Hawaiian lift off

[soc-hpjester]

They were about 75 miles off the coast when they turned around and did fuel burn off at low alt. back to phx. then swapped aircraft. About 6 hours late.

A naive question...so how many other critical systems have no back-up in case of failure? none?

There is more than one HF radio on an ETOPS equipped aircraft. But nobody here has confirmed that was the real reason the aircraft turned around.

You need 2 hf's for etops if you are not to midpoint yet.

Quick question... what is an HF radio?

 

[soc-hpjester]

high frequency I think.

Correct...........high frequency.

 

[a320av8r]

HF means High Frequency. The radio waves are capable of "bouncing" off of the atmosphere so they have a longer range than UHF or VHF (Ultra and Very High Frequency), which are strictly "line of sight". HF radios also typically have much more output power than UHF/VHF to get that range.
Actually with todays communications I don't understand why they just don't use SATCOM (Satellite Communications).
HF is like a high power CB radio (CB actually uses HF frequencies) and communications is very dependent on atmospheric conditions (thus the "crackle").

Not equipped with SATCOM. Probably an option on our newly delivered A/C due to SATCOM data in the tech-data. If there are too many more HF radio issues I wouldn't be surprised if the company reconsiders.

It's an FAA/ICAO thing, not Airways.

The 330s have satcom..that is it.

u west 757 have 2 hf but to need 2 to go into the EEP. If one failed after entering EEP it is up to crew to turn around or no

Who is doing ground work in HNL, OGG?

Aloha at all HI destinations.
