can be closed under a hat.
• Large types - often on Beechcraft aircraft require a special type of closeout.
• In both cases measure to the forward-most point of the aerial base and note the length of the base.
• Please include a photo or rough sketch with dimensions.

GPS Aerials:
1. 'Shark Fin' ('Garmin') type. Measure to the front of the base and note the length of the base and the maximum height of the aerial. A snood is fitted for this type of aerial.
2. Solid state 'Flat' type. Measure to the front of the aerial and note the length of the aerial and that it is a 'FLAT type aerial. We fit a reinforcement for this type of aerial.

Anything Else: Please mark it on the form - too much information is better than not enough!
