Two plane spotters were facing up to three years in an Indian jail after they appeared in court accused of illegally monitoring aircraft.
Stephen Hampton and Steven Ayres aroused suspicion after asking hotel staff for a room overlooking a runway at Indira Gandhi International Airport.
They were carrying an air traffic control scanner, laptop, binoculars and cameras.
Their arrest on February 15 came just two days after a bomb blast at a German Bakery in Pune, the first major strike of its kind in India since the deadly Mumbai attacks in November 2008.
The men avoided spying charges, which carry a jail term of up to 10 years, but were charged with a lesser offence under section 20 of the Indian Telegraph Act which carries a three-year jail sentence and or a fine.
The men appeared at Patiala House Court, Delhi, when defence lawyer Rajeev Awasthi indicated they will plead guilty if the court accepts a fine as punishment.
Hampton and Ayres, both railway workers from Bristol, were released on bail but cannot leave the country. They were due back in court for a further hearing on March 3.
Mr Awasthi said: "We have indicated to the court today that in case we are being let off with imposition of a fine we are willing to plead guilty. We need to prove that this is not that serious which requires an imposition of sentence.
"They have done it without realising this is an offence in this country. There is no malice or motive behind it."
Hampton's mother Eileen Cock said she was relieved the men were no longer being held in the New Delhi immigration centre. The 79-year-old retired secretary from Bristol said: "I feel a great weight has been lifted off my shoulders, at least for a few days."
