What’s the best way to estimate small home projects?

NoraSilas — Wed, 22 Apr 2026 10:20:07 +0000

Estimating small home projects is not very difficult, but it needs a clear and simple approach. First, you should review the scope of work and understand all requirements like materials, labor, and time. Then, checking current market prices and using past project data can help make a quick and realistic budget. It is also important to add a small contingency to avoid unexpected costs. Many contractors take help from professional residential estimators because they make the process faster and more accurate, especially when time is limited and budget control is important.

Apologies, our servers were unavailable for most of 22 April after the Council shut down power to the airport. We experienced some difficulty restoring the server systems once power was returned. Services should now be back online and operating normally.

CPL Performance Figuring out how the online course fits with the book

Melanie — Sat, 04 Apr 2026 03:27:27 +0000

I am working my way through the book and doing the online course at the same time. I can't figure out how the course fits with the book.

So far I have watched videos 1-6 carefully. then looked through 7-12 to see how it fits, but cannot make them work against the book.

Video 1 - Pages 1-5

Video 2 - Pages 6-14??

video 3 - Pages 16 - 19??

Video 4 - Pages 22 - 65?

Video 5 - pages 67 - 109 - but there does not seem to be any video on climb gradient, GS and time interval,

Video 6 - pages 137 -?

Video 7 - jumps back to page 110 - 119??

Video 8 - pages 120 - 136??

Video 9 - pages 139 - 150?? - this video just starts in the middle of a sentence

Video 10 - pages 151 - ?

Videos 11 and 12, I can't figure out how they fit in.

the problem is, after video 4 it appears to be chaotic for videos 5-12.

Can someone help me out with the structure please.

IREX Questions

Christopher — Thu, 02 Apr 2026 13:09:09 +0000

Hi everyone,

I have a few questions and I have the exam soon.

If you only have 1 VHF + 1 HF Com and you need an alternate, and that alternate has PAL, do you need to carry 30 minutes holding fuel if flying by day AND/OR night or do you only need the holding fuel if you're flying at night? AIP ENR 1.1 10.7.4.4 doesn't really specify at what time of day you need it.

Will I have to calculate BOD for a certain destination aerodrome in the exam if I need to calculate holding fuel for BOD + 10 mins or will the BOD be given in the question?

The textbook says that you can use Grid LSALT in the calculation of alternate minima and takeoff minima for aerodromes withn no published IAP, however, the regs for visual approach requirements talk specifically about LSALT/MSA for "the last route segment". I looked up the specific definition of a route segment in the ERC low user guide and it says that a route segment has a defined LSALT, track, and distance etc. Doesn't that technically mean you can't use Grid LSALT because it's not a "route segment" LSALT?

Also, I was doing a practice exam and got this question:

You are approaching Townsville at 0312Z. You wish to obtain the latest meteorological reports for your arrival.

The time and frequency on which the next VOLMET for Townsville will be available are -

Select one:

0330 on HF

0400 on HF

the current time on VHF

0330 on VHF

I selected current time on VHF because I thought you could use the Bellenden Kerr VOLMET (119.75Mhz) or the Mt Blackwood VOLMET (119.85Mhz) but the correct answer was 0330 on HF. Is it based on the fact that you need to be on continuous listening watch on at least 1 VHF frequency and that's why you select the HF VOLMET? I'm a bit confused here as well.

Thank you

Runway Distance Supplement RDS

My ERSA from Nov 2024 does not have the RDS, is the RDS version required for the CPL CFPA exam or is this info provided for in each question? Thanks

ERSA Conversion Tables?

jacobcarnall — Thu, 19 Mar 2026 10:33:44 +0000

Hello! I haven’t updated my ERSA for a while (don’t worry, I haven’t been flying!) - but am getting back into it.

My ERSA from 2019 has conversion tables in it, but I can’t find them anymore in the current ERSA.

Does anyone know where they have gone?

Practice Exam Question

Joshua Guyer — Fri, 13 Mar 2026 09:29:18 +0000

Can anybody help me decipher this question? I read it as, I had COMPLETED 2 early starts and due to Appendix 4 Para 11.3 (Maximum number of consecutive early starts permitted in a week is 3), I could only do one more early start therefore I had selected D. (1). Thanks in Advance.
